Some recommended products may use affiliate links. It is a synthetic blend with tighter internal tolerances and higher shear strength than fluids like Mobil 1 ATF Dexron 3. ATF also works as a hydraulic fluid for power steering systems and some 4WD cases in automatic cars. The fluids are designed to have low viscosity and viscous friction. The fluids are not identical and the differences in additives/formulations can cause issue with seals and other components. It is always better to follow your manufacturer’s instructions about using the various fluids in your car. So using the wrong fluid in both manual and automatic transmissions can quickly wear out the bearings and gears while producing strange noises and failure. The differential works with the transmission to deliver power from the engine to the axle to rotate the wheels. If ATF is okay for your PS the owners manual or reservoir should state that you can use Dexron, Mercon, etc. What is the difference between DEXRON® III/MERCON® and type F transmission fluid? Watch as an ACDelco product specialist explains why it is important to follow OE specifications when it comes to your power steering fluid. It is better to always perform a transmission fluid flush that gets rid of all the debris in the transmission before pouring fresh, new fluid into the car. [easyazon_image align=”center” height=”500″ identifier=”B008MISB2Q” locale=”US” nw=”y” src=”https://myengineneeds.com/wp-content/uploads/2019/03/41sXPhxKPKL.jpg” tag=”myengineneeds-20″ width=”255″], [easyazon_cta align=”center” identifier=”B008MISB2Q” key=”wide-orange” locale=”US” nw=”y” tag=”myengineneeds-20″], Your email address will not be published. This indicates it’s time that the fluid is changed. Under normal circumstances, approximately 4-4.5 quarts of MerconV will be present in the actual “fluid pan” of the transmission, with the remaining 9.5 quarts in the torque converter and in the cooler lines. The most common services offered will be "fluid changes" and "fluid flushes." It’s the petroleum companies who do that. Actually, a lot of manufacturers use ATF instead of power steering fluid. Â. The only instance it may be okay to use transmission fluids in a steering pump is during an emergency. Different types of transmission fluid are necessary for automatic and manual transmissions. They now have their specific automatic transmission fluids (ATF) and steering room fluids, for different brands of cars. The loss of braking power could result in a serious accident. Instead of using the car manufacturer’s previous set formula, they try to make a new fluid that meets various manufacturers’ original specifications. This is when you wonder if can you mix Dexron 3 with Dexron 6 because the Dexron 6 container reads that it is okay to use in vehicles recommending Dex III. Dextron ATF As a substitute, Penzoil company has a marine tilt-and-trim hydraulic fluid that can be used for power steering and tilt-and-trim systems. A: The basic colors of power steering fluid are red, pink, and clear. Filled to the top, the pump ran much quieter and was more responsive. Valvoline has a range of transmission fluids that meet most vehicles’ manufacturer specifications. Without a good knowledge of the power steering fluid color, it will be slightly challenging to diagnose vehicular problems. They thus end up producing ‘multi-vehicle’ ATFs like fluids that meet the specifications of both Dexron III and Mercon V. Customers thus find it difficult to find out if a particular multi-vehicle ATF is suitable for a specific vehicle because these multi-vehicle ATFs are manufactured to suit the standards set by the petroleum company. This Valvoline Mercon lv fluid is suitable for all modern automatic transmission applications except for ATF+4 and CVTs. Is it okay to mix power steering fluid with transmission fluid? They usually have the words ‘Use automatic transmission fluid’ or ‘Use Dexron’ or ‘Use Mercon’ inscribed on the fill cap or in the owner’s manual. However, both contain the same seal materials that resist hydraulic fluid breakdown. Fluid heated by the transmission, engine, or power steering pump flows to the cooler. These formulas comprise of base oils and additives and the license fee lets the oil company use the automaker’s proprietary ATF brand name.

