Does it matter what transmission fluid I 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.

Is all transmission fluid the same?

Always check your owner’s manual for the type of fluid recommended for your vehicle by the manufacturer. Most, but not all, transmission fluids are blended with synthetic base oils to offer better performance, with improved resistance to heat, cold, oxidation, friction, and shearing.

What happens if I put the wrong transmission fluid in my car?

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.

Is Synthetic transmission fluid better?

A synthetic fluid has the capability of providing your transmission with a smoother operation. Because of superior engineering, the synthetic fluid is better at lubricating your transmission and is able to sustain its viscosity in a broad temperature range. … This will likely be true even with variations in temperatures.
