This kit is for a th400 GM Transmission. It has two different kits in this kit. One for mild shift and the other for a stiffer/harder shift. I am using the mild shift kit and it works out great for street driving.

I like the shift kit, but have not used it yet to see if it is all there and works.

I installed this on my Th400 in my 1984 C10. It made my shifts considerably more noticeable and removed all slippage. I am 100% satisfied and would purchase it again. Also the instructions were super detailed and walked me straight through the process. Can't wait to take it to the track!
