Some vehicles equipped with the 4.2L engine, 4R70W transmission and 3.31 or 3.55 axle ratio may exhibit an intermittent harsh 1-2 shift during light throttle or parking lot maneuvers. This may be caused by the calibration of the Powertrain Control Module (PCM).
Verify condition. If normal diagnostics cannot pinpoint the condition, reprogram the PCM to the latest level calibration. Refer to the following Service Procedure for details.
Follow normal diagnostic procedures and verify the condition.
- If the condition is valid, first service all Diagnostic Trouble Codes (DTC’s) that may be present.
- Determine if the condition is caused by a internal transmission component and repair as required.
- Clear all DTC’s and validate the repair.
- Reprogram the PCM as necessary. Refer to the following PCM calibration chart.
- Follow the procedures found in the Powertrain Control/ Emission Diagnosis (PC/ED) Workshop Manual to reprogram the PCM.

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.
