Shift Solenoid C Malfunction
Meaning
The transmission control module has detected a fault in the shift solenoid C (SSC) circuit. The solenoid does not respond correctly to the command signal, causing abnormal behaviour in the gears governed by SSC.
Common causes
- Internally defective SSC solenoid (open or shorted coil)
- Short to ground or short to battery in the SSC control wire
- Open circuit in wiring to SSC
- Oxidised or loose connectors on the transmission housing
- Valve body obstruction in the SSC solenoid channel
- Internal TCM fault
Symptoms
- Check engine or transmission warning light on
- Transmission fails to engage or engages abnormally in SSC-controlled gears
- Transmission in limp mode
- Harsh or erratic gear shifts
- Slipping in certain gears
Severity
High: the SSC circuit fault impairs gear selection and can cause progressive clutch damage.
What to do
- Check ATF level and condition
- Measure SSC solenoid resistance with a multimeter (typically 10–15 Ω)
- Check supply voltage and command signal at the SSC connector
- Inspect wiring for shorts or open circuits
- Replace SSC solenoid if outside specification or valve body if obstructed
