P0768 – OBD-II DTC

OBD-II DTC P0768 – Shift Solenoid C Intermittent

DTC P0768 meaning

DTC P0768 refers to a problem with the shift solenoid C in the vehicle’s transmission system. The shift solenoid is responsible for controlling the flow of transmission fluid, which is essential for shifting gears. When the powertrain control module (PCM) detects an intermittent issue with this solenoid, it triggers the P0768 code. This can lead to improper shifting, affecting the vehicle’s performance and drivability.

DTC P0768 symptoms

Common symptoms associated with DTC P0768 may include:

• Delayed or harsh shifting between gears
• Inability to shift into certain gears
• Transmission slipping
• Check Engine Light illuminated
• Unusual noises from the transmission

DTC P0768 causes

Several factors can contribute to the occurrence of DTC P0768, including:

• Faulty shift solenoid C
• Wiring issues, such as damaged or corroded connectors
• Low transmission fluid levels or dirty fluid
• Faulty PCM or transmission control module (TCM)
• Internal transmission problems

DTC P0768 seriousness

DTC P0768 can be considered serious as it directly impacts the vehicle’s transmission performance. If left unaddressed, it may lead to further transmission damage, reduced fuel efficiency, and potential safety hazards due to unpredictable shifting behavior. It is advisable to diagnose and repair the issue promptly to avoid more extensive repairs.

How to diagnose DTC P0768

To diagnose DTC P0768, follow these steps:

1. Use an OBD-II scanner to confirm the presence of the P0768 code.
2. Inspect the transmission fluid level and condition.
3. Check the wiring and connectors related to shift solenoid C for damage or corrosion.
4. Test the shift solenoid C for proper operation using a multimeter.
5. Examine the PCM and TCM for any faults or updates.
6. Perform a road test to observe the transmission behavior.

How to fix DTC P0768 step-by-step instructions

To fix DTC P0768, follow these steps:

1. Check and top off the transmission fluid if low.
2. Replace the transmission fluid if it is dirty or contaminated.
3. Inspect and repair any damaged wiring or connectors related to the shift solenoid C.
4. Replace the faulty shift solenoid C if testing indicates it is not functioning properly.
5. Clear the DTC using an OBD-II scanner.
6. Perform a road test to ensure the issue is resolved and the transmission operates smoothly.

How to erase DTC P0768

To erase DTC P0768, follow these steps:

1. Connect an OBD-II scanner to the vehicle’s diagnostic port.
2. Turn on the ignition without starting the engine.
3. Access the diagnostic menu on the scanner.
4. Select the option to clear or erase trouble codes.
5. Confirm the action and wait for the scanner to complete the process.
6. Disconnect the scanner and start the vehicle to check if the code reappears.
