I have a 2007 650 Outlander Max. Often times when I try to shift, and it doesn’t matter to which gear, it is very hard to move the lever. I play with it, starting and stopping the engine, etc. until it moves more smoothly because I’m reluctant to use the force it would take to use pressure. If you ever parked an automatic transmission car on a steep hill witnout using the parking brake, that’s what it’s like. Pushing the ATV back and forth doesn’t do any thing.
I searched this topic and found numerous threads that said linkage wasn’t a likely culprit but that gearbox oil and a bearing might be. Am I having the same hard shifting issue as those guys? It doesn’t happen all the time but it is frequent and I worry about breaking something.
