P0769 — Shift Solenoid D Intermittent

Generic OBD-II · all makesPowertrain (engine & transmission)

The code signals that the transmission's shift solenoid D is not operating as expected, often due to electrical or mechanical faults. It may affect gear shifting performance and trigger the malfunction indicator lamp.

Symptoms

What causes it — most likely first

1. Shift solenoid D failure

The solenoid can wear out or become internally shorted, causing intermittent operation.

2. Wiring or connector issue

Corroded, damaged, or loose connections to the solenoid can interrupt signal flow.

3. Low or contaminated transmission fluid

Insufficient or degraded fluid can affect solenoid actuation and hydraulic pressure.

4. Faulty transmission control module

A problem within the module that controls solenoids can cause intermittent faults, though this is less common.

5. PCM failure

Complete failure of the powertrain control module is rare and typically only after other components have been ruled out.

How it's diagnosed

  1. Connect an OBD-II scanner and record all stored and pending codes.
  2. Check transmission fluid level and condition, topping up or replacing if necessary.
  3. Inspect wiring harness and connectors for the shift solenoid D for corrosion, damage, or loose pins.
  4. Measure resistance and voltage at the solenoid while the transmission is commanded to shift.
  5. Replace the shift solenoid D if it fails the electrical tests.
  6. Clear codes and perform a road test to verify the repair.

Frequently asked

What does P0769 indicate?

It indicates an intermittent fault with shift solenoid D, which controls a specific gear change in the transmission.

Can low transmission fluid cause this code?

Yes, low or degraded fluid can impair solenoid operation and trigger the code.

Do I need to replace the PCM?

Replacing the PCM is rarely necessary; the issue is usually a faulty solenoid, wiring, or fluid condition.

How long does a shift solenoid replacement take?

Typically a few hours, depending on vehicle design and whether additional components need removal.
