I need some help guys. I've been researching all day and haven't found anything. Last night I was riding around the house and punched it and when I let off the gas it made a horrible grinding noise. I started messing with it a little and if I go over about 10 mph and let off the gas it makes the sound. It goes into all gears great and has all the power its always had but if I get over 10 and let off the gas it sounds like poo. Any one ever had this problem? Transmission is about 10 month old. About 80 miles. The rear end was replaced then as well. Could it be the one way bearing or no? Any help is appreciated. Thanks.
