I have a JD 2950 and the transmission is starting to slip when your driving. We have already replaced the master cylinder a month ago and had been running good until the other day when it started slipping. We have checked the slave cylinder and there is no sign of a leak and moves about an inch when pushing on the clutch pedal. When I was replacing the seals on the 3pt there were two ball bearings in the bottom of the rear end with no marks or scratches on them the tractor still ran and shifted fine with out them. We didn't think it was a big deal until now, we think they might have come out of something important. Any ideas on fixing this problem would be greatly appreciated. Thanks!
