08 3500 in Tow Haul mode
I have a 08 3500 DRW 6.7L Diesel 160K miles.
I use the truck to haul a 15K lb 5th wheel. When towing I have it in Tow Haul mode. On acceleration it shifts fine. When I decelerate it down shifts kind of hard. If I take the tow haul off when I decelerate it's nice and smooth.
Anyone have this issue? Or what might be going on?
TIA.
