    Last night when I backed the Duramax into the driveway the Allison shifted very hard and clunked into gear then proceeded to make a zzzzzzzzzz sound for about 1 second almost sounded like tires spinning. The truck has 60,000 miles this is the first year for it plowing and it has been maintained perfectly per H/D service interval charts.

    Any help on possible problem would be greatly appreciated

    Bring it and get it checked if it is still under warranty we have had a few in the shop already.
