'02 rancher transmission prob.

when you say manually, do you mean the emergency tool? Have you checked the clutch adjustment?

Hard to tell but worth checking out. If there aren't any error codes [flashing display] and if it won't come out of 3rd with the tool, and the clutch is adjusted properly, then you're probably looking at taking it to the shop unless you can crack it open yourself, but that's just a guess.
