I have a 2001 polaris magnum 325 4×4 and my idle was set too high and everytime i would go to put it in gear (automatic) it would grind really bad and it finally seemed to strip out the high gear and now it wont go into high gear. Im wondering if i need a whole new transmission or is it something i could replace. Dont know much about these things if anyone could help or give me advise it would be greatly appreciated! Thanks!
