I just purchased a 1974 case 580b with the diesel motor and the powershuttle transmission. was told buy the owner that they had rebuilt the powershuttle and it would not move, so i go it home and soon realized that the powershuttle was full of gear oil and mixed with water probly from it sitting for so long. so i drained it put in some new fluid from tractor supply.. said it was compatible with transmissions that use case tch it moved in reverse a pretty good then slowly started to slow down and no forward at all so i hav since drained and refilled about 5 times now and it moves normaly in forward Works great, but no reverse now i hav gauges on all 3 test ports according to my manual everything looks great besides clutch pressures in forwad reved up i got about 180 psi witch is normal and it works great in forward but reverse im only getting about a 100 psi and it wont move in reverse i can lift the tires off the ground with the out riggers and the tires will spin but cant move its own weight in reverse wich is strange to me because reverse was the only thing that worked when i first got it going if any body has any input or experience with somthing like this anything will help befor i go broke buying fuild for this thing if its not going to really fix it lol thank you
