I had the trans(2 sp F,2 sp R) on this truck rebuilt by a trans rebuilder. After installing it, I had to crack a line to get the fluid flowing flowing.Once this is done, the truck works fine. After shutting it off and it sitting 10 or so mins, it seems ti lose prime. I have to rev it for 3-4 secs or so in gear, and then it will go. Leaving it sit overnight-and I have to crack a line again. Pulled trans and sent it back- rebuilder says it checked fine and they tested it 3 or 4 times with no problem. Put it back in and i have the same problem. Anyone ever run into this? Am I doing something wrong? Thanks in advance

Thanks for the reply. I had the rebuilder finally install a new pump, after I found out that rebulders will not put a new one in due to the high cost. Solved the problem.
Ive got this problem as we speak.A colegue has recently rebuilt the transmission,new plates,seals ect ,but he never renewed the pump??? got one on order.Bet it drives after.
Have seen this issue before. The trans pump looks good inside, but it is bad. Replace it.
