Key points
- If the fluid level is below the “MIN” mark, add CVT fluid using a funnel.
- Filling CVT fluid is a relatively straightforward task that can be completed in a few simple steps.
- Signs of a CVT fluid leak include fluid stains under the vehicle, a burning smell, and difficulty shifting gears.
Continuously Variable Transmissions (CVTs) have become increasingly popular in modern vehicles due to their efficiency and smooth driving experience. However, like any other automotive component, CVTs require proper maintenance to ensure optimal performance. One crucial aspect of CVT maintenance is filling the fluid, which can be a daunting task for some. This comprehensive guide will provide a step-by-step tutorial on how to fill CVT fluid, ensuring you can tackle this task with confidence.
Tools and Materials
Before you begin, gather the necessary tools and materials:
- CVT fluid (check your vehicle’s owner’s manual for the recommended type and quantity)
- Funnel
- Rags or paper towels
- Container for used fluid (optional)
- Torque wrench
- Safety glasses
Safety Precautions
- Park the vehicle on a level surface and engage the parking brake.
- Allow the engine to cool down completely before starting any work.
- Wear safety glasses to protect your eyes from any splashing fluid.
- Do not smoke or work near open flames, as CVT fluid is flammable.
Step 1: Locate the CVT Fluid Dipstick
Open the hood and locate the CVT fluid dipstick. It is usually labeled with “CVT Fluid” or “Transmission Fluid.”
Step 2: Check the Fluid Level
Pull out the dipstick, wipe it clean with a rag, and reinsert it fully. Remove the dipstick again and check the fluid level. It should be between the “MIN” and “MAX” marks on the dipstick.
Step 3: Add Fluid if Necessary
If the fluid level is below the “MIN” mark, add CVT fluid using a funnel. Pour the fluid slowly, checking the level frequently until it reaches the “MAX” mark.
Step 4: Reset the Fluid Counter
Some vehicles have a CVT fluid counter that needs to be reset after adding fluid. Refer to your vehicle’s owner’s manual for specific instructions on how to do this.
Step 5: Reinstall the Dipstick
Once the fluid level is correct, push the dipstick back into its tube and ensure it is fully secured.
Step 6: Inspect for Leaks
Start the engine and let it idle for a few minutes. Check under the vehicle for any leaks from the CVT. If you notice any leaks, tighten the drain plug or seek professional assistance.
Step 7: Check the Fluid Level Again
Drive the vehicle for a short distance and then check the fluid level again using the dipstick. Make sure the level is still within the “MIN” and “MAX” marks.
Final Thoughts
Filling CVT fluid is a relatively straightforward task that can be completed in a few simple steps. By following this guide carefully, you can ensure that your CVT is properly serviced and functioning optimally. Regular maintenance is essential for extending the lifespan of your transmission and preventing costly repairs in the future.
