There are two different trucks in this list and nothing crosses between them. The 2004–2012 Colorado is one vehicle; the 2015-onward Colorado is a new truck on a new platform. The listings show the break plainly — there is nothing for 2013 or 2014, the two years the Colorado was not built. Establish which truck you have before anything else, because a transmission from one will not serve the other.
These listings run from 2004 to 2023 and include both automatics and manuals, though the manuals stop after 2019. Colorado parts are shared with the GMC Canyon, so the pool is wider than the model name suggests.

How to pick the right one
Settle the generation first, then the option code. On the 2015-onward truck the option code is the decision: MYB is the six-speed and M5T is the eight-speed, and from 2018 a 3.6 could have either, so the year does not tell you which. N8D is the manual. One trap is worth spelling out. A 2.8 litre Colorado from 2004 and a 2.8 litre Colorado from 2017 share a displacement figure and nothing else — the early one is the Vortec petrol four, the later one is the Duramax diesel, and their transmissions are unrelated. The generation resolves it. On the first-generation truck, match the engine and then the driveline, since 4x2 and 4x4 are listed apart. For 2023 the listings are identified by the eighth VIN character rather than by a displacement.
What usually goes wrong on these transmissions
On the first-generation truck the four-speed automatic is the usual reason for a replacement, and the usual symptom is a slip or a loss of the upper gears under load. Before buying, rule out the cheaper causes: a failing shift solenoid or a wiring fault at the connector produces similar behaviour and costs far less to put right. On the second-generation six-speed the common complaints are a shudder from the torque converter clutch and harsh low-speed shifts, which often trace to fluid condition rather than hard parts. The eight-speed from 2018 has its own documented shudder complaint, again fluid related in many cases. None of that is a reason to skip a replacement if the unit is genuinely finished, but it is a reason to diagnose properly first. Each listing states its condition and the mileage options.

Chevrolet Colorado used transmissions — frequently asked questions
Why is there nothing listed for 2013 or 2014?
The Colorado was not built for those two model years. Production of the first-generation truck ended after 2012 and the new truck arrived for 2015, which is why the listings jump across the gap.
What is the difference between option MYB and option M5T?
MYB is the six-speed automatic and M5T is the eight-speed. From 2018 a 3.6 litre Colorado could be built with either, so the year alone does not identify which one you need — the option code does.
Is a 2004 2.8L transmission the same as a 2017 2.8L transmission?
No, and this catches people out. The 2004 2.8 is a Vortec petrol four and the 2017 2.8 is a Duramax diesel. They share only the displacement figure, and they belong to different generations of the truck with unrelated transmissions.
Will a GMC Canyon transmission fit a Chevrolet Colorado?
The two trucks are built from the same parts, so a correctly matched Canyon unit of the same generation, engine and option code is the same part. It is worth searching both names.
What comes with a used Chevrolet Colorado transmission?
Each listing states its condition and its mileage options. Fitment is matched to your VIN before the order goes out, every unit carries a written warranty of 6 months, extendable to 3 years, parts only, and freight is free anywhere in the lower 48.
