HELP!! 4L80E Issues
I just built and installed a 4L80E in my 68 Camaro. Yesterday was the 1st time to try it out. It has a major problem. When it upshifts it locks the rear wheels. Using the Baumann controller, I've got it set to upshift to 2nd gear at 20mph. As soon as it hits 20mph, it'll lockup then down shifts back to 1st and starts turning again. I was able to pull the shifter down to 2nd and it started off in 2nd, but when it upshifted to 3rd it did the same thing. I pulled the rear servo and shorten the pin to the shortest length, but that did'nt phase. Does anyone have recommendation on where to start looking?
Thanks,
Jim
