I have an 2002 dura max, and was wondering if anybody had this problem.
I was going down a fairly steep grade, in tow haul mode, the Allison kicked down a gear and the motor was turning about 3500 rpm and holding back the rig as it should.. Then for no know reason the Allison started free wheeling. I had to give it a little gas to get it to re-engage. Did this twice on the way home.
Anybody have any suggestion.
Any help wouuld be appreciated
