* Higher Shift Points: The transmission will hold gears longer at higher RPMs, providing more power for climbing hills or accelerating with a heavy load. This prevents excessive downshifting.
* Faster Downshifts: Downshifts will occur more quickly, improving engine braking on descents. This helps control speed and reduces strain on the brakes.
* Improved Throttle Response: The throttle will become more responsive, allowing for better control when towing or hauling.
In essence, it makes the truck more powerful and easier to control under heavy loads, preventing excessive stress on the engine and transmission. You'll want to engage tow/haul mode when towing a trailer or hauling a significant amount of cargo in the truck bed. Otherwise, it's generally best to leave it off for optimal fuel economy and smoother driving.
