To install AX5 transmission fluid, park on a level surface, locate and remove the drain plug, drain the old fluid, inspect and replace the plug, discover the fill plug, add new fluid, check the level, and test drive. Follow manufacturer guidelines for proper fluid type and quantities.

This step by step guide will walk you through installing AX5 transmission fluid, providing you with the knowledge and confidence to perform this maintenance task yourself.

How to install ax5 Transmission Fluid successfully?

1. Gather the Necessary Tools and Materials:

  • Safety gloves and goggles
  • Jack and Jack stands
  • Drain pan
  • Ratchet set
  • Socket wrench
  • Funnel
  • New transmission fluid (AX5-compatible)

2. Prepare Your Vehicle:

Ensure your vehicle is parked on a level surface and the engine is turned off. Engage the parking brake for added safety.

Prepare Your Vehicle

For additional access, you may need to raise the front of the vehicle using a jack and secure it with jack stands.

3. Find the Drain Plug:

Crawl under your vehicle and locate the transmission’s drain plug. It is typically positioned on the bottom of the transmission pan. Place the drain pan underneath to catch the old fluid.

4. Remove the Drain Plug:

Carefully loosen and remove the drain plug using the appropriate socket and ratchet. Allow the old transmission fluid to drain completely into the drain pan.

Remove the Drain Plug

5. Inspect and Clean the Drain Plug:

While the fluid is draining, inspect the drain plug for any metal shavings or debris. Clean the plug thoroughly with a lint-free cloth or paper towel.

6. Replace the Drain Plug:

Once the old fluid has drained, reinstall the drain plug and tighten it securely. Be careful not to over-tighten, as this could damage the threads.

7. Locate the Transmission Fill Plug:

Locate the transmission fill plug on the side of the transmission. It is usually positioned higher than the drain plug. If needed, consult your vehicle’s manual for the exact location.

8. Remove the Fill Plug:

Gently loosen and remove the fill plug using the appropriate socket and ratchet. It will allow air to escape while you add the new fluid.

9. Add New Transmission Fluid:

Using a funnel, carefully pour the new AX5 transmission fluid into the transmission through the fill hole.

Refer to your vehicle’s manual for the recommended quantity of liquid. Start with a conservative amount and check the fluid level as you go.

10. Check the Fluid Level:

After adding fluid, allow it to settle for a few minutes. Reinsert the fill plug and tighten it securely.

Start your vehicle’s engine and let it run for a few minutes. Shift through all gears, including Park and Neutral.

Check The Fluid Level

Then, with the engine running, check the transmission fluid level using the dipstick (if applicable) or the fill hole. Add more fluid if necessary to achieve the proper level.

11. Clean Up:

Once you’re satisfied with the fluid level, turn off the engine. Clean up any spills or drips, and properly dispose of the old transmission fluid following local regulations.

12. Test Drive:

Lower the vehicle from the jack stands and take it for a test drive. Pay attention to the gear shifts and listen for any unusual noises. If everything feels and sounds normal, you’ve successfully installed the new AX5 transmission fluid.

What Are the Benefits of Using ax5 Transmission Fluid?

1. Enhanced Lubrication:

AX5 transmission fluid is formulated with additives that provide superior lubrication to the transmission’s components.

Proper lubrication reduces friction and wear, which helps extend the lifespan of gears, synchronizers, bearings, and other moving parts. It, in turn, promotes smoother gear shifts and optimal transmission performance.

2. Improved Cooling:

Manual transmissions generate heat during operation, especially in demanding conditions such as towing or off-roading.

AX5 transmission fluid contains additives that aid in dissipating heat and maintaining appropriate operating temperatures. By preventing overheating, the fluid helps avoid potential damage to the transmission.

3. Seal Protection:

The seals within the transmission play a critical role in preventing fluid leaks and maintaining internal pressure.

AX5 transmission fluid contains seal conditioners that help keep the seals pliable and prevent them from deteriorating over time. It promotes better sealing and reduces the risk of leaks.

4. Smoother Gear Shifts:

Manual transmissions rely on precise synchronization between gears to enable smooth gear shifts.

AX5 transmission fluid contains additives that aid in synchronizer function, ensuring smoother and more effortless shifting between gears. It contributes to a more enjoyable and controlled driving experience.

5. Reduced Wear:

High-quality transmission fluid, such as AX5, minimizes wear and tear on internal transmission components. The additives in the fluid create a protective barrier that reduces metal-to-metal contact and prevents premature wear, ultimately prolonging the life of the transmission.

6. Improved Fuel Efficiency:

Proper lubrication and reduced friction result in improved mechanical efficiency. When the transmission operates smoothly, there is less energy loss due to friction, leading to better fuel efficiency and potentially lower operating costs over time.

7. Longevity:

Regularly using AX5 transmission fluid, as recommended by the manufacturer, helps maintain the overall health of the transmission. Proper lubrication, cooling, and protection make the transmission more likely to operate efficiently and last longer, saving you from costly repairs or replacements.

8. Compatibility:

AX5 transmission fluid is formulated to meet the specific requirements of manual transmissions, ensuring optimal compatibility with the transmission’s design and materials. Using the correct fluid type minimizes the damage risk and provides consistent performance.

9. Peace of Mind:

By using the recommended AX5 transmission fluid, you can have confidence that your transmission receives the proper protection and care. This peace of mind creates a more enjoyable driving experience and reduces the likelihood of unexpected transmission-related issues.

Frequently Asked Question:

1. Is it normal to find metal shavings on the drain plug?

Due to regular wear and tear, some metal shavings on the drain plug are expected. Excessive shavings or chunks could indicate a problem and should be inspected further.

2. Can I reuse the drain plug washer?

Replacing the drain plug washer with a new one during each fluid change is recommended to ensure a proper seal and prevent leaks.

3. What if I’m unable to access the fill or drain plugs?

If you encounter difficulty reaching the plugs, consider seeking assistance from a professional mechanic to avoid damaging components or causing leaks.

4. Can I mix different brands of transmission fluid?

It’s generally best to avoid mixing different brands of transmission fluid. Stick to one brand and type recommended by the manufacturer for consistent performance.

5. Is it necessary to perform a test drive after installing the new fluid?

Yes, a test drive allows you to verify that the transmission is shifting smoothly through all gears. Listen for unusual noises or vibrations and ensure proper functionality.


Installing AX5 transmission fluid is a straightforward process that involves draining the old fluid, inspecting the drain plug, refilling with new fluid, and ensuring proper fluid levels.

Regular fluid changes using the recommended fluid type contribute to smoother gear shifts, improved lubrication, and enhanced transmission performance.

By following the step-by-step guide and manufacturer’s specifications, you can successfully install an AX5 transmission fluid, promoting the longevity and reliable operation of your manual transmission.

Consulting a professional mechanic is always a viable option if you need more clarification or are uncomfortable with performing the task.
