The Chevy S-10's transmission depends on the year, engine and drivetrain, but the two most common setups are a 4-speed automatic (GM 4L60-E) and a 5-speed manual (NV1500). Some early models used older automatic boxes as well. Check your exact vehicle’s VIN or build sheet to confirm the spec for your truck.
Automatic transmissions used in the S-10
The following outlines the automatic options that appeared on S-10/Sonoma models over the years, highlighting which engines they typically paired with and when they were common.
- GM 4L60-E 4-speed automatic: The workhorse transmission for most late-1980s through early-2000s S-10s. It’s an electronically controlled overdrive unit that typically paired with the 2.2L inline-four and the 4.3L V6, and was used across 2WD and 4WD configurations.
Many S-10s were equipped with this 4L60-E automatic; in 4x4 models it often integrated with the transfer case and low-range gearing as part of the drivetrain.
Manual transmissions used in the S-10
For buyers who preferred a manual, the S-10 offered a 5-speed manual in many trims and years, most commonly the NV1500 family box behind the 2.2L and 4.3L engines. This configuration became a standard option on many late-1990s and early-2000s trucks, providing added gear choices for highway cruising and towing.
- New Venture Gear NV1500 5-speed manual: A widely installed 5-speed manual in 1990s-2000s S-10/Sonoma models, commonly paired with the 2.2L I4 and the 4.3L V6. It’s known for being relatively robust with proper maintenance.
Beyond the NV1500, early S-10s sometimes used other manual or automatic boxes, but the NV1500 is the best-known and most common manual option for the late-1990s to early-2000s trucks.
How to identify your S10’s transmission
To confirm which transmission your S-10 has, inspect the transmission pan for a model stamp or badge (e.g., 4L60-E). If you have a manual, you’ll notice an H-pattern shifter with a dedicated label or stamping on the bell housing or midsection. For precise confirmation, pull the vehicle identification number (VIN) and consult the RPO/build sheet or a service manual specific to your truck’s year and engine.
Summary
The Chevy S-10’s transmission lineup varies by year and configuration, but the two most prevalent setups are the 4-speed automatic GM 4L60-E and the 5-speed manual NV1500. Early models used older automatics, but the 4L60-E and NV1500 have been the standard references for most S-10s built from the late 1980s through 2004. For certainty, verify your exact vehicle’s spec via the VIN/build sheet or the transmission itself.
