The Autel AL319 is a popular entry-level OBD2 scanner known for its affordability. But can it read transmission codes? This article explores the AL319’s capabilities, compares it to other scanners, and answers your questions about diagnosing transmission issues.
While the Autel AL319 excels at reading basic engine codes, it does not typically read transmission codes. Transmission codes often require a more advanced scanner capable of communicating with the Transmission Control Module (TCM). The AL319 primarily focuses on engine diagnostics and may not have the necessary protocols to access the TCM.

Why Can’t the AL319 Read Transmission Codes?
The inability to read transmission codes stems from the AL319’s design and intended use as a basic OBD2 scanner. It’s primarily designed for retrieving generic powertrain (P0XXX), chassis (C0XXX), and body (B0XXX) codes related to emissions and basic vehicle functions. Transmission systems often utilize manufacturer-specific codes and require specialized communication protocols that the AL319 lacks.
(The OBD2 port allows scanners to communicate with various vehicle modules, but access depends on the scanner’s capabilities.)
Comparing the AL319 to Other Autel Scanners
Higher-end Autel scanners, such as the MaxiDiag series (e.g., MD808, MK808) and the MaxiSys series (e.g., MS906, MS908), do offer transmission code reading capabilities. These professional-grade tools have broader vehicle coverage, support more communication protocols, and can access manufacturer-specific data, including transmission codes.
Finding the Right Scanner for Transmission Diagnostics
If you need to read transmission codes, consider investing in a more advanced scanner. Features to look for include:
- Transmission Code Reading: Ensure the scanner explicitly states its ability to read transmission codes.
- Manufacturer-Specific Coverage: Check compatibility with your vehicle’s make and model to ensure access to all necessary data.
- Live Data Streaming: This allows you to monitor transmission parameters in real-time for more in-depth diagnostics.
- Bi-Directional Control: While not essential for code reading, this feature enables performing tests on transmission components.
(Advanced scanners like the Autel MaxiSys MS906BT offer comprehensive diagnostics, including transmission code reading.)
Conclusion
While the Autel AL319 provides excellent value for basic OBD2 diagnostics, it falls short when it comes to reading transmission codes. For comprehensive transmission diagnostics, consider upgrading to a more advanced Autel scanner or a similar professional-grade tool designed for in-depth vehicle analysis. Investing in the right tool ensures accurate diagnosis and efficient repairs.
