Our guide covers 11 model years for the GMC Sierra 1500 (2015–2025) but only 4 for the Chevy Impala (2015–2019), so the GMC Sierra 1500 data reflects a broader range of generations.

Buyer's checklist
What to check before buying a used transmission
- Match the exact transmission ID stamped on the case — the same vehicle can use different units depending on engine, drivetrain, and gear ratio.
- Ask if the transmission was tested before removal. Fluid color matters: red/pink is healthy, brown or burnt-smelling fluid signals internal wear.
- Confirm whether a torque converter (automatic) or clutch kit (manual) is included. Replacing these separately adds $150–$400.
- Check the warranty: reputable yards offer 30–90 days on transmissions. Avoid any with no warranty at all.
