If I recall correctly, motor for both years is the same, however there were some subtle differences in the transmissions. They will mount up the same, but I believe the fourth gear on the 4t65E has a longer gear ratio. So to answer your question you should have no issues bolting the transmission to the motor… But since you're removing the motor why not remove the motor and transmission from the donor car??
