P0776 – OBD-II DTC

OBD-II DTC P0776 – Shift Solenoid E Stuck On

DTC P0776 meaning

DTC P0776 refers to a diagnostic trouble code indicating that the Shift Solenoid E is stuck in the “on” position. This code is specific to the transmission system and is part of the On-Board Diagnostics II (OBD-II) system. The shift solenoid is responsible for controlling the flow of transmission fluid, which in turn affects the shifting of gears. When the solenoid is stuck, it can lead to improper shifting and affect the overall performance of the vehicle.

DTC P0776 symptoms

Common symptoms associated with DTC P0776 may include:

• Delayed or harsh shifting between gears
• Transmission slipping or failing to engage
• Increased engine RPM without corresponding acceleration
• Check Engine Light illuminated on the dashboard
• Unusual noises from the transmission

DTC P0776 causes

Several factors can lead to the occurrence of DTC P0776, including:

• Faulty shift solenoid E
• Wiring issues or poor electrical connections
• Low transmission fluid levels or fluid contamination
• Faulty transmission control module (TCM)
• Mechanical issues within the transmission

DTC P0776 seriousness

DTC P0776 is considered a serious issue as it can lead to significant transmission problems. If left unaddressed, it may result in complete transmission failure, which can be costly to repair. Additionally, the symptoms associated with this code can affect the drivability and safety of the vehicle, making it essential to diagnose and resolve the issue promptly.

How to diagnose DTC P0776

To diagnose DTC P0776, follow these steps:

1. Use an OBD-II scanner to confirm the presence of the P0776 code.
2. Check for any additional trouble codes that may provide more context.
3. Inspect the transmission fluid level and condition.
4. Examine the wiring and connectors related to the shift solenoid E for damage or corrosion.
5. Test the shift solenoid E for proper operation using a multimeter.
6. Check the transmission control module (TCM) for faults.
7. Perform a road test to observe the transmission behavior.

How to fix DTC P0776 step-by-step instructions

To fix DTC P0776, follow these steps:

1. Address any low or contaminated transmission fluid by replacing it and ensuring the correct level.
2. Repair or replace any damaged wiring or connectors related to the shift solenoid E.
3. If the shift solenoid E is faulty, replace it with a new one.
4. Check and, if necessary, replace the transmission control module (TCM).
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 P0776

To erase DTC P0776, 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 scanner’s menu and select the option to clear or erase trouble codes.
4. Confirm the action and wait for the scanner to complete the process.
5. Disconnect the scanner and start the vehicle to check if the code reappears.
