2020 Colorado Transmission Fitments In Stock
All 4 in-stock 2020 Colorado transmission fitments, one card per build. Two variables, two values each — displacement and driven axles — which makes this the most straightforward matching job on the 2020 Chevy shelf. Every unit is still VIN-matched at the order step, so nothing rests on you reading the sticker correctly.

Why Buy a 2020 Chevy Colorado Transmission from Auto Power Source
Mid-size trucks get bought for work and then actually worked, so donor selection matters more here than the low price tag suggests. Nothing on this page came off a gravel lot. Each unit was pulled from a low-mileage 2020 Colorado, logged against that truck's VIN the day it came in, and stored indoors until it sold — original OEM, never rebuilt, never reshelled. Our ASE-certified technicians clear each one on the bench before it is offered, and any unit that hunts or flares under load goes back rather than out.
What makes the Colorado unusually easy to get right: the gearbox is the constant, not the variable. All four units we stock are the same six-speed automatic carrying option code MYB — no second gear count, no manual, no alternate code to trip over. That leaves exactly two things to establish, your displacement and whether the truck drives two wheels or four, and your VIN answers both in one read. Send it to us and we will confirm your fitment before you commit to anything.

2020 Colorado Transmission Buying Guide
-
Start with displacement. We hold the 2.5L and the 2.8L for this truck. The VIN settles it, and it is the first fork in the road on every Colorado order.
-
Then say 4x2 or 4x4. Both displacements are stocked either way, so this is a real choice rather than a formality — and it is the one customers most often guess at.
-
You do not need to hunt for a gear code. Every Colorado transmission we stock is the same six-speed automatic (opt MYB). Unlike some other 2020 Chevy trucks, there is no second gear count to rule out here.
-
Confirm mounting and cooler-line routing against your truck. Brackets, harness connectors and cooler-line runs are what turn a technically correct unit into a bolt-in one, and we check them against your VIN rather than assuming.
-
Ask us for the donor VIN. We release it on request for any Colorado transmission in stock, so you can check the mileage and history yourself instead of taking our word for it.
Our ASE-certified technicians verify every one of these points against your VIN before any transmission ships.

Frequently Asked Questions
What is the warranty on a 2020 Colorado transmission?
Up to 3 years, depending on the specific unit. The exact term is shown on each product page.
What does shift-tested mean?
ASE-certified technicians run the unit through all six gears under load and check for slip, flare and harsh engagement before it is cleared for sale.
How long until delivery?
Prep and ship time is 3-5 business days. Transit time is 2-3 business days via freight carrier after dispatch.
Can I see photos before I buy?
Yes. Multi-angle photos of the actual unit are sent before payment.
Do I need my VIN?
It is the fastest route. Your Colorado came as a 2.5L or a 2.8L, in 4x2 or 4x4, and the VIN pins both down in a single read.
What if I do not approve the photos?
Every dollar back — no restocking fees, no return freight charges.
Why is this cheaper than a dealer replacement?
It is used OEM out of a low-mileage donor Colorado — the same Chevy engineering, minus the new-part markup.
When can I reach customer service?
24 hours a day, Monday through Saturday.

Our 6-Step Inspection & Shipping Process
Every 2020 Colorado transmission we ship has been through these six steps:
1. VIN-MatchingWe read your VIN to confirm the displacement and whether the truck is 4x2 or 4x4 before anything is pulled from the rack.
2. Tested & VerifiedASE-certified technicians shift-test the unit through all six gears and watch for slip, flare and harsh engagement.
3. Shift & Road VerificationRun under load, because a mid-size truck gearbox that behaves on a static bench can still hunt once weight is on it.
4. Visual InspectionCase, bellhousing, pan, cooler lines, harness connectors and every mounting point get eyes on them.
5. Photograph & CatalogMulti-angle photos go to you BEFORE we ship, for your approval.
6. Palletize & ShipStrapped to a heavy-duty wooden pallet and sent by freight at no charge.
