i installed a b&m shift kit. and it didn't shift from 2-3 and the 1-2 shift was super high. so the problem is that in the directions for b&m they leave out the 2-3 piston pin wear the spring used to hold the piston in place. with the little spacers they give you won't hold the piston and on top of the fluid will just flow right through them ( which is not suppose to happen) so you can order the little piston pin witch is about 1/4" diameter and 3-4" long. iam sure you know what iam talking about because you have one for the other piston in the valve body but not one for the one in the tranny. If you have any questions about this email me
