Where is the tccm on your Chevy S-10?

There's no standard component called a "TCCM" (Transmission Control Control Module) in a Chevy S-10. Chevy S-10s, depending on the year and transmission type, might have a TCM (Transmission Control Module). This is the more common term. The location varies by year and model. It's usually found either under the dash, or more commonly, under the vehicle near the transmission itself. You'll need to consult your vehicle's repair manual or a wiring diagram specific to your year and model S-10 to pinpoint its exact location.
