Allison DOC: Overview, Compatibility, and Connection Requirements

What is Allison DOC?

Allison DOC (Diagnostic Optimized Connection) is official diagnostic software for Allison automatic transmissions used in commercial trucks, buses, construction equipment, military vehicles, and industrial applications.

It provides dealer-level diagnostics, troubleshooting, and programming capabilities for Allison Transmission Electronic Control Units (ECUs). Unlike general truck diagnostic tools, Allison DOC is specifically designed to communicate with Allison transmission controllers.

What Does Allison DOC Do?

• Read & Clear Transmission Fault Codes
• Diagnose active and stored transmission-related trouble codes.
• Live Data Monitoring
• View real-time shift points, torque converter status, clutch pressures, and fluid temperature.
• Transmission Calibration & Programming
• Adjust shift points, torque limits, PTO settings, and adaptive shift learning.
• Transmission Fluid & Clutch Health Monitoring
• Check fluid life, clutch wear indicators, and transmission health.
• Perform Transmission Relearn (Adaptive Shift Learning Reset)
• Helps transmission re-learn driving patterns.
• ECU Software Updates (TCM Flashing)
•  Install the latest calibration files for improved shifting and performance.
• Control Solenoid & Actuator Testing
• Verify functionality of solenoids, valves, and sensors.
• Enable & Adjust PTO (Power Take-Off) Settings
• Modify PTO engagement and operation speed.
