Eaton Gen 1 (AutoShift) Fault Code: 42 PID: SID 61 FMI: 7 Splitter Failed To Engage

Overview:
This code indicates the transmission is unable to complete a shift across the splitter. The splitter is either stuck in HI or LO, or cannot complete engagement in HI or LO.

Detection:
The transmission attempts the same splitter shift five consecutive times and determines the shift cannot be completed based on the speeds across the back box.

Fallback:
This fault causes a 9-speed fallback and the transmission stays in either LO split or HI split.

Required Tools:
1) Basic Hand Tools
2) (2) 0-100 PSI Air Pressure Gauges
3) AutoSelect/AutoShift Troubleshooting Guide

Possible Causes:
1) Low air pressure
2) Contaminated air supply
3) Air leak
4) Splitter solenoid stuck
5) Failed splitter actuator/cylinder/piston/yoke
