How to Fix P0774 Shift Solenoid E Malfunction
If you’re experiencing issues with your car’s transmission, specifically the P0774 Shift Solenoid E Malfunction code, you’re not alone. This code is a common problem that many car owners face, but fortunately, it’s not a difficult issue to fix. In this article, we’ll provide you with a step-by-step guide on how to fix the P0774 Shift Solenoid E Malfunction code.
What is the P0774 Shift Solenoid E Malfunction Code?
The P0774 Shift Solenoid E Malfunction code is a diagnostic trouble code (DTC) that indicates a problem with the shift solenoid E circuit. The shift solenoid E is responsible for controlling the flow of transmission fluid to the clutch pack that engages the gears. When this solenoid fails, it can cause a variety of transmission problems, including harsh shifting, slipping, and even complete transmission failure.
Step-by-Step Guide to Fixing the P0774 Shift Solenoid E Malfunction Code
Step 1: Check the Transmission Fluid Level
The first step in fixing the P0774 Shift Solenoid E Malfunction code is to check the transmission fluid level. Low transmission fluid levels can cause a variety of transmission problems, including the P0774 code. To check the transmission fluid level, follow these steps:
1. Park your car on a level surface and turn off the engine.
2. Locate the transmission dipstick (usually near the back of the engine).
3. Pull out the dipstick and wipe it clean with a rag.
4. Reinsert the dipstick and pull it out again.
5. Check the fluid level on the dipstick. The fluid should be between the “full” and “add” marks.
If the transmission fluid level is low, add more fluid until it reaches the “full” mark. Be sure to use the correct type of transmission fluid for your car.
Step 2: Check the Shift Solenoid E Circuit
If the transmission fluid level is not the problem, the next step is to check the shift solenoid E circuit. To do this, you’ll need a multimeter. Follow these steps:
1. Disconnect the battery to prevent any electrical damage.
2. Locate the shift solenoid E on your car’s transmission.
3. Disconnect the wiring harness from the shift solenoid E.
4. Set your multimeter to measure resistance (ohms).
5. Touch the multimeter leads to the two terminals on the shift solenoid E.
6. The multimeter should read between 20 and 30 ohms. If it reads outside of this range, the shift solenoid E is faulty and needs to be replaced.
Step 3: Replace the Shift Solenoid E
If the shift solenoid E is faulty, the next step is to replace it. Follow these steps:
1. Purchase a new shift solenoid E from your local auto parts store.
2. Disconnect the battery to prevent any electrical damage.
3. Locate the shift solenoid E on your car’s transmission.
4. Remove the bolts that hold the shift solenoid E in place.
5. Pull the shift solenoid E out of the transmission.
6. Install the new shift solenoid E and tighten the bolts.
7. Reconnect the wiring harness to the shift solenoid E.
8. Reconnect the battery.
Fixing the P0774 Shift Solenoid E Malfunction code is a relatively simple process that can be done at home with a few basic tools. By following the steps outlined in this article, you can save yourself time and money by avoiding a trip to the mechanic.
1. Can I still drive my car with the P0774 Shift Solenoid E Malfunction code?
It’s not recommended to drive your car with the P0774 code as it can cause further damage to your transmission. It’s best to fix the issue as soon as possible.
2. How much does it cost to fix the P0774 Shift Solenoid E Malfunction code?
The cost of fixing the P0774 code can vary depending on the make and model of your car and the severity of the issue. On average, it can cost anywhere from $200 to $500 to fix.
3. How can I prevent the P0774 Shift Solenoid E Malfunction code from happening again?
Regular maintenance of your car’s transmission, including changing the transmission fluid and filter, can help prevent the P0774 code from happening again. It’s also important to address any transmission issues as soon as they arise to prevent further damage.
