What Does P0761 Mean?
Shift Solenoid C is performing outside its expected range or is mechanically stuck in the off position. The TCM commands solenoid C to activate but the expected gear ratio change does not occur. This typically affects 3rd or 4th gear engagement depending on the transmission design, resulting in missed shifts or gear slippage.
Common Causes
35%
Shift solenoid C stuck closed due to debris, varnish, or mechanical failure
25%
Valve body wear in the solenoid C shift valve bore
20%
Contaminated transmission fluid clogging solenoid passages
15%
Internal clutch pack failure in the gear circuit controlled by solenoid C
5%
Wiring resistance issue preventing full solenoid actuation
Diagnostic Steps
1
Monitor commanded vs. actual gear ratio in live data to confirm solenoid C is being commanded but not producing the expected shift.
2
Check transmission fluid level and quality — low or contaminated fluid directly impacts solenoid performance.
3
Measure solenoid C resistance at the transmission connector and verify it is within manufacturer specification.
4
Command solenoid C on/off with a bi-directional scan tool and listen for the audible click at the transmission.
5
Drop the transmission pan and inspect for excessive clutch material debris, which would indicate internal damage beyond the solenoid.

The most common cause of P0761 (Shift Solenoid C Performance or Stuck Off) is: Shift solenoid C stuck closed due to debris, varnish, or mechanical failure
Typical repair costs for P0761 range from $200 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The transmission may skip a gear or remain in a lower gear. Driving is possible at reduced speed but avoid sustained highway driving. Have the issue diagnosed soon to prevent secondary transmission damage.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0761 to identify the root cause.
