Converter slipping going downhill..?
#11
I can’t believe I never posted the solution to this but here it is.
It it has nothing to do with the tq converter, transmission or tune. It’s the transfer case. This was 3 trucks ago for me so my memory is a little fuzzy but I believe it was a worn fork that allows it to be between gears when being driven backwards(wheels driving the rotation of the drivetrain-not the engine(not physicaly driving backwards)). But then it realigns when imput torque comes from the engine again. Get a new transfer case, rebuild yours, either way you will solve the problem. I had a pump rub kit in mine, still did it, 2 different issues.
