Does Subaru use Jatco transmissions?

No, Subaru does not use Jatco transmissions in its vehicles. Subaru has its own in-house developed transmission technology that it utilizes across its lineup of all-wheel-drive vehicles.

Subaru's Transmission Technology

Subaru is known for its Symmetrical All-Wheel Drive (AWD) system, which is a core part of the brand's engineering philosophy. To power this AWD system, Subaru has developed its own proprietary transmission technology over the years. Subaru's transmissions are designed and manufactured in-house, rather than sourcing them from third-party suppliers like Jatco.

The main transmissions used in Subaru vehicles include:

Lineartronic Continuously Variable Transmission (CVT)

6-speed Manual Transmission

5-speed Manual Transmission

Subaru's Lineartronic CVT is a key component of its modern powertrain lineup, providing smooth and efficient power delivery to the AWD system. The manual transmissions are also engineered to work seamlessly with Subaru's AWD architecture.

Why Subaru Develops Its Own Transmissions

Subaru's decision to develop its own transmissions, rather than using off-the-shelf units from suppliers like Jatco, is driven by a few key factors:

Optimized for AWD: Subaru's transmissions are specifically designed to integrate with its Symmetrical AWD system for maximum efficiency and performance.

Reliability and Durability: By controlling the entire powertrain development process, Subaru can ensure its transmissions meet high standards for reliability and longevity.

Brand Identity: Subaru's in-house transmission technology is a core part of the brand's engineering identity and reputation for capable, all-weather vehicles.

So in summary, while Jatco is a major supplier of transmissions to many automakers, Subaru has chosen to develop its own proprietary transmission technology to best suit the needs of its Symmetrical AWD system and brand identity.

Is Subaru still using CVT transmissions?

Yes, Subaru continues to use continuously variable transmissions (CVTs) in many of its models, like the Outback, Forester, Impreza, and Crosstrek, as they are a standard feature for most automatic transmissions since the 2014 model year. However, some models, like the Subaru BRZ, still come with traditional manual or automatic transmissions.

Mainstream Models: Subaru uses its Lineartronic CVT in popular models to improve fuel efficiency and provide a smooth driving experience without traditional gear shifts.
Exception: The Subaru BRZ is the exception, as it is offered with a traditional manual or automatic transmission instead of a CVT.
Performance: Some performance models, like the WRX, feature a high-torque Lineartronic CVT that can be manually controlled with paddle shifters.
Reliability and Maintenance: While newer CVTs have improved, earlier models (2010–2017) had some reliability concerns, leading Subaru to offer an extended warranty for many of those vehicles. Regular maintenance is crucial to ensure longevity.

What is the best transmission for a Subaru?

The "best" Subaru transmission depends on your priorities, as Subaru's Lineartronic CVT is highly efficient and smooth for most drivers, especially in 2017 and newer models, while the 6-speed STI manual transmission is the best for performance enthusiasts. For older models, the pre-CVT 4-speed automatic is considered robust by some, but has limitations compared to modern options.

For efficiency and everyday driving

Lineartronic CVT (2017-present): Considered the best all-around for modern Subarus. It offers excellent fuel economy and smooth, linear acceleration.
Improvements since 2015: Upgrades like external coolers, improved clutch packs, and refined software have addressed early CVT issues. For a positive experience, maintain proper service intervals and avoid excessive strain.
Manual mode: All Lineartronic CVTs come with a manual mode that simulates a 6-speed with paddle shifters for a sportier feel when needed.

For performance and enthusiast driving

6-speed STI manual: This is the top choice for performance and durability, designed with motorsport in mind. It is significantly stronger and has higher operability than previous 5-speed versions.
Best for swaps: The 2007 STI 6-speed is often favored for its compatibility with earlier WRX models and its use of a speed sensor and a compatible final drive ratio, notes a YouTube video.

For older models

Pre-CVT 4-speed automatic: For those who prefer a traditional automatic, some drivers consider the older 4-speed automatic (found in models from 2008-2013) to be more robust and easier to maintain than the early CVTs.
Manual option: Some older models came with 5-speed manual transmissions, which are generally reliable, though they may lack refinement compared to modern options.

Do subarus use Jatco transmissions?

All of Subaru's three speed automatic transmissions were made by Jatco.

What car manufacturers use Jatco transmissions?

And by other automakers. Including Suzuki and Renault while Jatco also makes a DC converter. Case for the Nissan Leap tech upgrades are frequent with the EVVT8.
