The current Chevrolet Blazer uses GM’s Hydra-Matic 9-speed automatic transmission, paired with either a 2.0-liter turbocharged four-cylinder or a 3.6-liter V6, with front-wheel drive or all-wheel drive depending on the trim.
The Blazer’s transmission landscape has evolved since its 2019 reboot. This article explains the transmission used today, how it pairs with the available engines and drivetrains, and what that means for performance and maintenance, while also noting older Blazer generations.
Current generation transmission: the Hydra-Matic 9-speed automatic
The modern Blazer relies on GM’s Hydra-Matic 9-speed automatic transmission for all trims that use an automatic gearbox. It is designed to deliver smooth shifts, responsive acceleration, and improved fuel economy across a range of driving conditions. The transmission is paired with both engine options and with either front-wheel drive or all-wheel drive, depending on the configuration.
Engine options that pair with the 9-speed
The Blazer is offered with two main engines, both mated to the same 9-speed automatic:
- 2.0-liter turbocharged inline-4 engine, paired with the 9-speed automatic and available AWD.
- 3.6-liter V6 engine, paired with the 9-speed automatic and available AWD.
With either engine, the 9-speed automatic enables smooth gear changes and supports front-wheel drive or all-wheel drive setups, depending on the model year and trim level.
Older Blazer generations: transmission options by era
Prior to the 2019 reboot, the Blazer nameplate covered several generations with a variety of transmissions. Early models often used GM automatic transmissions, and later generations commonly employed 4-speed and 6-speed automatics. Some years and trims offered manual configurations in 4x4 setups. The exact transmission depended on the year, market, and trim.
Notes on maintenance and reliability
GM’s Hydra-Matic 9-speed automatic is designed for durability, but following the owner’s manual service recommendations and monitoring transmission fluid levels is important. If you notice slipping, harsh shifts, or delayed engagement, a professional inspection is advised.
Summary
In the current Chevrolet Blazer, the standard transmission is the Hydra-Matic 9-speed automatic, paired with either a 2.0L turbo or a 3.6L V6, and available with front-wheel drive or all-wheel drive. Older Blazer models used a range of GM automatics or manual options depending on the era. If you’re shopping for a Blazer, confirm the specific drivetrain configuration to know exactly which transmission is installed.
