I have a 580C backhoe it goes fine bin reverse but when you put it in forward it goes alitle then stops, if you shut engine off an start again it will move forward then stop. if you put the power shuttle lever in neuutral it will roll back so its not stuck in reverse. Has anyone had this issue? and if so what should I look for
Crawl under there, engine off and machine secured, and make sure the linkage is fully engaging the lever at the Shuttle all the way when it's put into forward first. If that's good, then it sounds like the forward clutch pack in the shuttle has finally given up, as it gets all the abuse from driving, loading and pulling things. You'll want to also replace the Torque Converter alone with doing the Shuttle rebuild.
Is it 2 or 4 wheel drive? Make a big difference.
Being a 580C, pretty safe bet it's not a 4wd.
OK, I was not sure all Cs were 2 WD. So.... Borg Warner shuttle right? Then I would think the forward clutch pack is shot (assuming linkage is right), torque converter would be working if going into reverse.
