Well I would like to thank Baxy for posting this thread and all of the details. I have installed my shift kit. It took be 2 day to do it, but I was being very careful. Along with the Superior Shift Kit, I installed the billet aluminum accumulator piston and an aluminum servo and cover. all the shifts except 2-3 feel firmer. Would the 2-3 shift feel softer because I used the stronger supplying spring on top of the new taller accumulator piston?
