The 2017 Chevy Silverado 1500 did not use a single transmission across all configurations. In short, gas engines typically paired with a six- or eight-speed automatic, while the turbodiesel option used a ten-speed automatic. The exact transmission depends on the engine and drivetrain chosen.
Below is a detailed look at how the transmission choices break down by engine in the 2017 Silverado 1500 lineup, reflecting common configurations for that model year.
Transmission options by engine
4.3L V6
The 4.3L V6 option typically paired with a six-speed automatic transmission.
- Six-speed automatic (Hydra-Matic 6L50/6L80 family)
In practice, buyers choosing the 4.3L V6 could expect a six-speed automatic as the standard pairing for this engine configuration.
5.3L V8
The 5.3L V8 commonly used an eight-speed automatic transmission.
- Eight-speed automatic (Hydra-Matic 8L90 family)
For many trims and drivetrain setups, the 5.3L V8 was paired with an eight-speed automatic, offering smoother shifting and better efficiency than earlier six-speed designs.
6.2L V8
- Eight-speed automatic (Hydra-Matic 8L90 family)
Performance-oriented and higher-torque variants of the 6.2L V8 typically used the eight-speed setup available on the 2017 Silverado 1500 lineup.
3.0L Duramax Diesel
- Ten-speed automatic (Hydra-Matic 10L80 family)
Diesel-powered configurations in 2017 leaned on a ten-speed unit to optimize torque delivery and fuel economy.
Summary
In 2017, the Chevrolet Silverado 1500 offered multiple transmissions depending on the engine choice. The standard 4.3L V6 typically used a six-speed automatic, the 5.3L and 6.2L V8 engines commonly used an eight-speed automatic, and the 3.0L Duramax diesel used a ten-speed automatic. Always verify the exact drivetrain and option package for a given truck, as transmission availability can vary by trim and production date.
