How often should you change Subaru CVT transmission fluid?
The recommended interval for changing the continuously variable transmission (CVT) fluid in a Subaru vehicle is typically every 30,000 miles or 24 months, whichever comes first. This maintenance is crucial to ensure the longevity and proper functioning of the CVT system in your Subaru.
Understanding Subaru CVT Transmission Fluid
Subaru vehicles are equipped with a continuously variable transmission (CVT), which uses a system of belts and pulleys to provide a seamless and efficient power delivery. The CVT fluid plays a vital role in lubricating and cooling the internal components of this transmission, preventing wear and tear over time.
Unlike traditional automatic transmissions, which have a fixed set of gears, the CVT in a Subaru is designed to continuously adjust the gear ratio to optimize power and fuel efficiency. This unique design requires specialized CVT fluid that is formulated to withstand the high temperatures and pressures generated within the transmission.
Recommended Fluid Change Interval
Subaru recommends changing the CVT fluid every 30,000 miles or 24 months, whichever comes first. This interval is based on the manufacturer's extensive testing and research to ensure the optimal performance and longevity of the CVT system.
Failing to change the CVT fluid at the recommended intervals can lead to several issues, including:
- Increased wear and tear on the internal components, leading to premature failure
- Reduced efficiency and power delivery from the transmission
- Potential damage to the CVT system, which can be costly to repair
It's important to note that the recommended fluid change interval may vary slightly depending on your driving conditions and usage. For example, if you frequently tow heavy loads or drive in mountainous terrain, you may need to change the fluid more frequently to ensure optimal protection for your CVT.
Performing the Fluid Change
Changing the CVT fluid in a Subaru should be done by a qualified technician, as it requires specialized tools and procedures to properly drain, flush, and refill the system. Attempting to perform this maintenance yourself without the proper knowledge and equipment can lead to further damage to the transmission.
During the fluid change, the technician will also inspect the CVT system for any signs of wear or damage, and may recommend additional maintenance or repairs if necessary.
By following Subaru's recommended CVT fluid change interval and having the work performed by a qualified professional, you can help ensure the long-term health and performance of your Subaru's transmission.
How much does a CVT transmission flush cost?
On average, you can expect to pay between $350 to $400 for a CVT fluid change in the United States. This price range takes into account various factors such as the type of vehicle, location, and the specific dealership or service center you choose.
How long will a CVT transmission last in a Subaru?
There is a fair chance your Subaru CVT will last well beyond 60,000 miles as long as you stick to the factory-recommended maintenance schedule and take care not to overfill your transmission fluid.
How often should I change the transmission fluid in my Subaru Outback?
The Subaru CVT transmission does not require regular fluid replacement, however it is recommended to check the fluid every 30000 miles. It should only be replaced at these intervals if the fluid appears dirty, very low, or contaminated by water.
How often should I change my Forester CVT fluid?
Subaru CVT Transmission Fluid Service Special
For instance, Transmission Fluid Services vary from make to model and driver to driver, but typically the range is once every 30,000 to 60,000 miles.
How many years does CVT transmission fluid last?
two to five years
Generally, it is advisable to change the transmission fluid every 30,000 to 60,000 miles or approximately every two to five years.
How often does CVT fluid need to be changed?
every 30,000 to 60,000 miles
Most manufacturers recommend changing the CVT transmission fluid every 30,000 to 60,000 miles. This interval is designed to ensure that the fluid is in good condition and prevents potential transmission damage. However, this interval may vary depending on the type of vehicle, your driving style, and the vehicle's age.
Can a CVT transmission last 300000 miles?
Despite their durability, Honda CVTs can encounter issues; however, with proper care, they can help owners exceed 300,000 miles on their vehicles.
Does CVT fluid need to be changed on a Subaru?
Just like a traditional automatic gearbox, the CVT gearbox will need a transmission flush occasionally. If the fluid isn't changed inside the transmission eventually, it can break down too far to lubricate the metal gears as they mesh together, and allow the transmission to sustain serious damage.
What years did Subaru have CVT problems?
The models and years that were affected mainly by transmission issues are:
- Crosstrek, 2013 – 2015.
- Crosstrek Hybrid, 2014 – 2015.
- Forester (2.0 and 2.5 liter engines), 2014 – 2015.
- Impreza, 2012 – 2015.
- Legacy, 2010 – 2015.
- Legacy 3.6L V6, 2015.
- Outback, 2010 – 2015.
- Outback 3.6L V6, 2015.
What happens if you don't change CVT fluid?
Old, degraded oil can't provide adequate lubrication, leading to increased friction and, consequently, overheating. When the temperature gets too hot (transmission fluid itself overheats when temperatures reach higher than 200 degrees Fahrenheit), components begin to warp, break, and suffer severe damage.
