I have a coleman 400 utv that I use for hay for cows. It grinds in reverse bad. How can I get part to fix this problem. Currently only can use in forward. Adjusted cable bunch of times. It either grinds in forward or reverse. So I adjusted it for forward use. So aggravating. Wasted $10,000.00 . Should have spent $3,500.00 more dollars and bought a Honda,Kawasaki, Yamaha, Kubota, kioti,etc. . Please advice is needed.
