My 2006 wolverine 450 doesn't want to stay in park. The parking light doesn't come on when placed in park, so it appears it's not engaging the electrical circuit. Anytime I try to place it in park even on a slight grade, the quad just wants to drift away. When it does drift away, I can hear clicking from what sounds like either underneath the middle or back of the quad. Very very rarely does the quad ever shift into park and actually stay there. I think this model might have Park inside the transmission. I'm not familiar at all with how the parking break system works on this model. Any suggestions?