Can you use Transmission Fluid in a Power Steering Pump? Lucas 10001 Heavy Duty Oil Stabilizer 32 oz, Archoil AR9100 Oil Additive for All Vehicle. It is generally not advised to mix transmission fluids in older transmissions but may be ok in small amounts when inevitable. It is compatible with Dexron VI, Mercon V, and Mercon lv and works on most European cars including BMW, Audi, Saab, and Mercedes-Benz. However, GM does not advise using fluids like Amsoil Dexron VI in non-GM make vehicles that used Dexron III ATF power steering fluid. So while VW and Audi have their own transmission fluids in varying numbers, most of them are ZF HP 19 Trans and are Dexron Mercon 3 with added friction modifiers. Besides, the recommended power steering fluids are not so expensive and are as easily available as tranny fluids. There is however some models that may work when mixed, especially if the fluids are about the same viscosity. For some older vehicles you can use transmission fluid in the PS reservoir; however, this is not common in modern vehicles. It … This applies to manual and automatic transmissions. This means you will be fine if you add Dexron Mercon in a ZF transmission at first, and then add the right fluid. Besides, if your vehicle is under warranty, using a fluid that isn’t approved by its manufacturer leads to voiding the transmission warranty. This is especially true in Honda/Acura and Toyota trannies because their ATFs are designed to work in the transmissions they were designed for. An ATF is basically a closed system and the lubricant must last for a long period of time. The ATFs quality and applications are generally based on their own testing and not by tests conducted by the vehicle manufacturer. Dirty power steering fluids without the right additives only make things worse. The reason for their incompatibility is because different companies use different adhesives in their fluids to bind frictional material to the clutch disks in the transmission’s drums. Differences between Power Steering Fluid and Automatic Transmission Fluid, About Valvoline Automatic Transmission Fluids, About Castrol Automatic Transmission Fluids. They can also withstand reasonably high temperatures and easily flows through thin tubes. In other words, the wrong fluid can with time wear out the synchronizer rings to lead to premature failure and an expensive transmission rebuild. Lucas makes a power steering fluid which is just for power steering. Well, it is basically okay to mix Dex 6 with Dex3 as long as you filter and replace the drained fluid, and there are no shifting problems. Come join the discussion about restoration, builds, performance, modifications, classifieds, troubleshooting, maintenance, and more! Most of the time oil companies try to streamline. Always be careful, and avoid using multi-vehicle ATFs advertised to be suitably used in various vehicles. Mercon lv is the latest ATF from Ford that’s factory filled in 2008 and later Ford cars. It's proven to use Honda genuine parts or fluid for Power Steering, Transmission Oil, Engine oil, Brake oil may extend the life span of wear and tear parts. However, I would find the recommended specs before I made the substitution, even on an older vehicle. The Valvoline Type F transmission fluid is a high quality NON-friction modified fluid. You should however never use automatic transmission fluids in a Honda power steering system. Most of Castrol Transmax products like the Castrol Transmax Devron VI include Smooth Drive Technology comprising of active control molecules that automatically adjust their friction level even in varied pressures and speeds. What are Transmission Fluid and Power Steering Fluids? In automatic transmissions, the fluid also acts as a coolant and helps transmit power. This includes the products licensed by Ford, GM and Chrysler and fluids meeting the JASO requirements of popular Japanese imports from Nissan, Honda and Toyota. There may be situations where you may have to refill your tranny fluid, only to find out that there is still some Dexron 3 remaining in the transmission. Common names here are Dexron, Mercon, and ATF+4 which are the brand names of General Motors, Ford and Chrysler fluids respectively. It has very little smell but a keen nose will detect a dull, mechanical scent.  ATFs offer the advantage of having detergents in them which help keep your system clean. These companies produce transmission fluids based on the formulas licensed by the company. In some cases, the transmission may entirely fail too. The vehicles that used to run on the old ATF formulas usually also run in the new ATF. This makes it ideal for trannies designed for it but not so good for trannies that aren’t. Transmission fluid is a lubricant used in the transmission of a vehicle. As it is not compatible with the earlier Mercon fluids, it cannot be mixed with Mercon or Valvoline Mercon V if replacing them. Make sure you check its level at least once a month using a dipstick so that you change it on time and avoid any transmission related problems. But I chose to use PS fluid along with Lucas PS fluid with conditioners. They have been superseded by Dexron III which in turn is superseded by Dexron VI. So instead of going through all these problems, it’s better to just use the right fluid. For a better experience, please enable JavaScript in your browser before proceeding. automatic transmission fluids for their power steering. Automatic transmission fluids are