The 2022 Chevy Tahoe and 2022 Chevy Suburban full-size SUVs have received a new 10-speed automatic transmission, GM Authority can confirm.
When equipped with either the 5.3L L84 V8 or 6.2L L87 V8 gasoline engines, the 2022 Chevy Tahoe and Suburban will feature a new version of GM’s 10-speed automatic with controlled overdrive and a Traction Select System with specific tow/haul settings. This transmission is tagged with RPO code MHS and will be standard equipment in all Tahoe and Suburban models with the 5.3L V8 and 6.2L V8.
The older GM 10-speed automatic transmission used in the 2021 model-year Chevy Tahoe and Suburban was tagged with RPO code MQC. This version of the 10-speed will continue to be paired with the Duramax turbo-diesel 3.0L I6 LM2 engine in the SUVs.
GM Authority reached out to General Motors for more information on this new 10-speed transmission, as it carries the exact same description as the outgoing 10-speed. Chevrolet Communications representative Catherine Scales said 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.”
The ability to receive over-the-air updates is important, as this will allow GM to remotely improve, modify, adjust or patch the software that controls the transmission. Most of GM’s newest products run the automaker’s Vehicle Intelligence Platform/Global B architectures, which enable OTA updates for the infotainment system, chassis/powertrain/drivetrain and other important components.
GM Authority went over the changes applied to the 2022 Chevy Tahoe, as well as the 2022 Chevy Suburban, in two separate articles published earlier this month. Some of the more noteworthy changes include the addition of three new exterior colors (Auburn Metallic, Dark Ash Gray Metallic and Evergreen Gray Metallic), as well as the expanded availability of the 6.2L L87 V8 gasoline EcoTec3 engine, which is now available on both RST and Z71 models via the new Sport Performance Package and Off-Road Performance Package.
The 2022 Chevy Tahoe and Suburban are produced at the GM Arlington Assembly plant in Texas.

Way too much electronics. If you want to over engineer something. Start with the lifters.
You ain’t lying. The lifters in the left bank just failed on my ‘21 Tahoe 5.3 RST with 14.5k miles and GM is refusing to do the right thing and replace all the problem lifters in my engine. Numerous service bulletins instruct that the lifters are defective and should be replaced.
I should have never given GM $75k of my hard earned money.
Adam Ibrahim: Have you considered filing a complaint about the non resolution of your lifter failure with the consumer protection department in your state? If you dead end here, there are other avenues you can follow for a resolution. This issue can be fairly solved.
WOW! Tremec in Mexico is on top of things. Love it!
Nothing is mentioned in the article that the new 10 speed automatic transmission is produced in Mexico by Tremec. Give some credit where credit is due. Thanks.
Hopefully this transmission smooth out the bugs and other problems that was with the GM/Ford joint venture. The reviews with Toyota.new 10speed has been great so far
The Tundra feels 'slow' off the line. Pretty safe TM in the factory programing. Like how GM trucks were 10 years ago.
The GM 10spd has always been pretty smooth and intuitive, the Ford on launch was nothing to brag about but has greatly improved since launch, at least with the F150 3.5. Ram's 8 has always been great but that's what you get when you source a ZF unit.
Not a mechanic but just exactly does GM mean “Controlled Overdrive” and a “ Traction select system with specific tow/haul settings”? How is the overdrive or traction and tow/haul settings differ from the 10 speed transmission in the 2021 Tahoe? Is it improved - if so, how, why, what has specifically changed?
I think the MHS variant has been used in Cadillac sedans. What bolts to the 3.0TT V6?
Yea no. Glad I dodged that new tranny on my RST. OTA updates mean we’ll but always screw things up.
Now they’re at it, why not shift pallets behind the wheel ? Or a decent central shift ?
Rear suspension is to low I think GM need to do something. They lost the reputation in the gulf because of it
