2020 GMC Sierra 1500 Gets Adaptive Cruise Control, Expanded 10-Speed Auto

Available Enhanced ProGrade Trailering Moves from HD to 1500 as Well

May 20, 2019
The 2020 GMC Sierra 1500 is getting slight updates to make it more competitive against the Ford F-150 and Ram 1500, including adaptive cruise control available for the first time on a GM pickup.
One of our complaints about the 2019 Sierra 1500 was its relative lack of driver-assist and safety technologies, even on well-equipped Denali and AT4 models. However, that issue will be rectified on the 2020 Sierra 1500, which adds available camera-based adaptive cruise control that can bring the truck to a complete stop if traffic dictates it.
GMC will offer that feature on the SLT, AT4, and Denali. However, if you ask us, it really should be standard, especially since even the base-model Toyota Tundra offers limited-speed adaptive cruise (which admittedly cannot bring the truck to a complete stop).

2020 GMC Sierra 1500 Combines 5.3L and 10-Speed

Possibly more significant will be expanded availability of the 10-speed automatic gearbox, previously relegated to the 6.2L V-8 only (as well as the 3.0L Duramax I-6 that has yet to appear in dealerships). The transmission will now come standard in the Sierra Denali and Sierra AT4, regardless if the truck has the 6.2L or the 5.3L V-8.
Furthermore, owners of 5.3L-powered, four-wheel-drive trucks in trim levels SLE and above can option the 10-speed instead of the eight-speed. That development marks the first time the big cogswapper will be available with GM's unique Dynamic Fuel Management system. Of course, that trim walk excludes base models with the 5.3L V-8, as well as most two-wheel-drive pickups (it's unclear if the Denali 4x2 will be standard with that 10-speed).

Smarter Towing

Also offered on the 2020 GMC Sierra 1500 will be the upgraded ProGrade Trailering System unveiled earlier this year on the Sierra HD. The tech suite offers 15 different camera views, including the unusual "transparent trailer" mode that links to a trailer-mounted accessory camera to provide an unobstructed view of the rear.

ProGrade Trailering also features an app built into the truck's updated infotainment system, which allows drivers to input trailer profiles, check tire pressures, and access a pre-departure checklist for a safer journey. And the new suite of trailering tech now includes integration with the ASA Electronics iN Command trailer connectivity suite. That means the owner can precondition a compatible trailer's climate controls, adjust lighting, and monitor water and propane levels from the myGMC mobile app.
Updates to the 2020 GMC Sierra 1500 closely follow some of the additions expected for the late-2019 model year. Those include the optional CarbonPro cargo box and that aforementioned 3.0L turbodiesel I-6, which produces 277 hp and a stout 460 lb-ft.
