When equipped with either the 5.3L L84 V8 or 6.2L L87 V8 gasoline engines, the 2022 GMC Yukon and Yukon XL will utilize a new version of GM’s 10-speed automatic with controlled overdrive and a Traction Select System with specific tow/haul settings. This transmission, which is tagged with RPO code MHS, will be standard equipment in all Yukon and Yukon XL models with the 5.3L V8 and 6.2L V8. This exact same change was also applied to the 2022 Chevy Tahoe and Suburban, as outlined in this article published earlier this week.
Just as with the 2022 Chevy Tahoe and Suburban, the previous version of the GM 10-speed automatic will continue to be offered on the GMC Yukon and Yukon XL, but it will only come paired with the Duramax turbo-diesel 3.0L I6 LM2 engine in the SUVs. This version of the transmission, which was used in both gasoline and diesel versions of GM’s full-size SUVs for 2021, is tagged with RPO code MQC.
Chevrolet Communications representative Catherine Scales told GM Authority that this version of the transmission “allows our manufacturing and dealer teams to more easily align the specific calibration needed for the transmission and can enable OTA updates in the future.” While Scales was commenting specifically on the use of this transmission in the Tahoe and Suburban, this same reasoning applied to the Yukon and Yukon XL. The majority of GM’s latest products run its connected Vehicle Intelligence Platform/Global B architectures, which enable OTA updates for the infotainment system, chassis/powertrain/drivetrain and other important components to ensure optimal operation over the lifetime of the vehicle.
GM has applied small changes to the GMC Yukon for the 2022 model year. For starters, the 2022 Yukon will do away with the Dark Sky Metallic and Smokey Quartz Metallic exterior colors and will add Redwood Metallic to the order books. The SUV will also now come standard Lane Keep Assist with Lane Departure Warning and a new 12-inch Multi-Color Enhanced Driver Information Center as standard. There’s also a new Denali Black Package for the Denali trim level, while the off-road focused GMC Yukon AT4 will now be available with the 6.2L L87 V8 engine.
GM’s full-size SUVs are produced at the GM Arlington Assembly plant in Texas.
