If you own a Subaru with a Continuously Variable Transmission (CVT), you may be wondering if Subaru recommends changing the CVT fluid. The answer is yes, Subaru does recommend changing the CVT fluid, and it’s important to follow the manufacturer’s recommendations to ensure the longevity and performance of your transmission.
Why is CVT Fluid Important?
CVT fluid is a specialized type of transmission fluid that is designed to lubricate and protect the components of a CVT. It helps to reduce friction, prevent wear and tear, and keep the transmission running smoothly. Over time, CVT fluid can break down and become contaminated with metal shavings and other particles. This can lead to decreased transmission performance and, eventually, transmission failure.
How Often Should You Change CVT Fluid?
Subaru recommends changing the CVT fluid every 30,000 to 60,000 miles, depending on your driving conditions. If you drive in severe conditions, such as in stop-and-go traffic or in extreme temperatures, you may need to change the fluid more frequently.
What are the Signs of Bad CVT Fluid?
There are several signs that may indicate that your CVT fluid needs to be changed, including:
- Slipping or shuddering transmission: This can be a sign that the fluid is low or contaminated.
- Delayed or rough shifting: This can also be a sign of low or contaminated fluid.
- Leaking transmission: If you see fluid leaking from your transmission, it’s important to have it checked by a mechanic as soon as possible.
- Burning smell: If you smell a burning smell coming from your transmission, it could be a sign that the fluid is overheating or contaminated.
How to Change CVT Fluid
Changing CVT fluid is a relatively simple process that can be done at home with the right tools and materials. Here are the steps:
1. Gather your materials: You will need new CVT fluid, a new transmission filter (if applicable), a drain pan, a funnel, and a wrench.
2. Locate the drain plug: The drain plug is usually located on the bottom of the transmission pan.
3. Drain the old fluid: Place the drain pan under the transmission and carefully remove the drain plug. Allow the old fluid to drain completely.
4. Replace the drain plug: Once the old fluid has drained, replace the drain plug and tighten it to the specified torque.
5. Remove the transmission pan: The transmission pan is usually held in place by bolts. Remove the bolts and carefully remove the pan.
6. Replace the transmission filter: If your transmission has a filter, it should be replaced at this time.
7. Clean the transmission pan: Use a clean rag to wipe away any dirt or debris from the transmission pan.
8. Install the transmission pan: Reinstall the transmission pan and tighten the bolts to the specified torque.
9. Fill the transmission with new fluid: Use a funnel to add new CVT fluid to the transmission. Fill the transmission to the specified level.
10. Check the fluid level: Start the engine and allow it to run for a few minutes. Then, check the fluid level and add more fluid if necessary.
Benefits of Changing CVT Fluid
Changing your CVT fluid regularly offers several benefits, including:
- Improved transmission performance: Fresh CVT fluid helps to lubricate and protect the transmission components, which can improve shifting and reduce noise.
- Extended transmission life: Changing the fluid helps to remove contaminants and prevent wear and tear, which can extend the life of your transmission.
- Reduced repair costs: By changing the fluid regularly, you can help to prevent costly transmission repairs.
When Not to Change CVT Fluid
There are some cases where you may not need to change the CVT fluid, such as:
- If your vehicle is new: Most new vehicles come with fresh CVT fluid that does not need to be changed for the first few years.
- If you have a sealed CVT: Some CVTs are sealed and do not require fluid changes.
Top Questions Asked
Q: How much does it cost to change CVT fluid?
A: The cost of changing CVT fluid varies depending on the make and model of your vehicle and the location of the service. Typically, it costs between $100 and $250.
Q: Can I change CVT fluid myself?
A: Yes, you can change CVT fluid yourself if you have the right tools and materials. However, it is important to follow the manufacturer’s instructions carefully.
Q: What happens if I don’t change CVT fluid?
A: If you do not change CVT fluid regularly, it can lead to decreased transmission performance, increased wear and tear, and eventually transmission failure.
