I have a 1990 Yamaha big bear 350 4x4 and when I am driving in low gears and switch it to high the transmission slips into false neutral no matter what gear I am in. If I switch back to low it is in gear and switch back it may stay in gear or go back to a false neutral. I have to try 5 or 6 times switching back from low to high until it stays in gear.
Any suggestions on how to repair this???????????
