Frequently Asked Questions

Does the 700R4 transmission receive full rebuild coverage?

Yes. The 4-speed 700R4 automatic, used widely in S-15 models from the mid-1980s onward, is covered in full. The manual includes TV cable adjustment procedures, clutch pack specifications, governor service, valve body disassembly, and complete torque specifications for reassembly.

Is the GMC S-15 Jimmy included alongside the standard pickup?

Absolutely. Both the S-15 pickup (standard and extended cab) and the S-15 Jimmy SUV are covered. These models share the same S-body platform and powertrain lineup, so all engine, transmission, and chassis procedures apply to both body styles across all trim levels including High Sierra and Sierra Classic.

Are wiring diagrams included for all model years 1982-1993?

Yes. Electrical system documentation spans the entire 1982-1993 production run, covering the charging system, ignition, lighting circuits, instrumentation, and accessories. Circuit diagrams include connector locations and ground point references to support accurate fault diagnosis on any model year.

What format is the manual?

The manual is delivered as a PDF file, downloadable immediately after purchase. It is compatible with any PDF reader on Windows, Mac, Linux, Android, and iOS devices, and individual pages can be printed for use in the garage.
