Service Instruction
1. Reprogram the PCM using the latest software level of the appropriate Ford diagnostic scan tool.
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.
