I have a 2005 Avalanche with the 4L60E, and have added Corvette servos.
I have the infamous driveline clunk under very light throttle during the 2-3 upshift. It was there before & after the servos. At higher throttle, it shifts perfectly in all gears.
I have tried adjusting the following without much luck
* lowering pressures at low torque
* raising and lowering shift speeds
* torque management on and off
* lowering 2-3 shift pressure multiplier at low torque
* shift timing as quick as 0.2 sec up to stock at low torque
Any thoughts on how to tune this out?
Thanks
