After i came out of a mud hole my four wheeler died. Every since then my four wheeler will not shift. It seems like it is in 2nd gear. I can still drive it but when there is any kind of load on it, it will not pull. When in ESP it shows to be shifting and the celionoid even acts like it is working, but the motor doesnt act like it is going in to a diffrent gear. I herd that there is trouble whith the o-rings in the older models but mine is an 05. NEED HELP
