Description
Eaton Gen III Automated Transmissions Troubleshooting Guide
The Eaton Gen III Automated Transmissions Troubleshooting Guide TRTS0930 EN-US is a detailed diagnostic and troubleshooting reference designed for Eaton automated transmission systems. The manual covers UltraShiftĀ® and AutoShiftĀ® applications and provides structured procedures for identifying electrical, electronic, transmission, clutch, communication, sensor, actuator, and shifting-related problems.
The guide begins with general diagnostic information, safety warnings, transmission model identification, diagnostic procedures, and fault-code retrieval and clearing procedures. It explains both manual fault-code retrieval and the use of ServiceRanger for accessing and clearing diagnostic information.

Comprehensive Fault-Code Diagnostics
A major section of the manual is dedicated to Fault Code Isolation Procedures. The guide provides diagnostic information for numerous Eaton transmission fault codes, including ECU operation, ECU configuration, J1939 communication, shift-control devices, clutch operation, battery voltage, solenoid valves, speed sensors, rail and gear position sensors, select motors, ECA systems, grade sensors, and gear engagement problems.
The fault-code index associates codes with diagnostic identifiers such as SPN, PID, SID and FMI, allowing technicians to quickly locate the appropriate isolation procedure. Examples covered in the guide include Fault Codes 11, 12, 13, 14, 15, 16, 17, 18, 19, 21, 22, 26, 27, 28, 29, 31ā37, 41ā46, 51, 52, 56ā58, 61, 63ā68, 71ā75, 81, 83ā85 and 99.
Electrical Pretests and Power Diagnostics
The manual contains extensive electrical pretest procedures intended to verify the basic electrical condition of the transmission system before performing individual fault-code isolation procedures. These sections cover battery condition, starter and battery connections, TECU power supply, ECA power supply, wiring harnesses, fuses, connectors and electrical connections.
The sample also includes detailed diagrams for the TECU Power Harness and Heavy-Duty Electric Clutch Actuator (ECA) Power Harness. The guide specifies the relevant fuse arrangements and provides diagrams for preferred 12-volt battery connection configurations.
Diagnostic Procedures
The diagnostic workflow helps technicians move systematically from the transmission gear display and engine-starting condition through gear engagement, active and inactive fault-code checks, road testing, and fault-code duplication. This symptom-driven approach can help reduce unnecessary component replacement and make troubleshooting more systematic.
Product Diagnostic (PD) Mode
The guide also explains Product Diagnostic (PD) Mode, which is intended to help diagnose intermittent or inactive faults. The procedure increases fault-sensing sensitivity and can help technicians identify loose, degraded, or intermittent wiring and connector problems. The manual provides instructions for entering and exiting PD Mode and identifies the inactive fault codes that can be investigated using this procedure.
Symptom-Driven Troubleshooting
A dedicated symptom-driven diagnostics index connects common transmission complaints with the appropriate diagnostic test. Examples include inability to shift using the Up/Down button, engine-starting complaints, loss of J1587 communication, gear-display problems, inability to engage a gear from neutral, shift complaints, clutch engagement problems, and shift-lever backlight problems.
Wiring Diagrams and Connector Information
The guide contains extensive electrical reference information, including connector pin descriptions and wiring diagrams for multiple Eaton transmission configurations. The table of contents identifies diagrams for UltraShift DM3, UltraShift AW3, AutoShift and UltraShift configurations, including 6-speed, 10-speed, 13-speed and 18-speed applications, as well as different shifter configurations.
Transmission Coverage
The manual covers a broad range of Eaton Gen III automated transmission models, including heavy-duty and medium-duty applications. The transmission model list includes models from the F, FM, FO, FOM, RTLO, RTLOM, RTO and RTOM families, covering various UltraShiftĀ® and AutoShiftĀ® configurations.
Useful for Professional Troubleshooting
With its combination of diagnostic flow procedures, fault-code isolation information, electrical testing, wiring diagrams, connector descriptions and symptom-based troubleshooting, this manual is a useful reference for technicians working on Eaton automated transmissions.
Digital PDF format makes the manual convenient for workshop, field-service and maintenance reference. The supplied product contains 400 pages and has a file size of approximately 32 MB.
