P075B — Shift Solenoid G Performance/Stuck Off
Shift solenoid G is electrically intact, but its hydraulic effect is missing — when commanded on, the gear it should engage does not lock up. Either the solenoid is mechanically stuck closed, the valve body bore is worn, or hydraulic pressure does not reach the clutch pack.
General code reference. Confirm the definition and diagnostic procedure for your vehicle's year, model and engine. A stored code alone does not identify a failed part.
