Running a great 5030 that recently started sticking in reverse. It'll run fine awhile sometimes all day and other times every time you go into reverse it gets stuck. I can slip the clutch a little and sometimes it'll pop right out but other times it takes 2-5 mins to get it out. Doesn't seem to be any specific reason(hilly, flat, loaded or empty) just when it feels like it i guess. One other odd thing, when it's stuck you can pull both the high/low and the gear into neutral but if you apply pressure to the shuttle it's still catching the gear. Enough infact if you push hard enough it'll stall the tractor. Clutch seems fine with free play and this just started out of the blue. Any help other than a $4200 synchronizer and a complete disassembly?
