Why Buy a 2022 GMC Transmission from Auto Power Source

2022 is the year the GMC half-ton lineup ran two bodies at once. The redesigned truck is listed as New Style and the carryover truck as Classic Style or Sierra 1500 Limited, and both were sold new in the same showroom. That matters here because the gearbox follows the option code, not the nameplate: the 2.7L turbo takes the 8L90, the 3.0L Duramax and the 6.2L take the 10L80, and the 5.3L could leave the plant with either one. We hold all 92 units across both bodies.

On the heavy duty, every Sierra 2500 HD, 3500 HD and Denali HD in this year runs the Allison 10L1000 ten-speed, behind the 6.6L L8T gas V8 as well as the 6.6L Duramax. The listings separate them by fuel and by unit ID — OMEF and OMKF on the Denali HD, Opt MGM on the Sierra HD — and we keep both sides stocked rather than treating the diesel unit as the only one worth carrying.

Because GMC and Chevrolet share these units outright, a gearbox pulled from a Silverado, Tahoe or Suburban is frequently the correct part for a Sierra or Yukon. That widens your options a long way, and it is also why the RPO option code and the drivetrain identify the part rather than the badge on the tailgate. Our ASE-certified technicians read the code off your VIN before anything is reserved.

Every unit here is a used OEM gearbox pulled from a low-mileage donor vehicle, shift-tested through every gear under load, and shipped with free freight to all 50 states, a warranty included, and 30-day money-back cover. You see multi-angle photographs of the actual unit before it leaves the yard, and you approve it before we ship.

Your 2022 GMC Transmission Options: Compared

Most 2022 GMC owners face four real choices when the transmission fails:

← Swipe sideways to see all columns →
Option Cost Reliability Warranty Fitment Match
Used OEM (this collection) $$$ Best Value High — tested Included VIN-matched
New OEM (dealer) $$$$$ 2-4× more High Manufacturer Exact
Aftermarket / Reman $$$$ Varies 6-12 mo May adapt
Junkyard $ Cheapest Unknown None DIY

Tested used OEM hits the sweet spot — same engineering as new, fraction of the cost.

2022 GMC Transmission Buying Guide

5 things to verify before buying a used 2022 GMC transmission:

  1. Option code, not model name. On the 2022 half-ton the 5.3L shipped with either an 8L90 eight-speed or a 10L80 ten-speed. Opt MQE and MHS are the eight-speed; Opt MQB and MHT are the ten-speed. If the listing carries no code, the code on your own vehicle decides.
  2. New Style or Classic Style. 2022 ran the redesigned truck and the carryover truck side by side, badged Sierra 1500 and Sierra 1500 Limited. The two bodies do not share every mount and harness, so settle which one you have before you compare units.
  3. Diesel and gas HD take the same Allison, not the same calibration. Sierra 2500 HD and 3500 HD run the Allison 10L1000 behind both the 6.6L L8T gas V8 and the 6.6L Duramax, but the units are not interchangeable between them. Match the fuel type, and on a Denali HD match the unit ID as well.
  4. 2WD and 4WD are different parts. The listings state 4x2 or 4x4 for a reason: tailshaft housing and transfer-case mating differ. A 4x4 unit will not drop into a 4x2 truck, whatever the engine.
  5. Confirm the match with your own VIN before you order. Send us the VIN off your vehicle and our technicians confirm transmission code, drivetrain and body style against it, then send photographs of the exact unit for your approval before anything ships.

Our ASE-certified technicians verify every one of these points against your VIN before any unit ships.

Frequently Asked Questions

How many 2022 GMC transmissions do you have in stock?
92 tested units right now, covering Sierra 1500 and Sierra 1500 Limited, Sierra Denali 1500, Sierra 2500 HD and 3500 HD, Sierra Denali 2500 and 3500, Yukon, Yukon XL, Acadia, Terrain, Canyon and Savana. The counts on this page are live active stock, not a catalogue listing.
Which transmission is in a 2022 GMC Sierra 1500?
It depends on the engine and the option code. The 2.7L turbo takes the 8L90 eight-speed. The 3.0L Duramax and the 6.2L V8 take the 10L80 ten-speed. The 5.3L took either, so Opt MQE or MHS means the eight-speed and Opt MQB or MHT means the ten-speed. Text us your VIN and we read the code for you.
What is the difference between a 2022 Sierra 1500 and a Sierra 1500 Limited?
The Limited is the carryover body GMC kept building alongside the redesigned 2022 truck, which the listings call New Style. Both were new that year. They are not the same part in every case, so the body style has to be settled before a unit is reserved.
Do 2022 GMC Sierra HD trucks all use the Allison?
Yes — the 2022 Sierra 2500 HD, 3500 HD and the Denali HD versions all run the Allison 10L1000 ten-speed, behind the 6.6L L8T gas V8 as well as the 6.6L Duramax. The gas and diesel units are not interchangeable, and the Denali HD listings carry unit IDs OMEF and OMKF to separate them.
Will a Chevrolet transmission fit my 2022 GMC?
Very often, yes. GMC and Chevrolet share these units outright, so a 10L80 from a Silverado or Tahoe is frequently the correct part for a Sierra or Yukon. What has to match is the RPO option code, the engine and the drivetrain — not the badge. We check all three against your VIN.
What transmission is in a 2022 GMC Terrain or Acadia?
The Acadia 3.6L V6 uses the 9T65 nine-speed and the 2.0L turbo uses the 9T50. The Terrain listings carry no engine, and GM used more than one nine-speed on that line, so we confirm the unit from your VIN rather than guessing from the trim.
What does the warranty cover and how long does shipping take?
Every unit ships with a warranty included and 30-day money-back cover, and freight is free to all 50 states. Most units leave the yard within one to three business days of your approval; transit is typically three to seven business days depending on your state.
How do I get a quote for a 2022 GMC transmission?
Text your VIN to +1-307-441-5554, call 1-877-313-8995, or email info@autopowersource.com. You get matched options with photographs of the actual units, usually within minutes during business hours.

Our 6-Step Inspection & Shipping Process

Every 2022 GMC transmission we ship has been through these six steps:

1. VIN-Matching
We match the donor VIN to your VIN to confirm transmission code, drivetrain, and 2WD/4WD configuration.
2. Tested & Verified
ASE-certified technicians Shift-Test every gear under load. Units are checked for clean engagement, no slipping, no abnormal noises.
3. Noise & Smoke Verification
Units are run to verify normal mechanical sound and clean operation — catches internal wear static tests miss.

Every accessible component is inspected: bell housing, output shaft, solenoid pack, cooler lines, sensor harnesses.
5. Photograph & Catalog
Multi-angle photos sent to you BEFORE we ship for your approval.
6. Palletize & Ship
Strapped on a heavy-duty wooden pallet, shipped via freight at no charge.

Before any transmission leaves our warehouse, we send you multi-angle photographs. You approve.
