How to Reset the Shifting Solenoid on a Chevy S10by Kyle Sanstrom
The shifting solenoid on a Chevrolet S-10 pick-up is designed to regulate when the transmission shifts. This solenoid is part of the electronic transmission control system, and is controlled by the powertrain control module, or PCM. The PCM actuates the shifting solenoid when it determines that an upshift or downshift is required. When the PCM senses a problem with the solenoid or one if its related components it stores a trouble code in its memory and illuminates the "service vehicle" light. When the codes are cleared from the PCM the solenoid is automatically reset.
Shift the truck's transmission into first gear (manual) or park (automatic). Turn off the engine and set the parking brake.
Turn the ignition back to the "ON" position but don't re-start it. Connect an automotive scan tool to the vehicle's diagnostic data port located underneath dashboard on the driver's side.
Power on the scan tool and select "PCM" from the main menu. Select "Transmission" from the PCM sub menu. Select "Clear all current and stored DTCs." DTC is an acronym for "Diagnostic Trouble Code."
Disconnect the can tool from the vehicle and start the engine. Verify that the "service vehicle" light is not on.
- Automotive scan tools are designed to communicate with the computers in cars and trucks. They are small, hand-held computers that can be transported from vehicle to vehicle. They are available from auto parts stores and tool retailers, including online tool websites.
