ISSUE
Some vehicles equipped with a 3.0L engine and 5R44E transmission may exhibit a flashing Transmission Control Indicator Lamp (TCIL) and/or a delayed 1-3 shift with Diagnostic Trouble Code (DTC) P0733. This DTC may be set when cold below 4 °C (40°F) and during light throttle accelerations after start up. This may be caused by the calibration of the Powertrain Control Module (PCM).
ACTION
Follow normal diagnostic procedures and verify condition. Repair all non-related DTCs. If the condition is valid, reprogram the PCM to the latest calibration level. Refer to the following Service Procedures for details.
SERVICE PROCEDURE
Follow normal diagnostic procedures and verify the condition.
1. If the condition is valid, first repair all DTCs that may be present.
2. Determine if the condition is caused by an internal transmission component and repair as required.
3. Clear all DTCs and validate the repair.
4. If the condition is still present or returns after repair, the PCM must be reprogrammed. Refer to the PCM Calibration Information Chart shown.
5. Follow the procedures found in the Powertrain Control/Emissions Diagnosis (PC/ED) Workshop Manual and reprogram the PCM to latest calibration level.
6. Verify PCM reprogramming has corrected the condition.
NOTE
AN ADAPTIVE LEARNING STRATEGY IN THE PCM CONTROLS THE SHIFT FEEL AND TIMING ON THE TRANSMISSION. THIS FEATURE IS DESIGNED TO INCREASE DURABILITY AND PROVIDE CONSISTENT SHIFT FEEL OVER THE LIFE OF THE VEHICLE. AS A RESULT OF THIS REPROGRAMMING, THE TRANSMISSION MAY HAVE FIRM AND/OR SOFT SHIFTS. THIS OPERATION IS CONSIDERED NORMAL AND WILL NOT AFFECT FUNCTION OR DURABILITY OF THE TRANSMISSION. ONCE THE VEHICLE IS AT OPERATING TEMPERATURE, IT MAY TAKE SEVERAL SHIFTS AT THE SAME OPERATING CONDITION FOR THE TRANSMISSION TO PROPERLY ADAPT. OVER TIME, THE ADAPTIVE LEARNING PROCESS WILL FULLY UPDATE TRANSMISSION OPERATION. THE MORE VARIED THE DRIVING HABITS, SPEED AND TORQUE, THE LONGER IT MAY TAKE TO ADAPT, BUT THE MORE COMPLETE THE PROCESS WILL BE. ADDITIONALLY, THE RESETTING OF KEEP ALIVE MEMORY (KAM) SUCH AS PCM DISCONNECT, BATTERY DISCONNECT OR INSTALLATION OF A NEW BATTERY, THE STRATEGY MUST RELEARN.
Obtain an Authorized Modifications Decal (FPS 8262 - obtainable through DOES II, 25/pkg) and list the date, dealer number, and summary of modifications performed. Select a prominent place adjacent to the Vehicle Emission Control Information Decal suitable for installing the Authorized Modifications Decal. Clean the area, install the decal, and cover it with a clear plastic decal shield.
