Shift Quality Quick-Learn Procedure: Notes

This procedure quickly optimizes shift quality. Procedure must be performed if the following conditions have occurred: after disconnecting battery, loss of voltage supply to PCM, PCM replacement, transaxle internal component replacement, solenoid assembly replacement, or torque converter replacement. Chrysler's Diagnostic Readout Box (DRB-III) scan tool with proper cartridge must be used to perform shift quality quick-learn procedure.

If unused replacement PCM is installed on vehicle with engine at normal operating temperature, shift quality quick-learn procedure will cause PCM to indicate a cold fluid temperature. Fluid temperature must be monitored with DRB-III. If fluid temperature is less than 60°F (16°C), allow engine to idle until fluid temperature is greater than 60°F (16°C). If fluid temperature is greater than 200°F (94°C), allow transaxle to cool until fluid temperature is less than 200°F (94°C).

It is imperative that vehicle be shifted into OD with engine running and ensure fluid level is correct. This will purge air in clutch circuits to prevent erroneous clutch volume values, which could cause poor initial shift quality.

The following conditions must be met when performing shift quality quick-learn procedure: fluid temperature must be 60-200°F (16-94°C), brakes must be applied when indicated, engine speed greater than 500 RPM, throttle angle less than 3 degrees, gearshift lever must be in Neutral and moved only when indicated, gearshift lever must remain in overdrive as indicated until DRB-III indicates procedure is completed.
