Service Procedure

1. Replace the main control valve body assembly. Refer to Workshop Manual (WSM), Section 307-01.

NOTE: Advise the customer 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.
