Issue: Some 2020 Explorer/Aviator/Police Interceptor Utility vehicles equipped with a 10R60/10R80
automatic transmission may exhibit a harsh engagement/harsh shift/delayed shift with or without an
illuminated malfunction indicator lamp (MIL) or diagnostic trouble codes (DTCs) P0729, P0731, P0732,
P0733, P0734, P0735, P0736, P076F, P07D9, P07F6, P07F7, P0751, P0756, P0761, P0766, P0771,
P2707, P2700, P2701, P2702, P2703, P2704 and/or P2705 stored in the powertrain control module
(PCM). This may be due to sticking valves in the main control valve body. Most vehicles will improve and
no longer exhibit the condition after the first 8,000 km (5,000 mi) of driving. To correct the condition, follow
the Service Procedure steps to perform the PCM - Transmission Accelerated Main Control Break In
routine for the appropriate clutch(s) and/or replace the main control valve body.
Action: Follow the Service Procedure steps to correct the condition on vehicles that meet all of the
following criteria:
• 2020 Explorer/Aviator/Police Interceptor Utility
• 10R60/10R80 automatic transmission
• At least one of the following symptoms:
- Harsh engagement
- Harsh shift
- Delayed shift
• With or without illuminated MIL and DTCs P0729, P0731, P0732, P0733, P0734, P0735,
P0736, P076F, P07D9, P07F6, P07F7, P0751, P0756, P0761, P0766, P0771, P2707,
P2700, P2701, P2702, P2703, P2704 and/or P2705 stored in the PCM

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 - replace the main control valve body. Refer to Workshop Manual (WSM), Section 307-01.
Repair is complete.

(1). Yes - determine the appropriate clutch(s) to be cycled related to DTCs present. Refer to WSM,
Section 307-01.
(2). No - proceed to Step 4 to cycle all 6 clutches.
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 the vehicle for PCM - Transmission Accelerated Main Control Break In routine by positioning
the vehicle on a frame-engaging lift with the 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 - replace the main control valve body. Refer to 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.
(2). No - repair is complete.
