Komatsu FG70T-6:
Losing trans pressure

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.

Have seen this issue before. The trans pump looks good inside, but it is bad. Replace it.
