Computer tuning with the 4L60E. help.
the issue comes up during manual shifting. If the car is held down in 1st for to long it will hit 2nd gear hard and stay there UNTIL the car is shut off and sits a while...almost like a safe mode thing.
Both these cars have been dyno tuned and tuning for the stall has been done, but I'm wondering if there is something we are missing..
Are these stalls bigger then normal and the computer thinks its slipping? No codes are pressent when this happens but something seems like its making the computer stick in safe mode or something... any tips greatly appriciated
