Service Procedure
NOTE: Most vehicles will improve and no longer exhibit the condition after the first 8,000 km (5,000
mi) of driving.
1. Does the vehicle have more than 8,000 km (5,000 mi) on the odometer?
(1). Yes - overhaul (clean and inspect) the main control valve body. Refer to Workshop Manual (WSM),
Section 307-01. Repair is complete.
(2). No - proceed to Step 2.
2. Are any transmission related DTCs present?
(1). Yes - determine the appropriate clutch(s) to be cycled related to DTCs present. Refer to Workshop
Manual (WSM), Section 307-01.
(2). No - determine the appropriate clutch(s) to be cycled related to symptoms present. Refer to WSM,
Section 307-01.
3. Record and clear all DTCs present before performing the PCM - Transmission Accelerated Main
Control Break In routine.
CAUTION: Failure to use a frame engaging lift could damage the vehicle.
4. Prepare vehicle for PCM - Transmission Accelerated Main Control Break In routine by positioning on a
frame-engaging lift with wheels off the ground to prevent vehicle movement.
5. Using the latest software level of the appropriate Ford diagnostic scan tool, perform the PCM Transmission Accelerated Main Control Break In routine 3 times on the appropriate clutch(s) determined
to be cycled.
6. Perform the adaptive learning drive cycle. Refer to WSM, Section 307-01.
7. Does the vehicle still exhibit the condition after performing the PCM - Transmission Accelerated Main
Control Break In routine and adaptive learning drive cycle?
(1). Yes - overhaul (clean and inspect) the main control valve body. Refer to WSM, Section 307-01.
(2). No - repair is complete.
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.
