04 2500HD, Reg Cab D/A. Company truck and the foreman states that when he's coming down a steep grade at about 60-62 MPH the tranny will down shift. Is this normal? Any suggestions?

Part of the beauty of the Allison. tbone1227 08-31-2004, 11:08 AM thats what they consider grade braking - right ? and like eric said, what a beautiful thing we have under us eh _nar_ 08-31-2004, 11:21 PM It's really helpfull when pulling a trailer without trailer brakes.
