Should you service a Subaru CVT transmission?
Yes, it is generally recommended to service a Subaru continuously variable transmission (CVT) regularly to maintain its performance and longevity. Subaru CVTs require specific maintenance procedures and fluid changes at regular intervals to ensure they continue to function properly.
Understanding Subaru CVT Transmissions
Subaru vehicles have used CVT transmissions in many of their models since the early 2000s. Unlike traditional automatic transmissions with fixed gear ratios, a CVT uses a system of pulleys and belts to provide seamless, infinite gear changes. This design can provide improved fuel efficiency and smoother power delivery compared to a traditional automatic.
However, Subaru CVTs also have some unique maintenance requirements. The transmission fluid needs to be changed at regular intervals, typically every 30,000 to 60,000 miles, to prevent wear and ensure proper lubrication of the internal components.
Why Service a Subaru CVT?
- Fluid Changes: The CVT fluid is specially formulated and must be changed at the recommended intervals to prevent damage. Neglecting fluid changes can lead to premature wear and failure of the transmission.
- Preventative Maintenance: Regular servicing helps identify any potential issues early before they become major problems. This can extend the life of the CVT and avoid costly repairs down the road.
- Manufacturer Recommendations: Subaru strongly recommends following the maintenance schedule for CVT-equipped vehicles to maintain the warranty and ensure proper operation.
Neglecting CVT maintenance can result in a range of issues, including slipping, jerking, overheating, and even complete transmission failure. Staying on top of the recommended service intervals is crucial for the long-term health of a Subaru CVT.
How to Service a Subaru CVT
Servicing a Subaru CVT typically involves the following steps:
- Fluid Change: The CVT fluid must be drained and replaced with the specific Subaru-approved fluid at the recommended intervals.
- Filter Replacement: The transmission filter may also need to be replaced during a service, as specified in the owner's manual.
- Inspection: A technician will inspect the CVT for any signs of wear or damage, such as leaks, unusual noises, or slipping.
- Software Updates: In some cases, Subaru may release software updates for the CVT control module to improve performance or address any known issues.
It's important to have a Subaru-certified technician perform the CVT service to ensure it is done correctly and with the proper parts and fluids. Attempting DIY CVT maintenance can risk causing further damage if not done properly.
By staying on top of the recommended Subaru CVT service intervals, you can help ensure your transmission continues to operate smoothly and reliably for the life of your vehicle.
How do I keep my CVT transmission healthy?
Regular fluid changes, cautious driving habits, and prompt attention to any unusual symptoms will help ensure your CVT operates smoothly and remains reliable throughout its lifespan. Should you encounter any issues, consult a qualified mechanic for a thorough diagnosis and repair.
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.
Does a CVT transmission need to be serviced?
If your vehicle has a CVT transmission then you'll want to follow a regular maintenance schedule so you can continue to enjoy that smooth ride. Your local transmission service or dealer can tell you when you should have regular CVT transmission service if you are unsure.
What happens if CVT fluid is not changed?
Apart from overheating, old transmission fluid can lead to a buildup of sludge and debris that creates clogs. This not only further reduces the efficiency of the transmission but can lead to erratic shifting, delayed gear engagement, and in severe cases, total transmission failure.
How much does a CVT service 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.
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.
Does Subaru CVT transmission fluid need to be changed?
Follow Subaru's Recommendations
Subaru often suggests changing the transmission fluid at regular intervals, such as every 30,000 to 60,000 miles, depending on the model and transmission type.
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.
How to care for a Subaru CVT transmission?
The only regularly scheduled maintenance a Subaru CVT transmission requires routinely is an inspection of the fluid.
How do I know if my CVT transmission fluid needs replacing?
Other than the dreaded check engine light, if you observe delayed shifting, poor acceleration, slipping gears, or transmission whine, then you should consider having your transmission fluid changed or maybe even flushed.
