How to Fix P0775 Shift Solenoid E Performance or Stuck Off

Introduction

If you’re experiencing issues with your car’s transmission, specifically the P0775 error code, you may be wondering what steps you can take to fix the problem. The P0775 error code indicates that there is an issue with the shift solenoid E performance or that it is stuck off. This can cause your car to have trouble shifting gears, which can be frustrating and potentially dangerous. In this article, we’ll provide you with step-by-step instructions on how to fix the P0775 error code.

Step 1: Check the Transmission Fluid

The first step in fixing the P0775 error code is to check the transmission fluid. Low transmission fluid levels can cause a variety of transmission issues, including trouble shifting gears. To check the transmission fluid, locate the transmission dipstick under the hood of your car. Pull the dipstick out and wipe it clean with a rag. Then, reinsert the dipstick and pull it out again. Check the level of the fluid on the dipstick. If the fluid level is low, add more transmission fluid until it reaches the appropriate level.

Step 2: Replace the Shift Solenoid E

If the transmission fluid level is not the issue, the next step is to replace the shift solenoid E. The shift solenoid E is responsible for controlling the flow of transmission fluid to the clutch packs that control the shifting of gears. If the solenoid is not functioning properly, it can cause the P0775 error code. To replace the shift solenoid E, follow these steps:

1. Locate the shift solenoid E. It is typically located on the side of the transmission.

2. Disconnect the electrical connector from the solenoid.

3. Remove the bolts that hold the solenoid in place.

4. Remove the old solenoid and replace it with a new one.

5. Reattach the bolts and electrical connector.

Step 3: Check the Wiring

If replacing the shift solenoid E does not fix the issue, the next step is to check the wiring. The wiring that connects the solenoid to the transmission control module can become damaged or corroded over time, which can cause the P0775 error code. To check the wiring, follow these steps:

1. Locate the wiring that connects the shift solenoid E to the transmission control module.

2. Inspect the wiring for any signs of damage or corrosion.

3. If the wiring is damaged or corroded, replace it with a new wiring harness.

Step 4: Replace the Transmission Control Module

If none of the previous steps have fixed the issue, the final step is to replace the transmission control module. The transmission control module is responsible for controlling the shifting of gears in your car’s transmission. If it is not functioning properly, it can cause a variety of transmission issues, including the P0775 error code. To replace the transmission control module, follow these steps:

1. Locate the transmission control module. It is typically located under the hood of your car.

2. Disconnect the electrical connector from the module.

3. Remove the bolts that hold the module in place.

4. Remove the old module and replace it with a new one.

5. Reattach the bolts and electrical connector.

Conclusion

Fixing the P0775 error code can be a frustrating and time-consuming process, but by following these steps, you can get your car back on the road and running smoothly. Remember to always check the transmission fluid level first, as low fluid levels can cause a variety of transmission issues. If that doesn’t fix the issue, move on to replacing the shift solenoid E, checking the wiring, and replacing the transmission control module if necessary.

FAQs

1. Can I drive my car with the P0775 error code?

It is not recommended to drive your car with the P0775 error code. This error code indicates that there is an issue with the shift solenoid E performance or that it is stuck off, which can cause your car to have trouble shifting gears. This can be dangerous and potentially cause further damage to your car’s transmission.

2. How much does it cost to fix the P0775 error code?

The cost to fix the P0775 error code can vary depending on the cause of the issue. If it is a simple fix, such as adding more transmission fluid, the cost may be minimal. However, if the issue requires replacing the shift solenoid E or the transmission control module, the cost can be more significant.

3. Can I fix the P0775 error code myself?

If you have experience working on cars and feel comfortable working with transmissions, you may be able to fix the P0775 error code yourself. However, if you are not experienced with car repairs, it is recommended to take your car to a professional mechanic to avoid causing further damage to your car’s transmission.
