I have:
Rebuild 4L60E
Alto High Performance Clutch Pack
Full Transgo HD2 shift kit installed (installed springs for comfy ride)
And Corvette Servo
Car shifts fine but there is approx 15% Throttle - 50% i think a bang noise.
Not loud, also a little bit in 1st.
I think it has to do something with torque management in the trans, can someone help?
Raising or Lowering? What values?
I like the trans to be a high life expectancy, just my regular daily driver with kids.
Thx for sorting this out.
This is my tune.
(only adapted shift points) all the other stuff was left untouched. I like to eliminate the bang in 1st and 2nd with low to medium throttle. (haven't tested out high throttle since everything is new)
