P0769: Shift solenoid D circuit intermittent
Shift solenoid D intermittent circuit
Severity: Severity not verified — if the car runs badly, have it inspected
The two sources give the code definition but no severity rating, so the urgency is not verified. A shift fault can leave the car in a fixed gear, so have it checked soon.
P0769 in short
P0769 means the computer saw an intermittent fault in the circuit of shift solenoid D, which comes and goes. TroubleCodes.net lists wiring, a poor connection, the solenoid or the control module as the probable causes. A scan tool that reads the transmission module is needed to confirm which.
Shift solenoid D is a valve that helps the transmission change gears. An intermittent fault means the circuit dropped out briefly rather than failing outright.
TroubleCodes.net lists wiring, poor connection, the shift solenoid and the engine or transmission control module as probable causes, and notes basic code readers cannot reach the transmission module to tell which.
Most likely causes
These are general causes for this code across vehicles. None is specific to one make or model.
Cause 1: Wiring, grounds or connector fault in the solenoid circuit
Common general cause- Why it ranks here
- TroubleCodes.net lists wiring, poor connections and bad grounds as probable causes of the solenoid circuit codes.
- What would change this
- Rises if a wire is chafed or a connector is corroded. Falls if the circuit tests normal.
Cause 2: Faulty shift solenoid
Common general cause- Why it ranks here
- TroubleCodes.net lists the shift solenoid itself as a probable cause once the wiring tests sound.
- What would change this
- Rises if the solenoid fails a resistance or command test. Falls if it responds correctly.
Cause 3: Low, dirty or wrong transmission fluid
Common general cause- Why it ranks here
- TroubleCodes.net lists low or dirty fluid among the first causes for a shift fault and it is the cheapest thing to check.
- What would change this
- Rises if the level is low or the fluid is dark or burnt. Falls if level and condition are correct.
Cause 4: Transmission or engine control module fault
Possible — needs testing- Why it ranks here
- TroubleCodes.net lists the control module as a cause but after the wiring and solenoid, so it ranks last.
- What would change this
- Rises if wiring and solenoid test good and the fault stays. Falls if either is faulty.
What to test first
Start at step 1. Each result tells you what it means and where to go next.
Step 1: Read every stored code and freeze-frame data with a scan tool that can read the transmission module.
IfOther transmission codes are stored
It meansWork from the first code stored; one fault can set several.
IfIt is the only code
It meansCheck the fluid and wiring next.
Step 2: Have the transmission fluid level and condition checked following the maker's procedure.
Warning:Many transmissions are checked hot with the engine running, and some are sealed with no dipstick. Let a shop do this.
IfFluid is low, dark, burnt or the wrong type
It meansFluid is the first suspect.
IfFluid is fine
It meansHave the circuit tested.
Step 3: Have the wiring and connectors flexed and tested while a scan tool watches the solenoid circuit, to catch the drop-out.
Warning:Testing solenoid circuits means working at the transmission connector and sometimes dropping the pan, with hot fluid and a moving drivetrain risk. Let a shop do this.
IfA damaged wire or corroded connector is found
It meansRepair it.
Points to: Wiring, grounds or connector fault in the solenoid circuit
IfThe circuit is sound
It meansThe part itself is next.
Points to: Wiring, grounds or connector fault in the solenoid circuit
Symptoms
- Check engine light
- Occasional harsh or erratic shifts
How to fix
Step 1: Have a shop scan the transmission module for every stored code before any parts are replaced.
Step 2: Ask a dealer whether a transmission software update or bulletin applies to your VIN.

P0769 questions
Why does P0769 come and go?
Intermittent means the circuit fault is not always present, which points first to a loose connector or chafed wiring.
