#Transgo 4l60e shift kit with accumulator piston install#

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. 4L60E Level V 1997-2005 Chevrolet Corvette. This item TRANSGO Transmission kit 4L60E, 4L65E, 4L70E and 4L75E 93-07 Except Hybrid units. Eliminated the issue of traction control cutting the power on the upshift at small throttle openings too. TRANSGOs HD2 shift kit ha a correction for this to crispen up the 1-2. 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. OEM INTERMEDIATE HIGH ENERGY BAND, 1999 AND U P. 7 Clutch 3/4 Stack-Up with Raybestos GPZ High Energy 3/4 Frictions / Full Thickness Kolene Steels. 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. Is there anyone that has experienced this issue.

I used the TG 3 spring pack in the 1-2 accum and piston at the top next to the plate. Now I have a very harsh 1-2 shift at low speeds.

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. Installed a TransGo shift kit and plate along with Sonnax pinless accums, Corvette servo and boost valve.
