I'm a new member and I got a 95 dodge 2500 cummins diesel. I just recently rebuilt my 47rh auto transmission and 2nd gear is slipping bad but reverse, 1st, 3rd, 4th OD and lock up are all great. I readjusted the front band to spec. and it shifted okay but when the trans oil warmed up it started slipping again when I got after the throttle or going up hill, but it does ok on flat roads but its nothing like 1st or 3rd gear clamping force. I was wondering if it could be a pressure leak on the kick down servo or a valve body problem. I have the stock strut, anchor, and accumulator.
If anybody has an idea whats going wrong I would greatly appreciate your responses

Thanks
