Does the Subaru Ascent have a CVT transmission?
The Subaru Ascent does not use a CVT; it comes with an eight-speed automatic transmission instead.
Overview: engine and transmission pairing
The Ascent pairs its 2.4-liter turbocharged flat-four engine with an eight-speed automatic transmission. This setup delivers notable torque for a family SUV and provides traditional, stepped gear changes rather than the incessant gearing changes of a CVT. The combination is designed to balance strong acceleration with everyday practicality for families and cargo-hauling needs.
Transmission details and performance
Key characteristics of the Ascent’s transmission ecosystem include:
- Eight-speed automatic transmission (not a CVT)
- Engine: 2.4-liter turbocharged four-cylinder with robust torque
- Manual shift mode and/or paddle shifters for enhanced driver control
- Transmission tuned to work smoothly with all-wheel-drive drive characteristics
In contrast to the Ascent, several other Subaru models—such as the Impreza and Forester in certain trims—use Subaru’s CVT (Lineartronic) to emphasize fuel efficiency and smoothness in traditional commuting scenarios. The Ascent’s 8-speed automatic offers a more traditional driving feel, especially under load or when towing.
Why Subaru uses different transmissions across its lineup
Subaru designs its lineup to meet varying customer needs: turbocharged or higher-torque applications benefit from a sturdy automatic transmission with defined gear steps, while non-turbo, economy-focused models can leverage a CVT to maximize efficiency. This results in the Ascent opting for an eight-speed automatic to complement its performance-oriented, family-focused role.
Model years and trims
From its introduction in 2019 through the present, the Subaru Ascent has been paired with an eight-speed automatic transmission across all trims and model years. This pairing remains standard regardless of drivetrain configuration, with all-wheel drive typically standard or readily available.
Summary
The Subaru Ascent uses an eight-speed automatic transmission rather than a CVT. This setup supports the SUV’s turbocharged engine performance and towing capability, offering traditional gear changes and driver control that differ from the CVT-equipped Subaru models.
What is the CVT issue on the Subaru Ascent?
Common Subaru Ascent CVT problems include shuddering, hesitation, and slipping, which can be caused by software glitches, hydraulic sensor issues, or worn internal components. Other issues reported are loud noises, delayed acceleration, and overheating. These problems are often linked to an issue that can cause the CVT chain to slip, which may lead to a loss of power.
Common symptoms

- Shuddering, hesitation, or jerky movements: This is a common symptom that can be felt, especially during acceleration.
- Slipping gears: A sudden loss of power or feeling that the car is not accelerating as it should can indicate the CVT chain is slipping.
- Loud noise: A whining or droning sound coming from the transmission can signal worn pulley bearings.
- Delayed response: The engine may hesitate or lag before responding to the accelerator pedal.
- Transmission error lights: Warning lights, such as the Check Engine light, may turn on, and the vehicle could enter "limp mode" with reduced power.
- Overheating: The CVT can overheat, which can damage internal components.
Underlying causes

- WUV-07 Recall: Some 2019-2020 models are subject to a recall for a hydraulic sensor that can inaccurately measure fluid pressure, causing the CVT chain to slip.
- Wear and tear: Over time, the CVT chain and pulleys can wear out, especially with heavy use like towing or aggressive driving.
- Improper maintenance: Infrequent or neglected CVT fluid changes can lead to excessive wear and overheating because the old fluid loses its lubricating properties.
- Faulty components: Issues with solenoids in the valve body or other internal hardware can cause the transmission to malfunction.
What to do
- Check for recalls: See if your vehicle is affected by the WUV-07 recall and have the necessary repairs performed by a Subaru dealership free of charge.
- Perform regular maintenance: Follow Subaru's recommended maintenance schedule, and consider changing the CVT fluid more frequently than the recommended interval, such as every 30,000–40,000 miles, says this YouTube video and A&A, The Shop.
- Get professional diagnosis: If you experience any of the symptoms, have a certified technician diagnose the issue. A new transmission may be required in some cases, according to Facebook and Reddit posts.
Which Subaru models have no CVT transmission?
The main Subaru model without a CVT is the BRZ, which offers either a manual or a traditional automatic transmission. Subaru also produced some older models with traditional automatic transmissions, such as the 6-cylinder models of the Outback and Legacy up to the 2014 model year, and some WRX and Impreza trims are available with a manual transmission.
Models available with manual or non-CVT automatic transmissions
- Subaru BRZ: This is the primary model currently offered with a traditional automatic or manual transmission instead of a CVT.
- WRX: This performance model is available with a manual transmission.
- Impreza: Some models, particularly those with manual transmissions, may not use a CVT.
Older models with non-CVT transmissions
- Outback/Legacy (3.6R models): From the 2010-2014 model years, these models had a traditional 5-speed automatic transmission before switching to a CVT for 2015.
- Older models: Older Subaru models, like the Justy, were available with a CVT in the late 80s and 90s, but other transmissions were also available.
Why Subaru primarily uses CVTs
- Fuel efficiency: CVTs help Subaru meet its fuel economy and emissions goals.
- Cost-effectiveness: The CVT is a feasible option for Subaru to produce and develop cost-effectively.
- Simplicity: CVTs have a simpler design with fewer large moving parts.

Do all Subaru Ascents have a CVT?
Yes, every Subaru Ascent comes with a continuously variable transmission (CVT). The CVT is standard on all Ascent models and is a key part of its powertrain, which also includes an 8-speed manual mode and paddle shifters.
- The Ascent's Lineartronic® CVT is designed to work with the engine to keep it in its ideal power range for improved efficiency and performance.
- While Subaru has used CVTs in many models for years, it has been standard on all automatic models since 2014, with the exception of the BRZ sports car.
- The Ascent uses the same CVT as the automatic WRX, which has been refined with a reinforced transmission case and a new torque converter for a smoother ride.
What kind of transmission is in the Subaru Ascent?
The Subaru Ascent uses a Lineartronic® Continuously Variable Transmission (CVT), specifically the TR690 model. This type of transmission is a key feature across most automatic Subaru models and is known for providing fuel efficiency and smooth acceleration. It uses steel chains and pulleys to provide an unlimited number of gear ratios, rather than fixed gears. The Ascent's CVT also includes an eight-speed manual mode accessible via paddle shifters on the steering wheel.
