These are pictures from the Transgo Shift reprogramming kit install i did. This kit will give you nice quick shifts that get progressively stronger as the RPMs go higher. It was a great improvement and it says it will prolong the life of your transmission. It can be purchased from Dana at www.pro-built.net it is a customized kit he has put together from two of the Transgo kits, including new .500 boost valve and corvette servo.
