The 2023 Chevy Colorado ushers in a fresh third generation for the pickup nameplate, making splashdown with a long list of changes and updates over the preceding 2022 model year. Among these is a new eight-speed automatic transmission, as detailed here.
To be specific, the 2023 Chevy Colorado will feature the new-generation Hydra-Matic 8L90 eight-speed automatic transmission. This new auto box replaces the GM six-speed 6L50 automatic previously matched to the the naturally aspirated 2.5L I4 LCV gasoline engine and 2.8L I4 LWN turbodiesel Duramax engine, as well as the GM eight-speed 8L45 automatic transmission previously matched to the naturally aspirated 3.6L V6 LGZ gasoline engine. For the sake of clarity, we should mention that this new 8L90 transmission differs from the “old” GM eight-speed 8L90 automatic transmission matched to the turbocharged 2.7L I4 L3B gasoline engine in the current Chevy Silverado 1500.
As some GM Authority readers will no doubt recall, the “old” GM eight-speed 8L90 automatic transmission has seen its fair share of problems over the years, being the subject of several lawsuits and TSB fixes. Back in 2019, GM Authority even opined that the 8L90 needs to go away as soon as possible.
During a recent Q&A session with media, GM was asked why it did not equip the 2023 Chevy Colorado with the GM 10-speed automatic transmission, rather than updating the 8L90 eight-speed, given the latter’s history.
“Our new-generation eight-speed will be launching in this truck and we’re really proud of it,” GM responded. “To be very honest, the eight-speed is all about the torque band on the engine, so its got a super raw torque band. And with that, we don’t need as many gear ratios, so the eight-speed matches perfectly with the engine and in this application. It’s an all-new transmission and it’s going to shift fast, smooth, precise, and we’re really proud of this, and I think our customers will be as well.”
As a reminder, the 2023 Chevy Colorado features just one powerplant option, the turbocharged 2.7L I4 L3B, which is available in three states of tune – 2.7L Turbo (237 horsepower and 259 pound-feet of torque), 2.7L Turbo Plus (310 horsepower and 390 pound-feet of torque), and 2.7 Turbo High-Output (310 horsepower, 430 pound-feet of torque). Availability depends on the trim level selected.
The 2023 Chevy Colorado will launch in the first half of the 2023 calendar year. Production will take place at the GM Wentzville plant in Missouri.
