I have a TR 89 that is giving me some trouble. It won't go into 3rd or 4th gear in the transmission. Anyone familiar knows the TRs and the manual gear selector and how it can be a problem. I've tried with the engine off,on,getting the hydro to spin slightly and trying to put in gear no grinding no nothing just wont go. Now I can get in 1st or 2nd gear but no 3rd or 4th. I'm thinking shifting fork. Tried unhooking the cables and doing it on the transmission, no luck. So I think I may have to drop the tranny. I've been told to make sure i drive it up on blocks to get enough clearance underneath, any other suggestions or something else to look at first. Even if i could get 3rd or 4th I would be happy, but I know thats not a permanent fix. Any help, I mean any would be appreciated.
