I have a 06 arctic cat 400 4x4 auto all was good until I snorkeled it was having idle issues. Ended up taping up the snorkel half way so it would idle but high just so I could use it. I was muddin for about a hour and put it in reverse to get a run a the pit and go to put it in low range the shiftier went to low range and felt normal but when I went to hit the gas it was stuck in reverse not fully but still tried to reverse. Now ive pulled the engine and trans and completely went through it and everything is good. I finally got my jet kit and pilot jets. Another weird thing I noticed is when I reverse and let off the throttle it like locks the back tires??
