Continuously variable transmissions (CVTs) are becoming increasingly popular in modern cars, offering smooth acceleration and fuel efficiency. However, unlike traditional automatic transmissions, CVT fluid needs to be changed regularly to ensure optimal performance and longevity. This article will guide you through the process of changing your car’s CVT transmission fluid.
Understanding CVT Transmission Fluid
CVT transmission fluid is specifically designed for the unique operating conditions of a CVT. It differs from conventional automatic transmission fluid in its viscosity, friction modifiers, and thermal stability. Using the wrong type of fluid can damage your transmission, leading to costly repairs.
Materials You’ll Need
- CVT transmission fluid⁚ Consult your car’s owner’s manual for the recommended type and quantity.
- Drain pan⁚ A large pan to catch the old fluid.
- Torque wrench⁚ To tighten the drain plug and fill plug to the correct specifications.
- New drain plug washer⁚ Ensure a tight seal.
- Wrench or socket⁚ To remove and tighten the drain and fill plugs.
- Funnel⁚ To pour the new fluid into the transmission.
- Gloves⁚ To protect your hands from the hot fluid.
- Safety glasses⁚ To protect your eyes.
- Jack and jack stands⁚ To safely raise the vehicle.
- Rag or shop towel⁚ To clean up spills.
Steps to Change CVT Transmission Fluid
1. Prepare Your Vehicle
- Park your car on a level surface and engage the parking brake.
- Allow the engine to cool down completely before proceeding.
- Locate the CVT transmission fluid dipstick or fill plug, which is usually near the transmission pan.
2. Drain the Old Fluid
- Place the drain pan underneath the transmission.
- Using a wrench or socket, carefully loosen and remove the drain plug.
- Let the old fluid drain completely into the pan.
3. Replace the Drain Plug
- Clean the drain plug and the surrounding area.
- Install a new drain plug washer.
- Tighten the drain plug to the specified torque using a torque wrench.
4. Fill with New Fluid
- Locate the CVT transmission fluid fill plug, which is usually near the drain plug.
- Using a funnel, slowly pour the new fluid into the transmission until the fluid level reaches the full mark on the dipstick.
- Check the fluid level again after starting the engine and running it for a few minutes. Top off as needed.
5. Double-Check for Leaks
- Inspect the drain plug and fill plug areas for leaks.
- Start the engine and run it for a few minutes to ensure proper fluid circulation.
- Check the fluid level again after the engine has been running.
Important Considerations
- Consult your owner’s manual⁚ Always refer to your car’s owner’s manual for specific instructions and recommendations on changing CVT transmission fluid.
- Use the correct fluid⁚ Using the wrong type of fluid can damage your transmission.
- Safety first⁚ Always wear safety glasses and gloves when working with hot fluids.
- Regular maintenance⁚ It’s essential to change your CVT transmission fluid at the recommended intervals to ensure optimal performance and longevity.
Conclusion
Changing your car’s CVT transmission fluid is a crucial maintenance task that helps to keep your transmission running smoothly and efficiently. By following the steps outlined above, you can perform this task safely and effectively. Remember to consult your owner’s manual for specific instructions and recommendations related to your vehicle.
