Hi I own a towmotor LT 35 it runs great but alas i have had trouble either with the clutch or transmission. I thought it was the clutch but after i tore it down a little i am second guessing myself. I removed he universal between the clutch and tranny and depressed the clutch, and it seem to work ok. I tried turning the tranny and it was a little grindy, but it turned with some hand force. is there any way to establish which is working which is broke and is there any manuals out there
