Are you experiencing slipping gears, rough shifting, or a burning smell in your 2008 Infiniti FX35? These could be signs of low transmission fluid. While the FX35 is known for its reliability, neglecting transmission fluid maintenance can lead to costly repairs. This comprehensive guide will walk you through the process of checking and topping off the transmission fluid in your 2008 FX35, ensuring smooth and efficient shifting for years to come.
Why Is Transmission Fluid Important?
Transmission fluid plays a crucial role in the smooth operation of your vehicle’s automatic transmission. It acts as a lubricant, coolant, and hydraulic fluid, ensuring gears engage properly, preventing wear and tear, and dissipating heat. Over time, transmission fluid breaks down, loses its effectiveness, and can lead to transmission failure if not replaced regularly.
When to Check Transmission Fluid
The 2008 FX35’s transmission fluid should be checked every 30,000 miles or annually, whichever comes first. However, if you notice any of the following symptoms, it’s a good idea to check the fluid level sooner:
- Slipping or delayed gear engagement: This indicates low fluid levels or a problem with the transmission itself.
- Rough shifting: A rough or jerky shift can be caused by low fluid levels or contaminated fluid.
- Burning smell: This is a sign of overheating, which could be caused by low fluid levels or a faulty transmission cooler.
- Transmission fluid leak: Any visible leaks should be addressed immediately.
Tools You’ll Need
Before you begin, gather the following tools and materials:
- New transmission fluid: Consult your owner’s manual for the recommended type and quantity of fluid for your FX35. Use only the specified fluid.
- Clean rags: For wiping spills and cleaning up any mess.
- Funnel: To safely pour the fluid into the transmission dipstick tube.
- Jack and jack stands: To lift the vehicle safely for access to the dipstick.
- Safety glasses: To protect your eyes from splashes.
- Gloves: To protect your hands from the fluid.
How to Check the Transmission Fluid Level
1. Park your vehicle on a level surface and engage the parking brake.
2. Warm up the engine: Run the engine for a few minutes to allow the transmission fluid to reach operating temperature.
3. Locate the transmission dipstick: The dipstick is typically located on the passenger side of the engine, near the firewall. It may have a yellow or orange handle.
4. Pull out the dipstick and wipe it clean with a rag.
5. Reinsert the dipstick fully and then pull it out again.
6. Check the fluid level: The fluid level should be between the “Full” and “Add” marks on the dipstick. If the level is low, you will need to add fluid.
How to Add Transmission Fluid
1. Locate the transmission fluid filler tube: The filler tube is usually located near the dipstick. It may be labeled with a “Trans” or “ATF” symbol.
2. Remove the filler cap: Use a wrench or your fingers to loosen and remove the cap.
3. Insert the funnel into the filler tube.
4. Carefully pour the new transmission fluid into the filler tube.
5. Check the fluid level frequently: Stop adding fluid when the level reaches the “Full” mark on the dipstick.
6. Replace the filler cap.
7. Start the engine and run it for a few minutes.
8. Check the fluid level again: If the level is low, repeat steps 4-7 until the fluid level is at the “Full” mark.
Important Considerations
- Never overfill the transmission: Overfilling the transmission can cause damage.
- Use the correct type of transmission fluid: Using the wrong type of fluid can damage your transmission.
- Inspect the transmission for leaks: If you see any leaks, have them repaired immediately.
- Consider a professional fluid change: If you are not comfortable performing this procedure yourself, take your vehicle to a qualified mechanic.
Keeping Your Transmission Healthy
Regular fluid checks and replacements are essential for a healthy transmission. Here are some additional tips to keep your transmission in top condition:
- Avoid harsh driving habits: Sudden acceleration and braking can put extra stress on your transmission.
- Have your transmission serviced regularly: Follow the manufacturer’s recommended maintenance schedule for fluid changes.
- Listen for unusual noises: Any unusual noises coming from your transmission should be investigated by a mechanic.
Time to Shift into High Gear
By following these steps and implementing good maintenance practices, you can keep your 2008 Infiniti FX35’s transmission running smoothly for many years to come. Remember, a well-maintained transmission ensures a more enjoyable driving experience and helps prevent costly repairs down the road.
