P0761 Shift Solenoid C Performance or Stuck Off

P0761 indicates shift solenoid C performance or stuck-off behavior. The controller commanded the solenoid but did not see the expected gear or pressure change.

Code details

Generic OBD-II · P0

System: Transmission
Code type: Generic (SAE / ISO controlled)
Standard: SAE J2012 / ISO 15031-6

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not assume the solenoid coil is electrically open; performance faults can be hydraulic, mechanical, or fluid related.

Symptoms of P0761

Harsh, delayed, or slipping shifts, or being stuck in one gear.
Check-engine light, sometimes with limp-home mode.
Flaring RPM or a shudder under load.

Common causes of P0761

Low or degraded transmission fluid.
A failing speed sensor, shift solenoid, or pressure-control circuit.
Wiring, connector, or internal hydraulic/mechanical faults.

Useful checks before replacing parts

Compare solenoid C command with actual ratio, shift timing, turbine speed, output speed, and pressure-control data.
Inspect fluid contamination, valve-body sticking, solenoid response, wiring, and connector condition.
Review temperature and load conditions because performance faults may appear only hot or during one shift.
