Hoping someone can help somewhere, we have a John Deere 4350 quad range, sometimes she seems to be slipping out of gear when she's free running/coasting, just as you come to slow down with no load on engine or box. Only happens every now and again and only when there's minimal strain the drive train.

Local JD dealer can't get hold of workshop manual, any help or advice would be greatly appreciated, even a suggestion of where I could get a hold of the workshop manual, in the states maybe??