necessary for various reasons like lubricating, cooling and preventing rust in the transmission. In fact, it’s not compatible with other fluids too. This has lead to many car makers adopting Dexron and Mercon formulations as their specified automatic transmission fluid like Motocraft Mercon ATF power steering fluid. Identify the consistency and smell of the leaking fluid. JavaScript is disabled. The most commonly used power steering fluid substitute is automatic transmission fluid (ATF). Transmission fluid acts as a lube and coolant for your Transmission. This is a power steering fluid leak spot and a sample of the fluid. Differential fluid. Even putting the wrong fluid in a CVT transmission may lead to it working well for a while because of the remainder CVT fluid in it. No stop leak though. There is usually progressive damage done to the tranny where while it seems fine at first, it later starts to either slip or shift poorly. You wonder if mixing the fluids will create problems or if it is better to have it flushed by a dealer with a filter change. The power steering fluid is just as important as the engine oil. What happens if the wrong Transmission Fluid is used? It’s due to their additives which may end up blocking the power steering system’s actuator and a fluid pump. You may notice these color fluid when leaking if your power steering fluid is changed recently. The manufacturer will list a spec for the fluid requirement, and whatever fluid you use should state on the bottle that it meets that spec. Some power steering fluids need Dexron like Dexron power steering fluid, or other similar types of ATFs, while other car manufacturers are specific about using fluids that are specialized for the steering wheel but has slightly different properties. Here is more about Dexron and Mercon transmission fluids that were in the market but have been superseded now. My 1956 can use either PS fluid or ATF. The power steering fluid refers to an oil/petroleum-based fluid commonly used as a lubricant and pressure transfer medium between different metal-on-metal contacts. It’s the detergents in the ATF that helps keep all the contaminants away from the transmission. The vehicles have grown technologically so much over the years that they have also become delicate and sensitive in their own means. Mainly functioning by adding enough pressure to the pump, power steering fluids are crucial in optimizing the performance of a vehicle’s power steering system, which gives drivers more control over the steering wheel. While old Valvoline type FA is generally harder shifting fluid, Dexron III is a lighter option. The best way to choose the right ATF for your car is through the owner’s manual which states the recommended ATF when the car was new. Castrol automatic transmission fluids are formulated to restore smooth shifting in vehicles. Both oils are used for their hydraulic properties, But in trans fluid, there are friction modifiers that help the clutch packs engage. The only difference between power steering fluid, and transmission fluid, is the detergents in the transmission fluid are not there in the power steering … So while Valvoline Max Life synthetic Trans fluid can be used instead of type F Dexron or Mercon in some transmissions. Power steering helps you turn the wheel so it's not like trying to turns a tank, if you have ever lost your power steering you know what im talking about. It also accumulates the dirt and other metal shavings flowing through the car’s system or sitting at the bottom of the pan. This, in turn, leads to the shifter feeling stiff or the shifter not falling into gear. Power steering fluid and Auto trans Fluid a 2 different things. And unlike in manual transmissions, automatic transmission fluids tend to break down under normal use because of the high operating temperatures. This means that they can easily withstand as much as 1000 PSI of pressure without heating up much while at work. Though these fluids are quite different from one another, they do have their similarities. LISTEN TO THE FIRST GUY WHO ANSWERED. There are a few differences between automatic transmission fluid and hydraulic oil. Most of the vehicle manufacturers design their steering systems to run under specialized PS fluids to give best results. This has also led to many oil companies claiming that their Dexron/Mercon ATF can be used in various vehicles besides General Motors and Ford. It is safe and okay to use automatic transmission fluid on the systems that are designed to run on them. Amazon and the Amazon logo are trademarks of Amazon.com, Inc or its affiliates. As you won’t be changing transmission fluids as often as you change motor oils, it is always better to use the best fluids which effectively increase lubrication and reduce heat. I put that in my new hot rod pump. And the last years have to lead to major automakers introducing