It sat for better than 10 years with a bad motor - just got done rebuilding the motor and now dealing with all the other issues. About half the gears on the trans don't seem to be working right. R2 for sure and some of the forward gears the motor loads down some (not stalling, just not freewheeling) and the tractor moves slowly. I can't tell for sure which forward gears as it's hard to distinguish between a low gear and the creeping behavior I'm seeing. Any thoughts? My guess is it's a sticking valve or something but I don't want to tear things apart randomly trying to find it. The fluid has been changed and the old fluid looked fine - no chips or water. The filter screen was cleaned and main filter changed. When I had the top cover off I saw no rust or evidence of damage inside. The gear that work (R1 and 6/7 that I can tell for sure) the shift is firm and everything feels good. Thanks, ~John [Reply]   [No Email]

That can all be done from the outside and will let you know that you've got a good starting point before you start looking into other possibilities. [Reply]  [No Email]

Overdrive ratios will put more load on the engine than direct drive ratios. I would have said your problem lies between the direct drive clutch and band 1. However, if both 6 and 7 seem to be operating properly, you are operating in DDC (6th) and B1 (7th). I would guess, with no more information than you've been able to provide, that you do have some sticky control valves . . . but that's just a guess. [Reply]  [No Email]
