Can I use any automatic transmission fluid?

Each car has its own recommendations from the manufacturer on which transmission fluid your car needs. Some transmission fluids are very incompatible with different transmission types as they use different additives in the fluids.

Is all automatic transmission fluid the same?

Automatic transmission fluids have specific viscosities, friction coefficients, and additives. ATFs are engineered to work with the design of specific automatic transmissions. They are not all the same.

Does it matter what automatic transmission fluid you use?

Even if you change your transmission fluid, you never will be able to drain all of the fluid from your system so it is important to use the same kind of fluid. It is also important to use the correct type of automatic transmission fluid because different fluids have very different properties.

What happens if you use the wrong automatic transmission fluid?

Automatic transmissions must only use the fluid specified by the automaker, such as General Motors’ Dexron series or Toyota’s Type T. 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.

What is the difference between ATF and ATF 4?

ATF +4 is a synthetic fluid for finely-tuned transmissions, so if you use a non-synthetic ATF instead of ATF +4 in a car or truck that calls for it, you could damage the transmission. You may use ATF +4 in most applications that call for older Dexron and Mercon fluids.

Is Synthetic Automatic Transmission Fluid better?

Synthetic transmission fluid is made to last longer than conventional types, so you can go longer between fluid changes without sacrificing quality lubrication. However, synthetic oil costs more, so we recommend you do the math to see which type of transmission fluid will cost you less over the life of your vehicle.
