I installed the shift correction kit, corvette servo, .471 boost valve, and billet 4th apply piston and cover. The kit was easy to install, and performed as advertised. my only problem was that the part throttle 1-2 shift was too firm for me, so I dropped the pan and put a stock purple 1-2 accumulator spring in, and that softened it a little. I am very happy with it. all of the shifts are noticably firmer, but not harsh. The shift points were slightly extended. Good upgrade to a good trans.
