Coming back to an Avalanche from a 14 Silverado I checked out the trans yesterday and was able to get the message in the DIC, Grade Braking disabled... Haven't seen any post on this here so I want to share that by doing so (holding in the tow/haul button for 5 seconds) may help with fuel mileage slightly and provide smoother downshifts.
Grade braking uses the transmission to slow down the truck.
Many have complained on another forum I belong to on the Silverado's of clunky downshifts when slowing for a stop.
Try it and post your findings.
