Subaru Transmission Solutions: Test, Don't Guess

Utah County’s Independent Authority for CVT, Automatic, & Manual Transmissions.

Have you been told you need a new transmission? Get a Second Opinion,.  Dealers and general shops often view the Subaru CVT (Continuously Variable Transmission) as a disposable unit. If it acts up, they quote you $7,000+ to replace it.

At JFM Auto, we dig deeper. We don't just pull codes; we perform a comprehensive Testing and Evaluation. We specialize in identifying the root cause—whether it’s a failing valve body, a solenoid issue, or simple fluid degradation. We often repair transmissions that others condemn, saving our customers thousands.

The #1 Killer of Subaru CVTs: Heat & Neglect

Most transmission failures we see in Utah County are preventable. Subaru CVTs run hot, especially when climbing our canyons or towing. Over time, this heat breaks down the fluid, leading to "shuddering," hesitation, and eventual failure.

Our Preventative Approach (Save Your Transmission):

• CVT Fluid Exchange & Relearn: We don't just "drain and fill." We use factory-level equipment to exchange the fluid and—crucially—perform the Transmission Relearn Procedure to recalibrate your vehicle's computer.
• BG High-Performance CVT Fluid: We go beyond the factory standard. We use BG CVT fluid, which outperforms the original fluid and helps restore smooth operation to worn transmissions.

Don't wait for the warning light. If you are over 30,000 miles, schedule a fluid evaluation today.

Recognizing the Warning Signs

If your Subaru is doing any of the following, it is trying to tell you something. We speak the language.

• The Flashing "AT OIL TEMP" Light: This is the most common sign of a transmission fault. It doesn't always mean "dead transmission"—it often points to a solenoid or fluid pressure issue we can solve.
• The "Christmas Tree" Dash: When a Subaru detects a fault, it lights up everything: Check Engine Light (solid), Cruise Control (flashing), and EyeSight/X-Mode (disabled). This "limp mode" is designed to protect your car.
• Shuddering or "Jerking": If your car vibrates or shudders when accelerating (often between 15–30 mph), your CVT chain or torque converter may be struggling with old fluid.
• Delayed Engagement: If there is a long pause when you shift from Park to Drive, your fluid pressure may be low.

Do not wait Give us a call today if you are experiencing any of these symptoms 

General mechanics often guess. We test. Our process includes:

• Solenoid & Valve Body Testing: We verify if specific components can be replaced without removing the transmission.
• Fluid Condition Analysis: We check for burnt fluid or metal debris to determine the health of your internal components.
• Drivability Logic Testing: We evaluate if the issue is mechanical or a software calibration error.
