Experiencing rough shifting or delayed acceleration in your 2014 Subaru after a transmission service? You’re not alone. Many Subaru owners find themselves needing to perform an A/T (Automatic Transmission) relearn, especially after a fluid change. While a scan tool is the typical solution, you might wonder if there’s a way to do a 2014 Subaru A/T relearn without a scan tool. Let’s explore the possibilities and provide some guidance.
Understanding the 2014 Subaru CVT and A/T Relearn
Subaru’s Continuously Variable Transmission (CVT), used in many 2014 models, relies on sophisticated software to ensure seamless gear changes and optimal performance. This software learns your driving style and adjusts shift points accordingly. However, certain events, like a transmission fluid change or a disconnected battery, can disrupt this learned data, requiring an A/T relearn procedure.
An A/T relearn essentially involves resetting the transmission control module (TCM) and allowing it to re-learn your driving habits. This process helps restore smooth shifting, improve fuel economy, and prevent potential transmission problems down the line.
The Scan Tool Method: The Most Reliable Approach
While the internet offers various DIY methods for a 2014 Subaru A/T relearn without a scan tool, it’s crucial to understand that these methods are not officially endorsed by Subaru and may not work consistently across all models.
Using a scan tool remains the most reliable and recommended method for several reasons:
- Precision: Scan tools communicate directly with the TCM, ensuring an accurate and complete reset.
- Safety: DIY methods often involve manipulating the vehicle’s electrical system or driving in specific ways, which could potentially harm your transmission or other components if not done correctly.
- Time-Saving: A scan tool can perform the relearn quickly and efficiently, while DIY methods often involve lengthy driving procedures.
“Attempting to relearn the transmission without the proper equipment can sometimes lead to more significant issues. It’s best to rely on the tools designed for the job.” – John Miller, Senior Automotive Technician
Exploring Alternatives: Proceed with Caution
If accessing a scan tool isn’t feasible, you might find anecdotes online about methods like disconnecting the battery or driving a specific pattern to trigger a relearn. However, it’s crucial to approach these with extreme caution:
- Lack of Guarantee: There’s no guarantee these methods will work, and they might even vary depending on your specific Subaru model’s software.
- Potential Risks: Incorrectly performing these methods could lead to further transmission problems or even damage other vehicle systems.
“While some DIY methods claim to work, they often lack consistency and pose unnecessary risks. Investing in a professional-grade scan tool or consulting a trusted mechanic is always the safer bet.” – Emily Chen, Automotive Software Engineer
When in Doubt, Consult the Professionals
Ultimately, your 2014 Subaru deserves the best care. When it comes to an A/T relearn, using a scan tool remains the safest, most reliable, and often most efficient solution. If you’re uncomfortable performing the procedure yourself, numerous reputable mechanics and dealerships can assist you.

FAQs
1. How often does my 2014 Subaru need an A/T relearn?
Subaru doesn’t have a set mileage interval. It’s generally recommended after a transmission fluid change, battery disconnect, or if you experience shifting issues.
2. Can I use any scan tool for a 2014 Subaru A/T relearn?
Not all scan tools are created equal. Some basic models may only read codes, while others offer advanced functions like relearns. Check the tool’s specifications or consult the manufacturer to ensure compatibility.
3. What are the symptoms of a transmission needing a relearn?
Common symptoms include rough shifting, delayed engagement, harsh downshifts, and decreased fuel economy.
4. Is it safe to drive my Subaru if it needs an A/T relearn?
While it might be drivable, driving with an uncalibrated transmission could worsen existing issues or lead to more significant problems down the line. It’s best to address the relearn promptly.
5. How long does an A/T relearn take?
Using a scan tool, the procedure itself is relatively quick. However, the relearning process, where the TCM adapts to your driving, can take a few days of regular driving.
