Diagnosis & fix steps

ACTION: Test terminating resistance across CAN High and Low pins at the transmission pass-through connector (spec: 60Ω total). Inspect twisted-pair wiring near the starter motor for heat burn.
Red Seal field insights
Drivetrain Network: Automated shifts require instantaneous engine torque reduction requests; if the TCM cannot broadcast torque-limit packets over CAN, it holds the clutch open in neutral.
