Re: Tow/Haul Button
On many GM's (the Allison in the pickups and the 4L85 in vans and cutaways) the T/H mode will also raise line pressure in the transmission so the various clutches will apply with more force and slip less, hence the "firm" shift.
HotFr8Recuiter, are you sure you have an Allison in a 1500 and not the new 6L90 GM?
