How to Change Transmission Fluid Infiniti Q50: Essential Tips You Can’t Miss

The Infiniti Q50 is a sleek and powerful luxury sedan, but like any vehicle, it requires regular maintenance to keep it running smoothly. One crucial aspect of maintenance is changing the transmission fluid. This guide will walk you through the process of how to change transmission fluid Infiniti Q50, ensuring you can keep your car performing at its best.

Why Change Transmission Fluid?

Transmission fluid is essential for the proper functioning of your car’s automatic transmission. It lubricates the gears, cools the system, and helps to prevent wear and tear. Over time, transmission fluid breaks down and loses its effectiveness. This can lead to a variety of issues, including:

• Rough shifting: You may notice your transmission shifting abruptly or hesitating between gears.
• Transmission slipping: The transmission may feel like it’s slipping or not engaging properly.
• Transmission overheating: The transmission may overheat, leading to damage.
• Reduced fuel efficiency: A worn-out transmission can decrease your gas mileage.

To avoid these problems, it’s crucial to change your transmission fluid at the recommended intervals. Infiniti recommends a fluid change every 30,000 miles or 3 years, whichever comes first. However, if you frequently drive in harsh conditions, such as extreme heat or cold, or if you tow heavy loads, you may need to change your transmission fluid more often.

What You’ll Need

Before you start, make sure you have all the necessary tools and materials:

• New transmission fluid: Consult your Infiniti owner’s manual for the correct type and quantity of fluid.
• Drain pan: This will catch the old transmission fluid.
• Torque wrench: This is essential for tightening bolts to the correct specifications.
• Wrench set: You’ll need a variety of wrenches to loosen and tighten bolts.
• Funnel: This will help you pour the new transmission fluid into the transmission.
• Gloves: Protect your hands from the hot fluid.
• Safety glasses: Protect your eyes from any splashes.
• Clean rags: For wiping up spills and cleaning parts.

Step-by-Step Guide to Changing Transmission Fluid in an Infiniti Q50

1. Warm Up the Transmission:

Start by warming up your Infiniti Q50’s transmission. Drive it for about 10 minutes to allow the fluid to circulate and reach operating temperature. This will help loosen the fluid and make it easier to drain.

2. Park on a Level Surface:

Park your car on a level surface and engage the parking brake. Ensure the car is in Park (P) for automatic transmissions.

3. Locate the Transmission Pan:

The transmission pan is located on the bottom of the transmission. You can usually find it by following the transmission lines.

4. Prepare for Drainage:

Place the drain pan underneath the transmission pan. It’s a good idea to use a piece of cardboard or a drop cloth to protect the surrounding area from any spills.

5. Remove the Drain Plug:

Locate the drain plug on the transmission pan. It’s usually a square or hexagonal bolt. Use a wrench to loosen and remove the drain plug. Be careful as the fluid will be hot.

6. Drain the Transmission Fluid:

Let the old transmission fluid drain completely into the drain pan. This may take a few minutes.

7. Replace the Drain Plug:

Once the fluid has drained, clean the drain plug and the surrounding area. Reinstall the drain plug and tighten it to the correct torque specification. Consult your owner’s manual for the correct torque value.

8. Remove the Transmission Pan:

Now, remove the transmission pan. This may require removing other bolts or screws depending on your model.

9. Clean the Pan and Filter:

Thoroughly clean the inside of the pan and the transmission filter. You can use a wire brush or a shop vac to remove any debris.

10. Install New Filter:

Replace the transmission filter with a new one. Ensure the new filter is correctly installed and secured.

11. Reinstall the Transmission Pan:

Replace the transmission pan and tighten the bolts to the correct torque specification.

12. Fill the Transmission with New Fluid:

Locate the transmission fluid dipstick. Remove it and pour the new transmission fluid into the transmission until it reaches the “full” mark on the dipstick.

13. Check Fluid Level:

Start the engine and let it idle for a few minutes. Then, check the transmission fluid level again and add more fluid as needed.

14. Test Drive:

Take your Infiniti Q50 for a test drive to ensure the transmission is shifting smoothly.

15. Final Check:

Once you’ve completed the test drive, check the transmission fluid level one last time to ensure it’s at the correct level.

Tips for Success
