Shift Solenoid D Stuck On

Completed
100%
Causes
- Short in solenoid D circuit to power (constant 12V)
- Shift solenoid D coil internally shorted or welded
- Stuck/blocked valve in the valve body preventing bleed/drain
- Faulty transmission control module (TCM) or driver transistor
- Poor electrical connections, corroded connector or damaged pin
- Low, dirty, or contaminated transmission fluid causing solenoid/valve sticking
Symptoms
- Check Engine / Transmission warning light illuminated
- Transmission stuck in a gear or limp/limitation mode
- Harsh, delayed, or erratic shifts
- Transmission won’t shift into certain gears or stalls during shifts
- Reduced fuel economy
- Possible unusual transmission noises
What to check
- Retrieve freeze frame and full DTC list; note conditions when code set
- Visually inspect transmission fluid level and condition (color, smell, debris)
- Inspect wiring harness and connector for solenoid D for damaged insulation, corrosion, or pins pushed out
- Check for TSBs or known issues for the vehicle model (if available)
- Backprobe the solenoid connector while operating (see signal parameters)
- Measure solenoid coil resistance with connector disconnected
Signal parameters
- Solenoid coil resistance (typical factory range): approx. 10–40 ohms (varies by vehicle). Refer to vehicle spec before replacement.
- When commanded ON: controller drives the solenoid with a switched/pulsed voltage (PWM) or applies ground — expect pulsed voltage between 0–12 V at PWM frequency (commonly 70–250 Hz).
- When commanded OFF: no PWM pulses; connector should not see continuous battery voltage or continuous ground — reading should be high/none depending on driver type.
- Short to battery: steady ~12 V at solenoid connector when solenoid is commanded OFF.
- Short to ground: near 0 V at connector regardless of command.
Diagnostic algorithm
- Read and record all DTCs and freeze-frame data. Note operating conditions (temp, RPM, gear, vehicle speed).
- Inspect transmission fluid level/condition. If fluid is severely degraded or contaminated, consider fluid and filter service before further electrical tests.
- Visually inspect solenoid D connector and wiring for damage, corrosion, chafing, or pin push-out. Repair any obvious wiring/connectors.
- With ignition OFF, disconnect the solenoid connector. Measure coil resistance across solenoid terminals. Compare to vehicle spec. A near-infinite or very high reading = open coil; near-zero indicates short.
- With connector disconnected, check for unexpected battery voltage or ground on the harness side (backprobe). If 12V is present when solenoid is OFF, likely short to power in wiring.
- Reconnect and backprobe while commanding solenoid ON/OFF with a scan tool. Observe voltage/pulse behavior and compare to expected PWM. Use an oscilloscope if available for waveform analysis.
- Wiggle test wiring while monitoring signal to find intermittent faults. Check grounds and related fuses/circuit breakers.
- If wiring and connector OK but solenoid behavior is incorrect, remove and bench-test or replace solenoid D. If swapping with another identical solenoid clears the code, replace the faulty solenoid.
- If solenoid and wiring check good, suspect TCM driver fault. Confirm by checking other solenoid circuits and related outputs; consult manufacturer procedures for TCM testing and replacement.
- After repair, clear codes and perform road test under the same conditions to verify the code does not return.
Likely causes
- Shorted wiring or connector to transmission battery feed (most common)
- Failed/shorted shift solenoid D
- Contaminated transmission fluid or debris causing valve to stick
- Poor ground or corroded connector at solenoid
- TCM driver failure (less common)
Fault status
Status
P0767 - Shift Solenoid D Circuit Stuck On: TCM detects solenoid D remains energized or circuit is shorted ON.
Repair difficulty: Medium
Diagnostic time: 1-3 hours
