Very happy overall and will purchase another for the next transmission.Ī few pics of the work below - sorry not much on the shift kit install itself. Eliminated the issue of traction control cutting the power on the upshift at small throttle openings too. Once the new shiftkit had been fitted, the shifts were instantly smooth at small throttle openings and there was no driveline shock when put into gear. I opted for one shim as I wanted it to shift as smooth as possible. Also, for the 1/2 accumulator you can choose whether you want to use 1,2 or 3 shims to firm the 1-2 shift.

To get a nice 3rd shift, and to allow adequate flow to release the second gear servo it seems that 0.100-0.110' is the best size drill bit assuming mostly stock components.

I've done quite a bit of research and the general consensus is to stick with the smaller sized holes recommended by transgo in the instructions EXCEPT for the 3rd feed. There are a number of holes that need to be enlarged. The spare valvebody meant I could do 95% of the work before disassembling the transmission. I ended up using a brand new (thicker) separator plate and another valve body so that I knew that it was standard before I started working on it.
