Borrowed a neighbor's 530 payloader to move some dirt. It worked great for most of the job, but suddenly it quit moving, any gear, any direction. Fiddled with it for a bit and finally got it to move in Reverse, 3. Parked and let sit for a while.
Checked and filled transmission oil. Periodically would move, sometimes in forward, sometimes in reverse. As outside temp fell, if it was REALLY cold, I could get it to go forward and reverse, but as the machine warmed up, it would go back to one or no direction, usually 3rd gear only.
Other hydraulics work fine. Replaced transmission oil filter.
I'm at a loss on what (and where) to check next. Any expert opinions?
