It has just recently started to "slip out of gear" or that's at least what it sounds like. I have taken the entire tranny out and pull the case apart thinking that it might be a stripped gear, but I didn't see any gears missing teeth. I have taken the slipper clutch apart and cleaned it and tried to adjust it but I have had no luck. It seems to do it the most when shifting from 1st to 2nd. It also does it when the engine revs high. I have no idea what to do.
