Just curious, could you use tow mode for going down a steep grade or exhaust brakes?
I see this about that truck:
"The 2019 Chevrolet Silverado 3500 HD uses a six-speed automatic transmission with tow/haul mode and Auto Grade Braking to reduce the amount of conventional braking needed while towing or driving downhill."
My 2003 does not have Auto Grade Braking so can't say if it is useful.
OK more confusion! It is mixed up with Tow/Haul but you have to read all this in detail. meanwhile it says to activate it you need to leave your foot down---so that gets mixed up with my earlier question about braking (now cleared up, thanks all! ) except for Auto Grade Braking maybe. :(
"For grade braking to activate it requires the driver to apply steady brake pedal pressure to maintain desired speed while driving on a downhill grade. The vehicle’s modules monitor the amount of brake pedal apply, vehicle deceleration rates, and other factors to determine if normal mode powertrain grade braking is necessary"
