Brand doesn’t matter but fluid specifications really do, especially with automatic trans fluids. Put the wrong stuff in and your clutch packs burn out fast. Same applied to limited slip differentials. It has to do with the ‘friction modifiers’, additives designed to make the clutches slip (or not) properly.
Does it matter what brand of transmission fluid you use?
You have different brands with different mixtures and additives designed for specific types of transmissions. Using the wrong kind of transmission fluid in your car can lead to major damage over time.
Is it OK to mix transmission fluid brands?
You should not mix the old transmission fluid with a new one. The main reason is it won’t offer you the ideal viscosity. At the same time, the mixing will reduce the performance of the transmission system. So it will cause overall engine performance.
What brand transmission fluid is best?
Our top pick for the best transmission fluid is the Castrol Transmax Dex/Merc ATF. It works for the majority of domestic cars out there and delivers great results. If you’re looking for something even more wallet-friendly, check out the ACDelco Dexron VI Synthetic ATF.
Are all brands of transmission fluid the same?
ATFs are engineered to work with the design of specific automatic transmissions. They are not all the same. Moreover, if your vehicle is still under warranty, using a fluid thatis not approved by the vehicle manufacturer will void the transmission warranty.
What happens if I use the wrong transmission fluid?
Using the wrong fluid can cause poor lubrication, overheating, and possibly transmission failure. A mechanic might not be able to reverse the damage, even by flushing the transmission. Mistakenly adding motor oil or brake fluid can also destroy your transmission.
Do I need to use OEM transmission fluid?
The answer to the question, “Do I really need OE specific fluids?” obviously is no, but you need to make sure the fluids you chose are designed to perform the way the OEM fluids do.
Can I add synthetic transmission fluid to regular?
Transmission fluids of the correct type for the specific transmission can be mixed with synthetic, and non synthetic, unless forbidden by the vehicles manufacture.
Can you add synthetic transmission fluid to regular transmission fluid?
Yes, you can mix a conventional and synthetic transmission fluid of the same specification.
Can you mix CVT transmission fluid brands?
No, absolutely not – unless your “automatic” is a CVT, and then you must use CVT fluid. ATF and CVT oils are chemically completely different fluids with different additives, base stocks, viscosities, friction coefficients, etc.
How do I choose transmission fluid?
The easiest way to make sure you’re using the right type of ATF is to check the owner’s manual. It’ll tell you exactly which ATF the manufacturer recommended for your car. You may also find a recommendation on the dipstick. Either is a reasonable resource for determining the right type of fluid for your transmission.
Is O’Reilly transmission fluid good?
O’Reilly transmission fluid provides protection against wear and transmission shudder and resists thickening due to high temperatures. Transmission fluid from O’Reilly also offers friction stability to maintain smooth and consistent shifting performance.
Is dexron VI transmission fluid synthetic?
Valvoline™ DEXRON*-VI/MERCON* LV ATF is a full-synthetic transmission fluid formulated with advanced additive technology to meet and exceed the requirements of the General Motors* DEXRON*-VI specification.
Are all CVT transmission fluids the same?
The fluid requirements for CVT transmissions are very different versus a typical stepped gear transmission. Each specific CVT fluid is formulated for a specific transmission; however, oil marketers have been able to demonstrate good performance with a single CVT oil across many different transmission designs.
Is tranny fluid universal?
Ultra1Plus™ Transmission Fluid Full Synthetic ATF Universal is a universal automatic transmission lubricant which is suitable for use in nearly all makes and models of automatic transmissions including passenger cars, light trucks, heavy-duty trucks, commercial vehicles, as well as off-road vehicles.
Are there different transmission fluids?
In general, there are two main types of transmission fluid: automatic transmission fluid and manual transmission fluid. There is also synthetic transmission fluid and specialty fluids used and specified in various types of transmissions including CVT and dual clutch models.
