How to Check and Adjust the Transmission Fluid Level in Your INFINITI

Maintaining the proper transmission fluid level is essential for the smooth operation and longevity of your INFINITI vehicle. Transmission fluid lubricates gears, cools the system, and ensures proper shifting. Low or dirty fluid can lead to slipping gears, overheating, or costly transmission damage. This comprehensive guide will walk you through checking and adjusting your INFINITI’s transmission fluid safely and effectively.

Why Checking Transmission Fluid Matters

Transmission fluid plays a critical role in your INFINITI’s performance:

• Lubricates internal components to reduce wear and tear.
• Helps maintain proper gear shifting and smooth acceleration.
• Prevents overheating by carrying away excess heat from the transmission.
• Extends the lifespan of your transmission system.

Signs Your Transmission Fluid May Need Attention

• Delayed or rough gear shifts.
• Burning smell coming from the transmission.
• Transmission slipping or unusual noises.
• Dashboard warning lights related to transmission or fluid temperature.
• Fluid appears dark or has a burnt smell when checked.

How to Check Transmission Fluid in Your INFINITI

Most modern INFINITI vehicles have a sealed transmission system, but models with a traditional dipstick allow for manual fluid checks. Follow these steps:

1. Warm Up the Vehicle: Drive your INFINITI for 5–10 minutes to bring the transmission to operating temperature.
2. Park on Level Ground: Ensure the vehicle is in park (P) with the engine running and parking brake engaged.
3. Locate the Dipstick: Check your owner’s manual for the exact location. Typically, it is near the back of the engine bay.
4. Check Fluid Level: Remove the dipstick, wipe it clean, reinsert fully, then remove it again. Observe the fluid level — it should be within the marked range.
5. Inspect Fluid Quality: Healthy transmission fluid is typically bright red or pink and clear. Dark, brown, or burnt-smelling fluid indicates it’s time for a change.

How to Adjust or Add Transmission Fluid

1. Select the Correct Fluid: Use only the recommended INFINITI transmission fluid specified in your owner’s manual.
2. Add Fluid Gradually: Use a funnel to add small amounts at a time, checking the level frequently to avoid overfilling.
3. Recheck the Level: After adding fluid, repeat the dipstick check to ensure the level is correct.
4. Test Drive: Take a short drive to allow the fluid to circulate and recheck the level once more to confirm proper adjustment.

Model-Specific Tips for INFINITI Vehicles

Different INFINITI models such as the QX80, QX60, Q50, and QX55 may have unique transmission systems. Some newer models have sealed transmissions and require dealer service for fluid checks or adjustments. Always refer to your owner’s manual for model-specific instructions to avoid damage.

Transmission Maintenance Best Practices

• Check fluid levels at regular intervals recommended in your INFINITI maintenance schedule.
• Replace transmission fluid according to the manufacturer’s timeline.
• Inspect for leaks under the vehicle and around transmission lines.
• Use certified INFINITI transmission fluid to maintain warranty compliance.
