Shift Quality Quick-Learn Procedure: Notes
This procedure quickly optimizes shift quality. Procedure must be performed after disconnecting battery or loss of voltage supply to Transmission Control Module (TCM), replacing TCM, transmission internal components, solenoid assembly or torque converter. Chrysler's Diagnostic Readout Box (DRB) scan tool with proper cartridge must be used to perform shift quality quick-learn procedure.
The following conditions must be met when performing shift quality quick-learn procedure: oil temperature must be greater than 60°F (16°C), brakes must be applied when indicated, engine speed greater than 500 RPM, throttle angle less than 3 degrees, gearshift lever must be moved only when indicated, gearshift lever must remain in overdrive as indicated until DRB indicates procedure is completed.
If unused replacement TCM is installed on vehicle with engine at normal operating temperature, shift quality quick-learn procedure will cause TCM to indicate a cold oil temperature. Oil temperature must be monitored with DRB. If oil temperature is less than 60°F (16°C), allow engine to idle until oil temperature is greater than 60°F (16°C). If oil temperature is greater than 200°F (94°C), allow transmission to cool until oil temperature is less than 200°F (94°C).
