Mitsubishi Repair: 1989 mitsubishi galant automatic, mitsubishi galant, transmission mounts

Question
We replaced the front and transmission mounts on the car,..it more or less jumps out of gear in drive only when u give it to much gas ..if you lightly touch the gas it does not shift out of gear...but it reverse its fine. could the rear mount cause this to happen or is it in the transmission?

Answer
Tracy,
It's not typical that a bad transmission mount would cause this problem, but it's possible.  Your transmission is controlled by a computer. If you scan it (usually only able to be done by a dealership mechanic), you may find some fault codes that will pinpoint your problem. You may have a sticky valve or solenoid in the valve body.
Good luck!
