As a Subaru owner, you know how important all the components in your car’s transmission system are. One of the most essential components in your transmission system is the shifter switch solenoid. The solenoid is responsible for transferring the current and allowing you to shift gears with ease. A faulty shifter switch solenoid can cause your car to not start or even make it impossible to shift into the correct gear.
If you’re experiencing issues with your shifter switch solenoid, replacing it might be the next step. In this guide, we will show you how to replace the shifter switch solenoid in your Subaru with just a few tools and some basic mechanical knowledge.
What is a Shifter Switch Solenoid and How Does it Work?
Before we dive into the process of replacing the shifter switch solenoid, let’s first understand what it does and how it works. The shifter switch solenoid is an electromagnetic device that transfers current in your car’s transmission system. When you shift gears in your car, the shifter switch solenoid sends an electrical signal to the transmission control module to ensure that the car is in the right gear. If the shifter switch solenoid is faulty, you will experience difficulty shifting gears or won’t be able to shift at all.
Signs of a Faulty Shifter Switch Solenoid
When the shifter switch solenoid begins to fail, there are a few signs that you can look out for including:
- Difficulty shifting gears
- Inability to shift gears into or out of park
- The gear shift feeling "stuck" in one gear
- The shifter switch solenoid clicking or buzzing when trying to shift
If you’re experiencing any of these issues, it’s time to replace the shifter switch solenoid in your Subaru.
Tools and Equipment Needed
Replacing the shifter switch solenoid in your Subaru is a relatively straightforward task that requires a few basic tools and equipment, including:
- Socket set
- Wrench set
- Replacement shifter switch solenoid
- Safety glasses
- Work gloves
Step-by-Step Guide to Replace Shifter Switch Solenoid
Now that you have the correct tools and equipment, it’s time to replace your shifter switch solenoid. Here’s how to do it in easy eight steps:
Step 1: Disconnect the Battery
Before working on any electrical component, it’s essential to disconnect the battery. This will help prevent the risk of electrical shock.
Step 2: Locate the Shifter Switch Solenoid
Find the shifter switch solenoid on your Subaru. It’s usually located on the transmission assembly, near the shift linkage.
Step 3: Remove the Old Solenoid
Use your socket set and wrench set to remove the old shifter switch solenoid. Take note of how the old solenoid is installed so that you can install the new one correctly.
Step 4: Disconnect the Wires
Disconnect the wires that are attached to the old shifter switch solenoid. You can use pliers to gently pull them out.
Step 5: Install the New Shifter Switch Solenoid
Insert the new shifter switch solenoid into the same place as the old one and connect the wires to the new solenoid.
Step 6: Tighten the New Solenoid
Use your wrench set and socket set to tighten the new shifter switch solenoid in place.
Step 7: Test Your Shifter Switch
Reconnect the battery and test the shifter switch. Shift gears into neutral and reverse to make sure that the new shifter switch solenoid is working correctly.
Step 8: Reassemble and Clean
Once you have confirmed that the new solenoid is working efficiently, reassemble any parts that you removed and clean up your workspace.
Tips and Precautions to Ensure a Successful Replacement
Here are a few tips and precautions to keep in mind to ensure that the replacement process goes smoothly:
- Always disconnect the battery before working on any electrical component.
- Don’t touch any of the electrical components with wet hands or a wet cloth.
- Always wear safety glasses and work gloves.
- Handle the wiring gently to avoid damaging any of the components.
- Take your time and follow the instructions carefully to avoid any mistakes.
Troubleshooting Common Issues During the Replacement
If your shifter switch solenoid replacement isn’t going as planned, here are a few common issues that you may encounter:
- Trouble disconnecting the wires: If you’re having trouble disconnecting the wires, you can use a pair of pliers to give you a better grip.
- Difficulty removing the old solenoid: A rusted or seized-up shifter switch solenoid can be challenging to remove. You can use a lubricant like WD-40 to help loosen the solenoid and make it easier to remove.
- Engine warning light: If your engine warning light comes on after you install the new shifter switch solenoid, it could mean that there’s another electrical issue. You will need to take your car to a mechanic to diagnose the issue.
Replacing a shifter switch solenoid in your Subaru is a straightforward task that can be completed with basic tools and some automotive mechanical knowledge. By following these steps, you can ensure that your car’s transmission system is functioning correctly and avoid any potential problems that can arise from a faulty shifter switch solenoid.
