When an Allison 1000/2000 transmission produces a pressure-switch code, it does not necessarily mean the pressure switch is faulty. A solenoid needs to stroke a valve, which then sends oil pressure to the switch to close it. If the solenoid is performing poorly, or the valve is sticking, the pressure switch will not close, causing the associated code to set.
