Eaton Automated Manual Transmissions (AMTs) do not default to mechanical operation in the event of a loss of chassis electricity; they require electrical power to operate the shift actuation and clutch control. If the electrical power is lost, the transmission cannot shift automatically. Technician B's statement is also incorrect because the output shaft rotation depends on the transmission being in gear and the clutch being engaged; if the transmission is in neutral or the clutch is disengaged, the output shaft may not rotate even if the engine is running.
