Art Carr 4l60 problems
But I noticed if your in OD rolling along and stab it. It don't really like that! It hesitates and hit the rev limiter then shifts down. So I just started manually down shifting. But still if you don't time it right it will hit the rev limiter when your upshifting.
Today I noticed ,manually going through the gears, it slips going into the next gear. Why? this sucks.

Is it tune related or just the trans slowly letting go?
Any info would help
Its got a 3.42 12 bolt. I was driving it over to get a 3.90 install in it when it started slipping
