I have a case 570lxt that will not move forward or reverse I have already taken off the trani control valve assy pulled apart. no sign of broken clips or damage, also the solenoids seem to be working just fine. the tractor will go in forward and reverse but for less than a minute followed by locking up completely help please!
Welcome to HEF jcbeck! This sounds very unusual. When you say the tractor 'locks up' - Does it not roll at all? Is the engine under load when you try to drive?
