What type of CVT transmission does Subaru use?
Subaru uses the Lineartronic CVT, a chain-driven design that substitutes a traditional rubber belt with a steel chain to vary gearing and deliver smooth power delivery across its all-wheel-drive lineup.
What is Lineartronic?
Lineartronic is Subaru's branding for its continuously variable transmission. It uses a chain to connect the pulleys and adjust the gear ratio continuously, enabling smooth acceleration and improved efficiency, especially when paired with Subaru's all-wheel-drive system. The design aims to balance responsive driving feel with fuel economy across a range of models.
How it works
The system alters the effective diameter of two variable pulleys connected by a steel chain. As engine speed and load change, the transmission continuously adjusts pulley radii to provide a seamless range of gear ratios. Some models offer a manual or sport mode that simulates stepped gear changes, while others prioritize invisible, continuous adjustment for a smooth experience.
Chain vs. belt CVTs: What makes Subaru different
Compared with belt-type CVTs used by many manufacturers, Subaru's Lineartronic relies on a chain mechanism, which proponents say offers stronger torque handling and durability under AWD usage. Critics note that all CVTs can exhibit a droning feel at certain throttle points; Subaru tunes software to minimize this sensation and provide a more direct, confident acceleration feel.
In practice, the chain design supports Subaru's emphasis on predictable, efficient performance across its crossover and sedan lineup, especially during low-speed starts and gradual acceleration.
Here are the defining characteristics of Subaru's Lineartronic CVT:
- Chain-driven design rather than a traditional rubber belt
- Broad, continuously variable ratio range for efficient operation across speeds
- Strong integration with Subaru's all-wheel-drive system for stable handling
- Throttle response tuned for smooth, refined acceleration; some models include a manual/sport mode
- Designed to minimize CVT droning and maximize daily drivability
In summary, these features contribute to a smooth, efficient driving experience that complements Subaru's AWD-focused lineup.
Maintenance and reliability considerations
As with any CVT, maintenance matters. Subaru recommends using the correct CVT fluid and following the service intervals listed in the owner's manual. Regular fluid changes and checks for leaks or unusual noises can help extend life, and drivers who frequently tow or drive in harsh conditions should follow dealership guidance on service frequency. Reliability can vary with mileage and usage, but the Lineartronic design is positioned to offer consistent performance when properly maintained.
Summary
Subaru's transmission strategy relies on Lineartronic, a chain-type CVT designed to deliver smooth, efficient performance across its all-wheel-drive lineup. By replacing a belt with a chain and tuning the control software for responsiveness, Subaru aims to balance fuel economy with the brand's characteristic stability and comfort. For most drivers, Lineartronic offers a practical, well-regarded solution in the current Subaru lineup.
Is the Subaru CVT the same as the Toyota?
Like a bicycle but much beefier. Subaru CVTs are manufactured by Subaru and are not the same or even like most other CVTs used in other brands. The TR690 as implemented in the Ascent (and Outback/Legacy XT) requires special handling for things like fluid changes.
What years did Subaru have CVT transmission problems?
While Subaru has improved its CVTs over the years, certain models are more prone to failures: 2010–2013 Subaru Outback & Legacy (First-generation Lineartronic CVT) 2013–2017 Subaru Crosstrek (Early FB20 engine models) 2014–2018 Subaru Forester (FB25 engine models)
What type of CVT does Subaru use?
Subaru Lineartronic® Continuously Variable Transmission (CVT) For instant, seamless response to changing conditions, the redesigned Lineartronic Continuously Variable Transmission elevates efficiency of the BOXER engine and Symmetrical AWD by keeping the engine in its ideal power range.
Has Subaru improved their CVT?
After 2015, Subaru's Lineartronic transmissions got major upgrades — better cooling, tougher clutch packs, and better software. These changes fixed the root causes of early Subaru CVT failures and made them last longer.