many fully synthetic ATFs that are better than their conventional ATFs. 2. Like engine oil, heat causes wear on differential fluid, which can lead to excessive wear on the gears and bearings. However if you add these fluids to cars that are supposed to run only on ATFs like Mobil 1Dexron VI or Mercon lv then you end up voiding the transmission’s warranty. An example is the Valvoline MaxLife ATF which is synthetic in nature and uses Group III paraffinic oil as its base. The difference between Dexron II and IIE was its oxidation inhibitors. Not using any ATF, or using the wrong one for your vehicle, can lead to the transmission overheating and producing debris. Your car’s transmission is responsible for converting the engine’s power into motion for the wheels. Manual transmissions do not require any specific fluids like synthetic oils and ATF. Transmission fluid plays an important role in this conversion. The fact that it is a synthetic fluid means that it comes with an extended drain interval. If you are lucky, just changing and using the right ATF is all that’s needed to rectify things. However, you should note that the earlier fluids are not forward compatible with a transmission designed for Dexron 6. However it should not be used on systems that specifically require power steering fluid. Adding any brand or general ATF into their transmission can lead to immediate failure of the tranny because of lubricity change and hydraulic properties. You'll be able to differentiate between those fluids and transmission fluid by the consistency and smell. Dexron VI synthetic transmission fluid can lead to the failure of line pressure in older transmissions. ATF Basics: • ATF is a complex fluid full of lubricants and detergents that keep the transmission running smoothly with minimal wear. Dexron, Dexron II, IID, and Dexron IIE are the original GM Dexron ATFs but are not licensed by the company anymore. They also transmit the required hydraulic force while steering. Old transmission clutches generally engage at fixed line pressure. Brake fluid is sometimes difficult to distinguish from power steering fluid as it has a similar texture and color. Your email address will not be published. It is not advised to do so because it may lead to the compromising of your transmission seals because transmission fluids have a different formula. There may not be that many particular transmission fluids for a manual transmission but in case of automatic transmission, it all depends on what you use, the Trans you have and what fluid it requires. This is because it has a much lower viscosity out of the bottle when compared to other ATF or Dexron ATFs. However, if you aren’t lucky, then the tranny may get so damaged that it needs a complete rebuilding or replacement. However, in case of too high pressures, the pistons may slam too hard and cause damage. It can even smoothen the shifting of gears in cars that have run more than 75,000 miles. Brake fluid leaks can be found anywhere underneath your vehicle. This is integral in today’s driving condition which can lead to an uncomfortable ride and damage if the transmission fluid doesn’t protect the transmission moving parts. So you do not end up saving money by using an ATF in your power steering system. Dexron VI is the latest GM ATF developed in 2006 for the latest six-speed automatic cars. Power steering fluid is a low viscosity hydraulic fluid used in a vehicle’s power steering system. Automatic transmission fluid is a medium which transmits power from a car’s engine to its transmission system. It also contains additional friction modifiers that make it more slippery than Mercon. Dexron IV transmission fluid is an upgraded version of Dexron III that was briefly used by GM. Power steering fluid is a slightly yellowish liquid of medium thickness, kind of like cheap waffle syrup mixed with water. With so many features in them, it’s no wonder that there are so many types of steering fluids in the market in varied formulas. Though expensive, Dexron VI synthetic can be used in any proportion with past model vehicles that have an automatic transmission, instead of Dexron 3. In the simplest of explanations, the primary difference between a fluid change and a fluid flush is the complexity of the process. The biggest problem that may occur in the case of older fluids is line pressure because changed fluids affect viscosity which in turn affects how quickly pressure is used. They may sound similar, but the processes are actually quite different, so we're here to explain what you need to know about each. Although it can certainly be said that transmission oil is one specific type of hydraulic oil. It consists of: 85-90% base oil; 10-15% additives; The process of selecting a compatible automatic transmission fluid can be tricky. The friction modifiers in the automatic transmission help control the heat that