Guys I need some help!! Over the weekend I pulled the CVT off of my 2003 kodiak 400 4x4 to clean and add new grease to it. I got it all put back together and rode it to the end of my driveway and back (about 80 yards) and it made a metal grinding popping noise and now it will not go forward or reverse. I took everything apart and the cvt is still intact. What could have happened?
