Machine Stuck in Low Speed / High Range Dead

Diagnosis & fix steps

LOGIC: Two-Speed Travel Shift Solenoid Circuit Voltage High / Open. ACTION: Disconnect 2-speed travel shift solenoid on drive control manifold. Measure coil resistance (~24Ω); trace wiring running back into the center chassis tub for abrasion against steel hydraulic hardlines.

Red Seal field insights

Hardline Rub-Through: High-pressure hydraulic pulses shake adjacent chassis hardlines, cutting through the plastic conduit of the 2-speed shift harness tucked alongside them.
