Just swapped in a rebuilt t56 in my SRA 99 gt and the shifter will move about and inch towards me when accelerating and and inch away from me when decelerating in gear. There is also some overall slip back and forth in each gear. This is with an mgw short throw. The movement is so bad that it has popped me out of 6th gear when decelerating on occasion. My only thoughts are motor and trans mounts? Or maybe the shifter bushing the ball rides in?
