Your car’s transmission is one of its most critical components. The transmission ensures that the power from the engine gets to the wheels, and it’s responsible for shifting gears. In recent years, many cars have switched to continuously variable transmissions (CVT), which are known for their fuel efficiency and smooth operation. However, these transmissions require special maintenance, including regular CVT transmission fluid changes. In this post, we’ll discuss what CVT transmission fluid is, why it’s essential to change it, and how to do it.
- What is CVT Transmission Fluid?
CVT transmission fluid is a type of specialized lubricant designed for use in continuously variable transmissions. These transmissions work differently than traditional automatic or manual transmissions, and the fluid used to lubricate and cool them is different as well.
CVT transmission fluid contains specific additives to protect the transmission’s metal parts and reduce friction. It also has a unique formulation that allows it to handle the high heat generated by CVT transmissions. Most importantly, CVT transmission fluid contains detergents that help keep the transmission clean and free of debris.
- Why is CVT Transmission Fluid Change Important?
Like all transmission fluids, CVT transmission fluid breaks down over time. As it does, it loses its ability to protect the transmission’s metal parts and reduce friction. Old, worn-out fluid can also cause the transmission to overheat, which can lead to costly damage.
Regular CVT transmission fluid changes are crucial to maintaining the transmission’s health and longevity. The transmission manufacturer will specify the recommended interval for changing the fluid in your car’s owner’s manual. Most manufacturers recommend changing the fluid every 60,000 to 100,000 miles. However, it’s always best to follow the specific guidelines for your car.
- Signs that Your CVT Transmission Fluid Needs Changing
If you’re not sure when the last time you changed your car’s CVT transmission fluid was, there are some signs to watch out for that may indicate it’s time for a change. Here are a few signs to look out for:
- Transmission slipping or difficulty shifting gears: If your transmission is slipping or having difficulty shifting gears, it could be a sign that the fluid is worn out and no longer able to protect the transmission’s metal parts.
- Noisy transmission: If you notice unusual noises coming from your transmission, it could be a sign that the fluid is dirty or contaminated.
- Burnt smell: If you smell a burnt odor coming from your car, it could be a sign that the transmission fluid is overheating and breaking down.
- Fluid color: CVT transmission fluid is typically pink or red. If the fluid is dark, brown, or black, it’s a sign that it’s contaminated and needs to be changed.
If you notice any of these signs, it’s essential to have your car inspected by a mechanic to determine whether a CVT transmission fluid change is necessary.
- How to Change CVT Transmission Fluid?
Changing CVT transmission fluid is a bit different than changing traditional automatic or manual transmission fluid. It’s important to follow the specific guidelines for your car outlined in the owner’s manual. Here’s a general overview of the steps involved in changing CVT transmission fluid:
Step 1: Warm up the transmission
To ensure that the old fluid drains out completely, it’s essential to warm up the transmission by driving the car for a few minutes.
Step 2: Locate the drain and fill plugs
CVT transmissions Step 2: Locate the drain and fill plugs
CVT transmissions have a drain plug and a fill plug that are typically located on the transmission pan. The pan is located underneath the car, so you’ll need to jack up the car and support it on jack stands to access it.
Step 3: Drain the old fluid
Place a drain pan underneath the transmission pan and remove the drain plug. Allow the old fluid to drain out completely.
Step 4: Replace the transmission filter
While the old fluid is draining, it’s a good idea to replace the transmission filter. The filter is typically located inside the transmission pan and can be easily removed with a wrench or socket.
Step 5: Refill with new fluid
Once the old fluid has drained out, replace the drain plug and fill the transmission with new CVT transmission fluid. Use a funnel to avoid spills and overfilling.
Step 6: Check the fluid level
Start the car and let it idle for a few minutes to allow the new fluid to circulate through the transmission. Then, check the fluid level using the dipstick or level indicator on the transmission.
Step 7: Test drive the car
Take the car for a test drive to ensure that the transmission is shifting smoothly and there are no leaks.
It’s important to note that CVT transmission fluid changes can be more complex than traditional transmission fluid changes. In some cases, it may be necessary to bring your car to a professional mechanic to have the fluid changed.
- Conclusion
Regular CVT transmission fluid changes are critical to maintaining the health and longevity of your car’s transmission. Old, worn-out fluid can cause the transmission to overheat and fail, leading to costly repairs. By following the recommended fluid change intervals in your car’s owner’s manual and keeping an eye out for signs of worn-out fluid, you can help ensure that your car’s transmission operates smoothly and efficiently for years to come. If you’re not comfortable changing the fluid yourself, be sure to bring your car to a professional mechanic for this important maintenance task.