builds up while the valves and pump operate in the hydraulic systems. The most common problems that may occur if you mix transmission fluids is slippage or excessive clutch lockup. Power steering fluid colors are pink, red, and clear. This leads to the gradual but eventual wearing down of the transmission parts. You can also tell it is time to change by looking at the transmission fluid colour. Sometimes if you can’t find a specific fluid, the auto parts store usually has a compatible power steering fluid substitute. However, there are some fluids that are entirely different and incompatible with other fluids, which you will want to remove immediately. Using ATF in these systems can lead to the abrupt failure of the power steering system. For those who are still confused with the so many types of oils, fluids and associated terms here is some useful information. Besides, as Dexron and Mercon are similar they are considered to be interchangeable. While automobile companies develop specified transmission fluids for their vehicles, they don’t make them. Power steering fluid is considered as a low viscosity hydraulic fluid which is used in the power steering system of a vehicle. You worry because Dexron VI is synthetic in nature and can ruin the transmission because of the reaction of the different additives in the two fluids. They are usually just Mercon or Dexron III versions. Besides Castrol ATFs are formulated with extra friction durability and anti-wear chemistry that protects all the transmission parts much better and in the process, protects and prevents extensive transmission damage and repair costs. True that you don’t need to change this fluid as frequently as the engine. You however need to know which PS fluid is right for your car so that you can replace it if there is a leakage. The fluid has a low tolerance level and tends to quickly break down, in less than 40,000 miles. They do all this while still supplying the necessary lubricity to protect the rotating pump and sliding mechanical parts from wear and tear. This fluid could only be used in dynamic steering where there’s a pump on one side and on the other side, a cylinder. It is not only compatible with transmission seals; it has an agent as an additive that conditions seals to prevent leaks. There are lots of problems that may happen like the transmission slipping, not properly engaging gear, rough shifting or not working at all. Differences between Power Steering Fluid and Automatic Transmission Fluid The main difference between the two is that ATF contains friction modifiers and detergents. Are there any special specifications for the power steering fluid like there are for engine oils or transmission fluids? Some who use them as hydraulic pumps ( good and cheap ) will put hydraulic fluid in them. Automatic transmission fluid has a high amount of detergent in it, so be sure to check your owner's manual. Motor vehicles no longer run on just petrol and engine oil. smells the same looks the same feels the same works the same in my opinion cant tell a difference. There are however some exceptions in fluids that can be used instead of non-recommended fluids, which are the common fluids, like Dexron and Mercon. Mercon V is the most common Ford ATF but shouldn’t be used in transmissions requiring Ford Type F. It differs from the original Mercon by containing an additive that is not compatible with some older seals. Power steering fluid is similar to some other fluids responsible for an automobile’s unhindered performance (e.g., motor oil and transmission fluid). Exceptional case of using ATFs in Honda Power Steering System. However this is only for a while and it may suddenly stop working, to never work again. In the case of manual transmissions, the wrong fluid can lead to the synchronizer rings in them that match internal gear speeds while moving into gear to work less effectively. A couple of differences are the following: Motor oil is designed to deal with the products of combustion, whereas automatic transmission fluid (ATF) does not see contaminants from fuel burning. Is there a real difference between trans fluid and power steering fluid? A PS fluid is mainly used for its hydraulic ability and ability to withstand and cool what the PS pump can dish out. Dexron III/Saturn was a version developed solely for some Saturn models. Most of the time, car companies stop licensing old ATF formulas once a new ATF formula enters the market. It’s not easy selecting the proper automatic transmission fluid for your vehicle because the wrong one can cause problems. Anybody have any insight to the differences between power steering fluid vs automatic transmission fluid? A power steering fluid is usually marketed as a single fluid, but some steering systems may use different fluids. This leak should also be professionally addressed as soon as possible. This is because Dexron 