Ive been reading and understand the issues with the 4t65e tranny. Though I never had any issues with my 02', Id like to use this kit in my 07' GXP as a precaution. Does anyone have the instructions for this kit they can post up? I didn't see that it did anything for a 3-4 shift, is this true?

Also, I saw somewhere that to install this kit (properly maybe?) that you need to get to the side of the tranny where the valve body is. Is this true? All the threads I've read are about people dropping the pan and doing the 1-2 and 2-3 stuff. Where is the 3-4 accum., on the side by the valve body?

Any info. would be appreciated. Just wondering if its just a simple pan drop, or If I have to get to the side of the tranny too? I havent seen anyone post pics of side work, or heard much talk about it either.

Thanks for any input!

I'm in the middle of a rebuild for my transmission and I installed the Transgo SK4T65E kit. In the kit, the 3rd clutch inner lip seal is replaced with a chamfered seal that has a coil spring underneath it. On the 1-2 accumulator underneath the piston, a white spring is added along with a .75" spacer. On the 2-3 accumulator underneath the piston, a red spring and a white spring are added along with a .75" spacer. On the top side of this piston, a .530" spacer is added. In the 3-4 accumulator, both springs are replaced with a yellow and red spring. Finally, in the valve body, the reverse boost valve, the line boost valve and the pressure regulator outer spring is replaced. The 3-4 accumulator is located on the back side of the channel plate which covers the sprockets and chain. Hope this helps you out.
