The 2016 Chevrolet Impala uses a 6-speed automatic transmission. Both engine options pair with this unit, and there is no manual transmission offered for this model year.
In 2016, the Impala offered two engines—the 2.5-liter inline-4 and the 3.6-liter V6—and both were paired with a 6-speed automatic transmission, with front-wheel drive as standard.
Engine options and transmission pairing
The 2016 Impala was built to offer two powertrains, and each used a six-speed automatic transmission. The following outlines the two engine/transmission pairings:
- 2.5-liter inline-4 engine with a 6-speed automatic transmission (front-wheel drive).
- 3.6-liter V6 engine with a 6-speed automatic transmission (front-wheel drive).
Both options deliver smooth shifts and are designed for efficient highway cruising, with no manual gearbox available for this model year.
Transmission details and maintenance
Transmission family
GM's 6-speed automatic transmission family was used across the Impala lineup for 2016. The system is designed to provide reliable shifts and refined performance for both engines. The proper transmission fluid is Dexron VI, and maintenance should follow the owner’s manual guidelines.
What to watch for
As with any used vehicle, be attentive to transmission behavior: smooth engagement when starting from a stop, a consistent shift feel through the gears, and no slipping or shuddering at highway speeds. If any of these occur, have a qualified mechanic inspect the transmission fluid level and condition, and consider a professional diagnostic test.
Summary
The 2016 Chevrolet Impala uses a 6-speed automatic transmission for both available engines (2.5L I-4 and 3.6L V6). There was no manual option, and maintenance revolves around the correct Dexron VI fluid and standard service intervals as outlined in the owner’s manual. This configuration aims to balance efficiency with comfortable, confident performance for a full-size sedan.
