Service Procedure

1. Reprogram the PCM and TCM using the latest software level of the Ford Diagnosis and Repair System (FDRS) diagnostic scan tool.

2. Using the FDRS Reset/Clear Specified Function application, perform the Reset Minimum Fuel Mass Adaptions All Cylinders.

NOTE: Advise the customer that this vehicle is equipped with an adaptive transmission shift strategy which allows the vehicle's computer to learn the transmission's unique parameters and improve shift quality. When the adaptive strategy is reset, the computer will begin a relearning process. This relearning process may result in firmer than normal upshifts and downshifts for several days.
