TRANSMISSION AR-POWER SHIFT 1424436 - Caterpillar

Probable Causes
The probable root causes are listed in order below:
Air inlet system or exhaust system
Valve lash
Electronic unit injectors
Boost pressure sensor
Atmospheric pressure sensor
Electronic system problem
Personality moduleRecommended Actions
Perform the following diagnostic procedures in order:
Check the air inlet system for restrictions or leakage. Check the exhaust system for restrictions or leakage. Refer to Systems Operation/Testing and Adjusting, "Air Inlet and Exhaust System - Inspect".
Check the engine's valve lash. Refer to Systems Operation/Testing and Adjusting, "Engine Valve Lash - Inspect/Adjust".
Check electronic unit injectors.
Ensure that the valve cover connectors for the unit injectors are fully connected and ensure that the valve cover connectors are free of corrosion.
Ensure that the J2/P2 connectors for the Engine Control Module (ECM) are fully connected and ensure that the ECM connectors are free of corrosion.
Connect Caterpillar Electronic Technician (ET) to the service tool connector. Perform the "Cylinder Cutout Test". Access the "Cylinder Cutout Test" by selecting the "Diagnostic Tests" under the "Diagnostics" menu. Run the "Cylinder Cutout Test" in order to disable each cylinder. Disabling each cylinder allows the technician to isolate the misfiring cylinders. If the misfiring cylinder can be isolated to a specific cylinder, refer to Troubleshooting, "Injector Solenoid Circuit - Test".
Check the boost pressure sensor and the atmospheric pressure sensor for correct operation.
While the problem is occurring, check for diagnostic codes that are related to the boost pressure sensor and the atmospheric pressure sensor. If there is an active diagnostic code for a pressure sensor, refer to Troubleshooting, "Engine Pressure Sensor Open or Short Circuit - Test".
Check for an electronic system problem.
Monitor the fuel position, the Rated Fuel Limit and the FRC Fuel Limit. While the vehicle is operating under full load, the parameters should meet the following conditions:
The fuel position is equal to the Rated Fuel Limit.
The fuel position is less than the FRC Fuel Limit.If the fuel position is equal to the Rated Fuel Limit and the fuel position is less than the FRC Fuel Limit, the Electronics are operating correctly. Go to Step 7.
If the fuel position is not equal to the Rated Fuel Limit and/or the fuel position is not less than the FRC Fuel Limit, perform the following tests in order:
Without starting the engine, turn the keyswitch to the ON position. Check the parameter for the boost pressure on the status screen. When the engine is off, the boost pressure should be 0 kPa (0 psi).
Monitor the status for "Accelerator Pedal Position Sensor". Fully depress the accelerator pedal and release the accelerator pedal. The status should be 0% at low idle and 100% at high idle. If the status does not reach 0% or 100%, check the duty cycle of the accelerator pedal position sensor. Select "Monitor Throttle Position Sensor" from the "Calibrations" under the "Service" menu on Cat ET in order to monitor the duty cycle of the accelerator pedal position sensor. Fully depress the accelerator pedal and release the accelerator pedal. The accelerator pedal position sensor is within calibration when both of the following conditions are met:
