Typically, the 2010 Silverado 1500 uses either a 4-speed automatic (4L60-E) with the V6 and smaller V8s, or a 6-speed automatic (6L80) with the larger V8s.
The exact transmission in your truck depends on the engine and drivetrain. In this article, we break down the common pairings and provide tips to identify which unit your specific truck uses.
Transmission options by engine
Understanding the typical trans-by-engine mapping helps you identify what’s under your hood and what service it may require.
- 4.3L V6 (engine, RPO L35) — 4L60-E four-speed automatic (RWD or 4x2; 4x4 uses the same transmission)
- 4.8L V8 — 4L60-E four-speed automatic
- 5.3L V8 — 6L80 six-speed automatic
- 6.2L V8 — 6L80 six-speed automatic
Bottom line: If your Silverado 1500 is equipped with a V8 larger than about 5.3L, it’s likely the 6L80; smaller engines typically paired with the 4L60-E. Always verify with the glove box code or VIN if you need certainty.
How to identify your exact transmission
To confirm the precise transmission model in your truck, use these steps:
- Look for the transmission model stamped on the side of the transmission housing or on a tag near the bellhousing. Markings will read 4L60-E or 6L80 (and sometimes 6L90 for certain HD configurations).
- Inspect the transmission pan or the exterior pan rail for a model stamp corresponding to the transmission type.
- Check the vehicle’s RPO/option sticker inside the glove box or the build VIN/decode documentation to see which transmission was installed.
- If you’re unsure, provide the VIN to a Chevrolet dealer or use a reputable online VIN decoder to confirm the exact transmission on your exact truck.
Summary
The 2010 Chevy Silverado 1500 offered two main automatic options driven by engine choice: the 4L60-E four-speed automatic for the V6 and smaller V8s, and the 6L80 six-speed automatic for the larger V8s (notably 5.3L and 6.2L). Verification can be done by checking the transmission label, pan stamping, or VIN/RPO information. This helps ensure correct maintenance and parts compatibility.
