Warning: Don’t Neglect Your CVT Fluid! How Often You Should Replace It in Your Subaru

Summary

  • CVT fluid is a specialized lubricant designed to withstand the unique demands of a CVT transmission.
  • How much does it cost to replace CVT fluid in a Subaru.
  • How can I check the CVT fluid level in my Subaru.

Maintaining your Subaru’s Continuously Variable Transmission (CVT) is crucial for its longevity and performance. One of the most important aspects of CVT maintenance is replacing the fluid at regular intervals. But how often should you replace CVT fluid in a Subaru?

Understanding CVT Fluid

CVT fluid is a specialized lubricant designed to withstand the unique demands of a CVT transmission. It plays several vital roles, including:

  • Reducing friction between moving parts
  • Transferring power between the engine and wheels
  • Cooling the transmission components
  • Protecting against wear and tear

Subaru recommends replacing CVT fluid according to the following schedule:

  • 2010-2012 Impreza, Legacy, Outback, and Tribeca: 60,000 miles or 5 years
  • 2013-2019 Impreza, Legacy, Outback, and Tribeca: 105,000 miles or 7 years
  • 2014-Present Forester: 105,000 miles or 7 years
  • 2017-Present Ascent: 105,000 miles or 7 years

Factors Affecting Replacement Intervals

The recommended replacement intervals are just guidelines. Several factors can influence how often you need to replace CVT fluid, such as:

  • Driving conditions: Frequent stop-and-go driving or towing heavy loads can put extra stress on the CVT fluid.
  • Climate: Extreme temperatures can affect the fluid’s viscosity and lifespan.
  • Mileage: Higher mileage vehicles may require more frequent fluid changes.

Signs of CVT Fluid Problems

If you notice any of the following symptoms, it may be time to replace your CVT fluid:

  • Shifting problems: Difficulty shifting gears or slipping out of gear
  • Noise: Unusual noises from the transmission
  • Shuddering: Vibrations during acceleration or deceleration
  • Burning smell: A burnt odor coming from the transmission
  • Leaks: Visible fluid leaks from the transmission

DIY vs. Professional Replacement

Replacing CVT fluid is a complex procedure that requires specialized tools and knowledge. While some experienced DIYers may attempt it, it’s generally recommended to have the fluid replaced by a qualified mechanic.

Benefits of Regular CVT Fluid Replacement

Regular CVT fluid replacement offers several benefits, including:

  • Improved transmission performance: Fresh fluid ensures smooth shifting and reduces wear and tear.
  • Extended transmission life: Properly maintained CVTs can last significantly longer.
  • Reduced repair costs: Timely fluid changes can prevent costly transmission repairs.
  • Increased fuel efficiency: Well-lubricated transmissions can improve fuel consumption.

CVT Fluid Replacement Process

The CVT fluid replacement process typically involves:

1. Draining the old fluid
2. Removing and inspecting the CVT filter
3. Replacing the filter with a new one
4. Filling the transmission with new fluid
5. Checking the fluid level and adjusting as necessary

Conclusion: Maintaining Your CVT’s Health

Replacing CVT fluid at the recommended intervals is essential for the health and longevity of your Subaru’s transmission. By following the guidelines and addressing any signs of fluid problems, you can ensure your vehicle continues to perform optimally for years to come.

Basics You Wanted To Know

Q: Can I use any type of fluid in my Subaru’s CVT?
A: No, it’s crucial to use the specific type of CVT fluid recommended by Subaru. Using the wrong fluid can damage the transmission.

Q: How much does it cost to replace CVT fluid in a Subaru?
A: The cost can vary depending on the year, model, and location. Typically, it ranges from $200 to $400.

Q: Can I drive my Subaru with low CVT fluid?
A: No, driving with low CVT fluid can cause severe damage to the transmission. If you suspect low fluid levels, have it checked and replaced immediately.

Q: What happens if I don’t replace CVT fluid regularly?
A: Neglecting CVT fluid replacement can lead to premature transmission failure, costly repairs, and reduced vehicle performance.

Q: How can I check the CVT fluid level in my Subaru?
A: Refer to your owner’s manual for specific instructions on checking the CVT fluid level. It typically involves checking the fluid level on the transmission dipstick.
