P0769

2017-10-10

Description:

  • The fault code P0769 indicates an intermittent issue with the shift solenoid 'D'. This fault code typically points to an irregular operation or malfunction of the shift solenoid 'D' or its control circuit, which is responsible for controlling the hydraulic pressure to engage the corresponding gear in the transmission.

Possible Symptoms:

  • Malfunction Indicator Lamp (MIL) or Check Engine Light illuminated

  • Erratic or inconsistent shifting between gears

  • Harsh or delayed shifting

  • Failure to shift into the corresponding gear

  • Decreased fuel efficiency

  • Potential limited vehicle performance or drivability issues

Possible Causes:

  • Intermittent malfunction of the shift solenoid 'D'

  • Wiring or connection problems in the shift solenoid 'D' circuit

  • Loose or corroded connectors in the transmission system

  • Low transmission fluid level or contaminated fluid

  • Faulty transmission control module (TCM)

  • Internal transmission damage or mechanical failure

Related Parts:

  • Transmission Shift Sensor: Gear Shift Sensor communicates the position the gear shifted to. Problems lead to difficulty in shifting gears

Possible Solutions:

  • Inspect and test the shift solenoid 'D' for proper functionality, and replace it if necessary

  • Check the wiring and connections in the shift solenoid 'D' circuit for any damage, loose connections, or corrosion, and repair as needed

  • Ensure the transmission fluid level is correct and free from contamination, and perform a fluid flush if needed

  • Inspect and clean or repair any loose or corroded connectors in the transmission system

  • Test the transmission control module (TCM) for proper functionality and replace it if necessary

  • Perform a thorough diagnostic of the transmission to identify any internal damage or mechanical issues
