P1747 Code? Here’s How to Fix It – Quickly and Easily

To quickly fix the P1747 code, start by checking the transmission fluid level, inspecting the wiring, and testing the solenoid.

This error code usually indicates an issue with the pressure control solenoid, which can affect how your vehicle shifts gears.

First, make sure the transmission fluid is clean and at the right level.

Next, look at the wiring for any damage or loose connections.

If the problem continues, use a multimeter to check the solenoid’s electrical parts.

If these steps don’t solve the issue, what should you do next?

Key Takeaways

• Look for and fix any damaged or corroded transmission wires.
• Check the transmission fluid and add more if it’s low or replace it if it’s dirty.
• Test the pressure control solenoid to see if it’s working right and replace it if it’s not.
• Use a scan tool to clear the P1747 code and see if the problem comes back.

What Is the P1747 Code?

The P1747 code means there’s an electrical problem with the pressure control solenoid (PCS) in the transmission. This solenoid helps control the fluid pressure in the transmission, which is crucial for smooth shifting and overall performance.

If the PCS isn’t working right, you might notice issues like rough shifting, slipping gears, or even a complete transmission failure. This code can show up in many different car makes and models, and when it does, the check engine light will come on.

Knowing what the P1747 code means can help you understand the role of the PCS and why it’s important to fix electrical problems quickly to keep your transmission working well.

Symptoms of the P1747 Code

You might notice several signs when dealing with a P1747 code, including rough shifting and gears slipping. These problems can really mess with your car’s transmission.

Here’s a quick list of what to look out for:

1. Rough Shifting: Your car may change gears suddenly, giving you a jolt.
2. Gears Slipping: The transmission might have trouble staying in gear, causing surprise shifts.
3. Check Engine Light: This light often comes on when the P1747 code is detected.

Causes of P1747 Code

A P1747 code usually means there’s a problem with the pressure control solenoids in your car’s transmission. These solenoids help manage how your transmission shifts gears. If they fail, you might notice your car shifting roughly or even the transmission failing completely.

Bad wiring in the transmission can also mess up the solenoids, so you’ll need to check the electrical connections. Low or dirty transmission fluid can clog the solenoids, causing them to malfunction and trigger the P1747 code. Other issues within the transmission might also be to blame.

To fix this, you should check the transmission fluid, look for any wiring damage, and make sure the solenoids and other parts are working as they should.

Vehicles Affected by P1747

Vehicles often experiencing the P1747 code include the Ford Taurus, Ford Explorer, and Lincoln LS, among other models with automatic transmissions. These cars are likely to have transmission problems because of issues with different types of solenoids. If you own one of these models, the P1747 code might signal an electrical problem with the pressure control solenoid (PCS).

Here are three key points to keep in mind:

1. Transmission Performance: A bad PCS can make shifting gears rough and harm the transmission.
2. Solenoid Types: Various solenoids in the transmission can fail and cause similar issues.
3. Affected Models: While Ford and Lincoln are common, other makes with automatic transmissions can also face this problem.

Knowing these points can help you deal with the P1747 code more effectively.

Diagnosing P1747 Code

To figure out the P1747 code, start by using a scan tool to get the specific code and any other related codes from the car’s computer.

Next, use diagnostic tools to check the transmission system carefully.

Begin with a visual check of the wiring to see if there’s any damage or loose connections that might affect the pressure control solenoid.

Use troubleshooting techniques to look at the transmission valve body for any debris or damage that could stop it from working properly.

Also, check the solenoid’s electrical parts to make sure they’re working right and have continuity.

These steps will help you find the root cause of the error, ensuring an accurate diagnosis and a focused repair strategy.

Checking Transmission Fluid

Checking Transmission Fluid

Before getting into more complicated problems, check the transmission fluid level and condition to rule out basic issues. Proper transmission maintenance starts with making sure the fluid is at the right level and in good shape.

Follow these steps:

1. Check Fluid Level: With the engine running and warmed up, pull out the dipstick, wipe it clean, put it back in, and then pull it out again to check the level.
2. Inspect Fluid Condition: Look at the fluid’s color and smell. Good fluid should be a clear red and shouldn’t smell burnt.
3. Top-Up or Replace Fluid: If the level is low or the fluid looks dirty, add more or change it to keep your transmission working well.

Regular checks are important to prevent issues like the P1747 code.

Inspecting Transmission Wiring

When figuring out the P1747 code, take a good look at the transmission wiring to make sure there are no damaged, corroded, or loose connections affecting the pressure control solenoid.

Start by visually checking all connectors and wires for any signs of wear or rust.

Use a multimeter to test for continuity and the right voltage levels in the wiring harness.

Pay extra attention to any bare sections that might be easily damaged by the environment.

Make sure all connections are tight and clean.

Bad wiring can mess up the pressure control solenoid, causing the transmission to act up.

Fix any wiring problems you find right away to keep the transmission running smoothly.

Solenoid Replacement

After making sure the transmission wiring is in good shape and working right, the next step is to replace the broken pressure control solenoid to fix the P1747 code.

First, test the solenoid to make sure it’s really the problem. Use a multimeter to measure the solenoid’s resistance and compare it to what the manufacturer says it should be. If it’s bad, follow these steps to replace it:

1. Take out the old solenoid: Unplug the transmission harness and remove the bolts holding the broken solenoid.
2. Put in the new solenoid: Position it correctly and bolt it in place, making sure it’s secure.
3. Reconnect the wiring: Plug the transmission harness back in and check all the connections.

Fluid Maintenance Tips

Taking care of your transmission fluid is crucial to avoid problems like the P1747 code and to keep your vehicle’s transmission running smoothly for a long time.

Start by regularly checking the fluid level and its condition. If the fluid is low, the transmission can overheat or get dirty, which can mess up the solenoids.

Always use the transmission fluid recommended by your vehicle’s manufacturer and change it as advised in the owner’s manual.

Make sure the transmission system is sealed properly to prevent dirt from getting in.

Keep an eye on the fluid for any discoloration or burnt smell, which are signs of contamination.

When to Seek Help

If you’ve taken good care of your transmission fluid but still run into problems like the P1747 code, it’s time to get professional help. Experts can accurately find and fix the root issues, preventing more damage down the road.

Here’s when you should consider seeing a pro:

1. Ongoing Problems: If the P1747 code keeps coming back even after you’ve tried changing the fluid and other simple fixes.
2. Complicated Issues: When the problem involves complex electrical or mechanical parts that require more than basic tools and know-how.
3. Warranty Issues: To make sure you don’t void any existing vehicle warranties, it’s best to let a professional handle it.
