How do I know if my Subaru CVT is bad?
If you own a Subaru with a continuously variable transmission (CVT), it's important to be aware of the signs of a failing CVT. A bad CVT can lead to expensive repairs, so it's crucial to catch the problem early. In this article, we'll explore the key indicators that your Subaru's CVT may be on its way out.
Common Signs of a Bad Subaru CVT
Here are some of the most common symptoms that your Subaru's CVT is failing:
- Slipping or Shuddering: If the transmission slips or shudders during acceleration, it could be a sign of internal wear or damage within the CVT.
- Delayed Engagement: When you put the car in gear, there may be a noticeable delay before the transmission engages and the car starts moving. This could indicate a problem with the CVT.
- Whining or Grinding Noises: Strange noises coming from the transmission, such as whining, grinding, or humming, can signify issues with the CVT's internal components.
- Overheating: If the transmission is running hotter than normal, it could be a sign of a problem with the CVT's cooling system or internal components.
- Erratic RPM Behavior: The engine RPMs may fluctuate erratically, even when the vehicle's speed remains constant, which can indicate a CVT issue.
If you notice any of these symptoms, it's important to have your Subaru's CVT inspected by a qualified mechanic as soon as possible to prevent further damage and costly repairs.
Diagnosing a Bad Subaru CVT
To diagnose a bad CVT, a mechanic will typically perform a series of tests, including:
- Visual Inspection: The mechanic will visually inspect the CVT for any signs of leaks, damage, or wear.
- Fluid Analysis: The transmission fluid will be tested for signs of contamination or degradation, which can indicate internal issues.
- Diagnostic Scan: The mechanic will use a diagnostic tool to check for any error codes or other data that can help identify the problem.
- Road Test: The mechanic will take the vehicle for a test drive to observe the CVT's performance under various driving conditions.
Based on the results of these tests, the mechanic will be able to determine the root cause of the CVT issue and recommend the appropriate repair or replacement.
Preventing CVT Failure in Subarus
To help extend the life of your Subaru's CVT, it's important to follow the manufacturer's recommended maintenance schedule, which typically includes regular fluid changes and inspections. Additionally, avoiding aggressive driving, such as rapid acceleration and heavy towing, can help reduce the strain on the CVT and prevent premature failure.
How do I know if I need a new CVT transmission?
Some common problems to look out for with your CVT include: Transmission 'jerking', slipping, grinding or jumping during acceleration when the car is shifting gears. Noisy while driving – some customers have issues with a 'whining', 'clanging' or 'rattling' sound while driving especially with Nissan CVT's.
How much does it cost to replace a CVT transmission in a Subaru?
between $7,500 and $8,600
Subaru: The average replacement repair cost for a Subaru CVT transmission is between $7,500 and $8,600. Subaru's powertrain warranty covers the transmission for 5 years or 60,000 miles.
How do you test a CVT transmission?
While observing the Tiptronic indicator, step-shift the CVT from its lowest ratio to its highest (six or seven speeds), accelerating moderately after each shift but never exceeding 35 mph. Shift the transmission back down to 1st gear and gently apply the brake until the wheels come to a stop.
What are the signs of a failing CVT transmission?
They include:
- Delayed Acceleration. Your car may feel sluggish when you accelerate and try to get up to speed.
- Transmission Slipping.
- Juddering/Shuddering.
- Loss of Power.
- Overheating.
- Whining/Grinding Sounds.
- Reduced Fuel Efficiency.
- Transmission Fluid Leaks.
Will Subaru replace my CVT transmission?
All new Subaru vehicles include powertrain warranty coverage that lasts for 5 years or 60,000 miles, whichever comes first. This means that Subaru guarantees your CVT will last at least that long and promises to pay for the cost to repair or replace the transmission should it fail before that time.
Will a bad CVT transmission throw a code?
Often (though not always) a faulty transmission will trigger an engine diagnostic code and trip the Check Engine Light to let you know.
What years did Subaru have CVT transmission problems?
Subaru Legacy: 2010-2015 Models
The Subaru Legacy shares many of its components with the Outback. Thus, it's no surprise that similar model years—2010 to 2015—have similar issues. The CVT transmission problems were also among the most prominent.
How do I know if my Subaru CVT transmission is bad?
Here are some symptoms that may indicate a transmission problem in your Subaru:
- Delayed or rough gear shifting.
- Unusual noises, such as grinding, whining, or clunking.
- Slipping gears, where the engine revs but the car doesn't accelerate accordingly.
- Leaking transmission fluid or a burning smell.
Is there a recall for Subaru on transmissions?
Subaru of America, Inc. (Subaru) has initiated this safety and emissions Recall for certain 2019 - 2020 model year Ascent vehicles, 2020-2021 model year turbo Legacy vehicles, and 2020-2021 model year turbo Outback vehicles in which the Continuously Variable Transmission (CVT) chain may slip and/or break.
How long will Subaru CVT transmission last?
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.
