Revolutionize Your Ride: How to Change BRZ Transmission Fluid for Peak Performance

The Subaru BRZ is a renowned sports car that delivers exhilarating performance and precise handling. To maintain its optimal driving experience, proper maintenance is crucial, and one of the essential tasks is changing the transmission fluid. This guide will walk you through the process of how to change BRZ transmission fluid, enabling you to keep your car running smoothly and maximizing its performance.

Why Change Your BRZ Transmission Fluid?

Transmission fluid acts as the lifeblood of your BRZ’s gearbox, lubricating the gears, reducing friction, and dissipating heat. Over time, this fluid degrades, losing its viscosity and ability to perform effectively. This can lead to:

• Rough shifting: The transmission may struggle to shift smoothly, resulting in clunky gear changes and a less enjoyable driving experience.
• Transmission damage: Insufficient lubrication can cause wear and tear on the gears and other internal components, leading to expensive repairs.
• Reduced performance: The transmission’s efficiency decreases, impacting acceleration and overall performance.

Gathering the Necessary Tools and Materials

Before diving into the process, ensure you have the following tools and materials:

• New transmission fluid: Refer to your BRZ’s owner’s manual for the recommended type and quantity of fluid.
• Drain pan: A large enough pan to collect the old fluid.
• Torque wrench: Essential for tightening bolts to the correct specifications.
• Jack and jack stands: To safely lift the car and provide a stable working platform.
• Wrench set: To loosen and tighten bolts.
• Funnel: For safely pouring new fluid into the transmission.
• Gloves: To protect your hands from oil and dirt.
• Clean rags: For wiping up spills and cleaning tools.
• Safety glasses: To protect your eyes from potential splashes.

Preparing the BRZ for Fluid Change

1. Park on a level surface: Ensure your BRZ is parked on a flat and stable surface.
2. Engage the parking brake: Set the parking brake firmly to prevent the car from rolling.
3. Warm up the engine: Run the engine for a few minutes to allow the transmission fluid to warm up and become more fluid.
4. Locate the drain plug: Underneath the car, find the drain plug on the transmission pan. It’s typically located near the bottom of the transmission, often with a 17mm or 19mm hex head.

Draining the Old Transmission Fluid

1. Place the drain pan: Position the drain pan directly beneath the drain plug.
2. Loosen the drain plug: Using a wrench, slowly loosen the drain plug. Be careful not to drop it into the drain pan.
3. Allow fluid to drain: Let the fluid drain completely into the drain pan. This may take a few minutes.
4. Remove the drain plug: Once the fluid stops draining, remove the drain plug and inspect it for any signs of wear or damage.
5. Clean the drain plug: Wipe off any debris or residue from the drain plug using a clean rag.
6. Replace the drain plug: Tighten the drain plug back into place using a torque wrench. Refer to your owner’s manual for the correct torque specification.

Refilling the Transmission with New Fluid

1. Locate the fill plug: On the transmission, find the fill plug. It’s usually located on the side or top of the transmission, often with a 14mm or 17mm hex head.
2. Remove the fill plug: Use a wrench to loosen and remove the fill plug.
3. Pour new fluid: Using a funnel, slowly pour the new transmission fluid into the fill hole. Refer to your owner’s manual for the correct fluid type and quantity.
4. Check fluid level: When the fluid starts to trickle out of the fill hole, stop pouring.
5. Replace the fill plug: Tighten the fill plug back into place using a torque wrench. Refer to your owner’s manual for the correct torque specification.

Final Checks and Clean-Up

1. Start the engine: Start the engine and allow it to idle for a few minutes.
2. Check for leaks: Inspect the transmission area for any signs of leaks.
3. Drive the car: Take the car for a short test drive, paying attention to how the transmission shifts.
4. Re-check fluid level: After the test drive, re-check the fluid level and top off as needed.
5. Clean up: Dispose of the old transmission fluid properly. Clean up any spills or drips with a clean rag.

Keeping Your BRZ in Top Condition

Changing your BRZ’s transmission fluid is a relatively simple procedure that can significantly impact your car’s performance and longevity. By following these steps and performing regular maintenance, you can ensure your BRZ continues to deliver the exhilarating driving experience it’s known for.

Answers to Your Most Common Questions

Q: How often should I change my BRZ’s transmission fluid?

A: Subaru recommends changing the transmission fluid every 30,000 miles or 3 years, whichever comes first. However, consider changing it more frequently if you frequently drive in harsh conditions or tow heavy loads.

Q: What type of transmission fluid should I use for my BRZ?

A: Refer to your BRZ’s owner’s manual for the specific type of transmission fluid recommended for your model year. Using the wrong type of fluid can damage your transmission.

Q: Can I change the transmission fluid myself?

A: While changing the transmission fluid is a relatively straightforward task, it requires some mechanical knowledge and tools. If you’re not comfortable working on your car, it’s best to have a qualified mechanic perform the service.

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

A: Neglecting transmission fluid changes can lead to various problems, including rough shifting, transmission damage, and reduced performance. It can also result in costly repairs.

Q: How can I tell if my transmission fluid needs to be changed?

A: Check the color and smell of the transmission fluid. Fresh fluid should be a light red or amber color and have a mild odor. If it’s dark brown or black and has a burnt smell, it’s likely time for a fluid change.
