The problem with the Jeep is that it shifts into 4th gear sooner than the cars and that slow 3-4 shift with increased hp and weight just kills the tranny.
ya, my 3/4 shift takes like a week The tranny is on its last legs no doubt, I have the nitrous turning off at 5800 rpm and it still slides like a mofo during the 2/3 and 3/4 shifts.
