18.CHECK FOR INTERMITTENT OPERATION
The conditions to set this DTC are not currently present.
With the scan tool, check the DTC EVENT DATA to help identify the conditionsin which the DTC was set.
If the DTC Event Data shows fault P0733 was set in the Park, Reverse, or Neutral, replace the Powertrain
Control Module.
If the DTC Event Data shows fault P0733 set with input RPM = zero, check the input speed sensor and related
wiring.
If the DTC Event Data shows fault P0733 set with line pressure significantly below desired line pressure, check
for the cause of low line pressure (i.e., oil level, misinstalled or damaged primary filter or filter seal, sticking
main regulator valve in pump, etc.).
If the DTC Event Data shows fault P0733 set with the OD or UD pressure switch open (but line pressure
matches Desired Line Pressure), air check the OD and UD hydraulic clutch circuits for leakage per the Service
Information. If the OD and UD hydraulic clutch circuits are OK, replace theTransmission Solenoid/TRS assem-
bly.
Check the gearshift linkage adjustment.
Intermittent Gear Ratio DTCs can be set by problems in the Input and Output Speed Sensor circuits and/or Speed
Sensor Ground circuit.
Remove the Ignition Switch Feed fuse from the TIPM.
CAUTION: Removal of the Ignition Switch Feed fuse from the TIPM will prevent the vehicle from being
startedingear.
WARNING: The Ignition Switch Feed fuse must be removed from the TIPM. Failure to do so can result in
personal injury or death.
Install the Transmission Simulator, Miller tool #8333.
Wiggle wiring and connectors while checking for intermittent operation with the Transmission Simulator.
Gear ratio DTCs can also be set under extreme temperature conditions.
Verify if the problem is only experienced under extreme hot or cold conditions.
Were there any problems found.
