Trans Fluid Compatability

#1

I bought a quart of transmission fluid that’s a full synthetic composition. I would like to know if it’s compatible with the non-synthetic fluid already in the transmission. Will I have problems if I mix the two types?

As long as it meets the GM specs for your car, no problem.


#3

Always use the transmission fluid recommended by the vehicle manufacturer.
