Report "2013 polaris ranger 900 xp. Seems like hen I go over a big bump or hill fast the transmission seems to have a mind of its own and go from limited slip to 4x4 on its own.. I can notice the change by the way the steering feels then I slow down to a stop put in reverse and go slowly then switch back the gear shifter back to high and it seems to go fine! I'm lost how to figure out what is goin on but it is definitely strange. Any idea what is goin on?? Just happens when I go over a mound or big bump"
