Lowell said:I always use the tow/haul mode when towing my TT. It reduces the constant shifting and is easier on the transmission. The motor companies put them on trucks for a reason. Why not use it?
Gizmo said:Are you sure you are not confusing Tow/Haul with a diesel engine brake? To the OP, I see no reason not to and I always engage my tow haul mode unless on a long flat road which is rare driving mostly in the west. When steep hills and mountainous terrain is involved engaging it will help towing performance and save your transmission.
garyb1st said:Gizmo, I believe it simply causes the transmission to down shift when braking. I don't know what an engine brake feels like. With the tow haul, you can actually feel the down shift with increased engine rpms. When accelerating, it actually upshifts if still engaged.
