2001 450 ES Foreman trany/shifter troubles

If it was working when parked a year ago, it cannot be too seriously jammed. I would forcefully rock it back and forth while using the manual shifter to get things loosened up.

Remove the battery cables from the terminals and clean those connections too. If the battery is more than 5 years old, get a new one.

Sounds like you could use a service manual..? Here ya go: TRX450 Foreman

Ths Retro, have manual. Looking for shortcut to service the jamming. Maybe through side to access gears/linkage???

Thx ktriebol. Manual shifter is locked/jammed. Hoped I could advice on a shortcut to access jamming problem. Guessing ES can't do anything, good battery or not, with jammed condition. Have rocked but can't unlock.
