Inside the Eaton UltraShift service manual
- General information, warnings and transmission overview
- Electronic Clutch Actuator (ECA) service
- X-Y electric shifter and shift control
- Medium- and heavy-duty TECU replacement
- Output, main and input shaft speed sensors
- Rail and gear select sensors
- Appendix: lubrication specifications and intervals
The manual is organised as component-level service work rather than diagnostics. General information covers warnings, a transmission overview, serial-tag and model nomenclature, and clutch greasing guidelines including the grease-interval reset through ServiceRanger. Service procedures then walk through the thread-in ECA speed sensor, the Electronic Clutch Actuator, the inertia brakes, the X-Y electric shifter and shift control, the medium- and heavy-duty transmission harnesses and TECU units, and the full family of speed sensors and rail and gear select sensors. Real torque figures appear throughout, such as 35 to 45 lb-ft on the ECA mounting flange and 34 to 45 lb-ft on cast-iron shifter housings. The appendix adds inspection procedures, lubrication specifications, wet-clutch level checks and change intervals, and directs the reader to Roadranger-approved lubricant publication TCMT0020.
Applicable truck models
Models covered include RTO, RTLO, FO and FOM series such as RTO-16910B-DM3, RTLO-18918A-AS3 and FO-16E318B-MXP, plus DM3, AS3, AW3 and PV variants listed on the model page. Torque values such as 35–45 lb-ft on the ECA mounting flange are specified throughout. Verify coverage against your VIN and build sheet on the Eaton Roadranger site.
