The 2017 GMC Yukon uses a six‑speed automatic transmission (Hydra‑Matic 6L80) across most trims, paired with the 5.3‑liter or 6.2‑liter V8 engines. There is no 8‑speed option for this model year.
Powertrain overview
The Yukon’s 2017 model year offered two gasoline V8 engines, both designed to pair with GM’s automatic transmission family. The choices affected power output and available trims, but the transmission remained the same for the year.
Engines available
The following engines were available for the 2017 Yukon and were paired with the same six‑speed automatic transmission in that year.
- 5.3‑liter V8 (approximately 355 hp and 383 lb‑ft of torque) — standard on base Yukon models; paired with the Hydra‑Matic 6L80 six‑speed automatic.
- 6.2‑liter V8 (approximately 420 hp and 460 lb‑ft of torque) — available on higher trims such as Denali; paired with the same six‑speed automatic transmission.
In short, both engine options used the six‑speed automatic transmission, and the Yukon did not offer an eight‑speed option for 2017.
Transmission specifics
The Yukon’s 2017 transmission is the Hydra‑Matic 6L80, a six‑speed automatic designed to handle V8 power in GM’s full‑size SUV lineup. This configuration applied across most drivetrains and did not include an eight‑speed option in that model year.
- Hydra‑Matic 6L80 six‑speed automatic transmission — standard pairing for the 5.3L and 6.2L Yukon engines in 2017.
- No 8‑speed option for the 2017 Yukon; a later‑year update would be required to access different transmission options.
These transmission choices contributed to a familiar driving feel across Yukon trims, prioritizing reliability and towing capability typical of GM’s full‑size SUVs.
Summary
The 2017 GMC Yukon is powered by two V8 options (5.3L and 6.2L) that both use the Hydra‑Matic 6L80 six‑speed automatic transmission. An eight‑speed transmission was not offered in this model year, making the six‑speed automatic a defining feature of the 2017 Yukon’s drivetrain.
