This transmission was pulled from a 94 Mitsubishi 3000GT with 123k miles. The transmission shifted smooth on our test drive. We did not test it at high rpm shifting. Normal driving, this transmission shifts smoothly through the gears. This is a direct swap for 94+ models. If you have a 93 model, you will need to change out the speedo drive gear assembly. For 91-92 models, you will need to do the speedo drive gear swap and CV/Intermediate shaft axle swap from a 93+ model.