6 is backward compatible with earlier transmission hardware. So unless your car was originally delivered with Dexron III or an earlier version of it or Mercon or Mercon V fluid like Castrol Mercon V, it is better to check the multi-vehicle ATF’s product data sheet before using it. You could use tractor hydraulic fluid on Saginaw pumps and doubt it would make much difference. Â. The good news is your jeep holds 7-12 quarts depending on the state of fill so the power steering fluid is pretty well thinned out and wont cause any serious damage. While it’s okay to use an ATF in an older Ford or domestic vehicle, it’s a huge no-no in Hondas and Acuras, especially in J-series engines. This, in turn, provides for a smoother driving experience for a longer period of time. The oil company anyway states that the old ATF can be replaced by its new counterpart. Can they be used safely one for the other? This was done because Ford started recommending using Mercon V for all transmissions that previously used Mercon. The transmission fluid is for cleaning and friction. What is the difference between Mercon and Mercon V? While it’s the specified ATF for some non-GM models with GM transmissions like BMW, it’s not specified for use in GM-brand vehicles with non-GM transmissions or cars imported in the United States. It soaks into concrete quickly. But if your power steering fluid is old enough then the color may turn into brown or light black. Never use other fluid than Genuine Honda power steering fluid. Difference was amazing. Instead of going through all these problems and headache, it is always better to use the right and best fluid for your tranny because when you compare the costs of a fluid and the tranny, any fluid is naturally a cheaper and better option. Mercon SP is a Mercon V variant with additional additives while the Mercon CVT is meant for models with continuously variable transmissions. Never take the risk of using a multi-vehicle fluid in your car if you doubt that Dexron III or Mercon ATF is suitable for your car. Both fluids, however, have similar seal materials that resist the breakdown of hydraulic fluids. The fluid is good if it’s bright red in colour with a sweet smell while a dirty and dark fluid emitting a burnt smell means it’s time for a replacement. DEXRON® III/MERCON includes friction modifiers in the fluid additive package. They make these claims just because one model of that company used Dexron/Mercon. Gear oil isn’t the same thing as ATF, and knowing the differences can make or break your car. I have never heard anyone say you can use PS fluid in the trans, though... For PS fluid the answer depends on the make and year of the vehicle. For example, the GM spec for Dexron is not the same as the Ford spec for Mercon fluid or Type F fluid, so you should not try to substitute one for the other. Sometimes the shifter may even grind while trying to put it in. The air moving over the fins of the cooler cools the fluid, which is then routed back to the transmission, engine or power steering pump in a continuous loop through the return line. Gone are those days when you could just use any oil in your engine and transmission. The only models that permit using transmission fluids in the steering pump are Chrysler, Ford, and GM vehicles. There are also some systems that even use automatic transmission fluids for their power steering. Valvoline MaxLife ATF also includes cleaning agents that can clean off deposits from friction-prone parts and even discourages the formation of deposits. Contamination with water makes the power steering fluid foamy. It is backward compatible which means that it can be used in any vehicle that first used earlier Dexron versions, and can be mixed with them. The fluid allows the parts of the transmission to move freely. It mainly functions by adding sufficient pressure to the pump. Castrol boasts of a wide range of ATFs that are engineered to protect important transmission parts. When I bought my Lee 12 to 1 box, he said to use GM Power steering fluid... A forum community dedicated to hot rod owners and enthusiasts. I think power steering fluid is just dexron III dyed another color (sometimes) in a different bottle with an inflated price . Matt Wright/ThoughtCo. We hope you love the products we recommend and just so you know that as an Amazon Associate MyEngineNeeds may earn from qualifying purchases. The other most commonly used power steering fluid is an … [easyazon_image align=”center” height=”500″ identifier=”B007VWRUQC” locale=”US” nw=”y” src=”https://myengineneeds.com/wp-content/uploads/2019/03/515apFHnymL.jpg” tag=”myengineneeds-20″ width=”500″], [easyazon_cta align=”center” identifier=”B007VWRUQC” key=”wide-orange” locale=”US” nw=”y” tag=”myengineneeds-20″]. As assumed, power steering fluid is necessary for cleaning, lubricating and conditioning the power steering system seals.
