P0761 is a generic transmission-related diagnostic trouble code (DTC). It indicates that the Powertrain Control Module (PCM) has detected an issue with Shift Solenoid “C” — specifically, that it’s not performing as expected or is stuck in the “off” position.
1. Faulty shift solenoid “C”
2. Dirty or low transmission fluid
3. Internal transmission failure (valve body issue)
4. Wiring problems or corroded connectors
5. PCM/TCM software or hardware fault
1. Hard or erratic shifting
2. Transmission stuck in one gear (limp mode)
3. Delayed gear engagement
4. Check Engine Light (CEL) ON
5. Poor fuel economy
1. Scan for DTCs using a professional scanner (check for related codes like P0760–P0765)
2. Inspect transmission fluid: Level, color (should be red/pink), and smell (shouldn’t be burnt)
3. Electrical check: Look for damaged wiring or corroded connectors going to the transmission
4. Test solenoid C: Using an ohmmeter or scan tool with actuator test
5. Valve body inspection (if accessible) — check for debris or sticking valves
1. Replace shift solenoid C
2. Flush and replace transmission fluid/filter
3. Repair or replace damaged wiring or connectors
4. Update or reprogram PCM/TCM software
5. Rebuild or replace transmission (in severe cases)
