are all of the 08-11 rzr transmissions the same. May need a new tranny and don't know if they are all interchangeable or not? very difficult to shift lever with shifter cable off even with big channel locks. someone mentioned the detent ball and spring can be removed, haven't tried yet, but that is next. I also saw someone mention of an upgraded clutch shaft assembly in the tranny. could that be it, did popo have a problem and need to go to this upgrade? searching for any ideas. last time out could not get to L or Hi after going to reverse, had to drive in reverse back to camp. finally got to hi after working shift lever(very hard/tight) with big ass channel locks, sounds like something internal, but once in a gear, that gear works fine. Any ideas?
