What transmission is in a 87 S-10?
Most 1987 S-10 pickups came with either a three-speed automatic or a manual gearbox, with the exact option depending on the engine and trim level. The model year offered a mix of manual and automatic transmissions rather than a single standard setup.
Manual transmissions in the 1987 S-10
Manual gearboxes were available for enthusiasts and certain configurations, especially on the base inline-four and some V6 combinations. Availability varied by drivetrain and market, so not every 1987 S-10 had a manual transmission.
- Five-speed manual transmission offered on select models and engine configurations, typically paired with two-wheel drive variants.
- Four-speed manual transmission available on some 4x4 configurations and higher-trim setups.
When in doubt, the best way to confirm the exact manual box is to check the shift pattern on the stick, inspect the bellhousing area, or review the vehicle’s original build sheet (RPO codes) and glovebox tag.
Automatic transmissions in the 1987 S-10
Automatic transmissions were common across many engine choices, with different three- and four-speed options depending on the configuration. The choice of automatic tended to follow engine and drivetrain compatibility.
- Three-speed automatic transmissions were the most widely installed on the 1987 S-10 across many engines, including the inline-four and V6 options.
- Four-speed automatic transmissions were available on select configurations, though less common than the three-speed option.
To know the exact automatic transmission in a specific truck, verify the vehicle’s RPO codes, refer to the original dealer window sticker, or consult the service manual for the exact build date and package.
How to verify the exact transmission on your 1987 S-10
If you want to pinpoint the exact transmission in a particular 1987 S-10, follow these steps:
- Check the glovebox door for the VIN and RPO (Regular Production Option) sticker, which lists the original transmission code or related options.
- Inspect the transmission pan and casing for identifying stamps or model numbers that can be cross-referenced with GM guides from the era.
- Review the owner’s manual or the original build sheet to confirm the factory-installed transmission option.
- Contact a Chevrolet dealer or a vintage GM parts specialist with the VIN for an authoritative lookup.
Knowing the exact transmission helps with parts compatibility, valve-body timing, and known service bulletins that may apply to your 1987 S-10.
Summary
The 1987 Chevrolet S-10 did not use a single transmission; it offered both manual and automatic options that depended on the engine, drivetrain, and trim level. Manual options included likely 4- and 5-speed configurations on certain models, while automatic offerings typically included a three-speed unit with occasional four-speed variants. For precise identification, check the RPO codes, build sheet, or the transmission itself.
