Revolutionize Your Drive: Learn How to Change Transmission Fluid Subaru Crosstrek in Minutes!

Keeping your Subaru Crosstrek running smoothly requires regular maintenance, and changing the transmission fluid is a crucial part of that. While it might seem daunting, changing the transmission fluid in your Subaru Crosstrek is a task that many DIY enthusiasts can handle. This guide will walk you through the process step-by-step, ensuring you have all the information you need to successfully complete this important maintenance task.

Why Change Transmission Fluid?

Transmission fluid, also known as ATF (Automatic Transmission Fluid), is essential for lubricating the gears and components within your Subaru Crosstrek‘s transmission. Over time, this fluid breaks down, loses its lubricating properties, and can even become contaminated with metal shavings and other debris. This can lead to a variety of problems, including:

• Rough shifting: A common symptom of worn-out transmission fluid is difficulty shifting gears smoothly, leading to a jerky or hesitant transmission.
• Transmission overheating: As the fluid breaks down, it loses its ability to transfer heat effectively, potentially leading to overheating and damage.
• Transmission failure: In extreme cases, failure to change the transmission fluid can result in complete transmission failure, a costly repair.

Tools and Materials You’ll Need

Before you begin, gather the following tools and materials:

• New transmission fluid: Refer to your Subaru Crosstrek’s owner’s manual for the correct type and quantity of fluid. Subaru recommends using genuine Subaru ATF.
• Transmission fluid drain pan: A large pan to catch the old fluid.
• Torque wrench: To ensure proper tightening of bolts and drain plugs.
• Jack and jack stands: To safely lift the vehicle.
• Wrench set: To loosen and tighten various bolts and nuts.
• Funnel: To pour the new transmission fluid.
• Clean rags: For wiping up spills and cleaning tools.
• Gloves: To protect your hands from the hot fluid.
• Safety glasses: To protect your eyes from splashes.

Step-by-Step Guide to Changing Transmission Fluid

1. Preparation and Safety:

• Park on a level surface: Make sure the vehicle is parked on a level surface and engage the parking brake.
• Warm up the transmission: Drive the Crosstrek for a few minutes to warm up the transmission fluid, making it more fluid and easier to drain.
• Safety first: Wear safety glasses and gloves to protect yourself from hot fluid and potential spills.

2. Access the Transmission Drain Plug:

• Locate the drain plug: The transmission drain plug is typically located on the bottom of the transmission pan, near the front of the vehicle. Consult your owner’s manual for the exact location.
• Position the drain pan: Place the drain pan directly beneath the drain plug.

3. Drain the Old Transmission Fluid:

• Loosen the drain plug: Carefully loosen the drain plug using a wrench. Be cautious as the fluid will be hot.
• Allow the fluid to drain: Let the old fluid drain completely into the pan. It may take some time, so be patient.

4. Replace the Drain Plug:

• Clean the drain plug: Wipe the drain plug clean with a rag to remove any debris.
• Tighten the drain plug: Replace the drain plug and tighten it to the correct torque specification found in your owner’s manual. Overtightening can damage the plug.

5. Access the Transmission Fill Plug:

• Locate the fill plug: The transmission fill plug is usually located on the side of the transmission pan, near the top.
• Clean the fill plug: Wipe the fill plug clean with a rag.

6. Fill with New Transmission Fluid:

• Use a funnel: Use a funnel to pour the new transmission fluid into the fill plug opening.
• Check the fluid level: As you fill the transmission, check the fluid level by periodically removing the fill plug. The fluid should be level with the bottom of the fill hole.
• Tighten the fill plug: Once the fluid level is correct, replace the fill plug and tighten it to the proper torque specification.

7. Start the Engine and Check Fluid Level:

• Start the engine: Start the engine and let it idle for a few minutes.
• Check the fluid level again: With the engine running, check the fluid level again. If the level is low, add more fluid as needed.

8. Final Check and Clean Up:

• Check for leaks: Inspect the transmission for any leaks, especially around the drain and fill plugs.
• Clean up: Dispose of the old transmission fluid properly and clean up any spills.

Tips for Success

• Warm up the fluid: Always warm up the transmission fluid before draining to make it easier to drain and to ensure that you get most of the old fluid out.
• Use the correct fluid: Always use the correct type and quantity of transmission fluid recommended by Subaru for your Crosstrek.
• Torque the plugs properly: Use a torque wrench to ensure that both the drain plug and fill plug are tightened to the correct specification.
• Check for leaks: After completing the fluid change, check for any leaks around the drain and fill plugs.

Beyond the Basics: Additional Considerations

• Transmission Pan Replacement: Consider replacing the transmission pan if it shows signs of wear or damage, especially if you’re experiencing transmission problems. A new pan can help prevent future leaks and provide a fresh surface for the new fluid.
• Filter Replacement: Some Subaru Crosstrek models have a separate transmission filter. If yours does, it’s a good idea to replace the filter at the same time as the fluid change.
• Professional Service: If you’re not comfortable doing the transmission fluid change yourself, it’s best to take your Subaru Crosstrek to a qualified mechanic.

Answers to Your Most Common Questions

Q: How often should I change the transmission fluid in my Subaru Crosstrek?

A: Subaru recommends changing the transmission fluid every 30,000 miles or 3 years, whichever comes first. However, if you frequently drive in harsh conditions (extreme heat, heavy towing, or frequent stop-and-go traffic), you may need to change it more often.

Q: Can I use any type of transmission fluid in my Subaru Crosstrek?

A: No, it’s essential to use the correct type of transmission fluid recommended by Subaru for your Crosstrek. Using the wrong type of fluid can damage your transmission.

Q: What are the signs that my transmission fluid needs to be changed?

A: Some signs that your transmission fluid needs to be changed include rough shifting, slipping gears, a burning smell, and a low fluid level.

Q: What happens if I don’t change my transmission fluid?

A: If you don’t change your transmission fluid, it can break down, lose its lubricating properties, and become contaminated. This can lead to a variety of problems, including rough shifting, transmission overheating, and even transmission failure.

Q: Can I change the transmission fluid myself?

A: Yes, you can change the transmission fluid yourself. However, it’s important to follow the instructions carefully and use the correct tools and materials. If you’re not comfortable doing it yourself, it’s best to take your Subaru Crosstrek to a qualified mechanic.
