TECHNICAL SERVICE BULLETIN
10R140 Automatic Transmission – Harsh Engagement/Harsh
Shift/Delayed Shift With Or Without DTCs
03
December
2020
Model:
Ford
2020 F-Super Duty
Transmission/Transaxle: (10R140)
Issue: Some 2020 F-Super Duty vehicles equipped with a 10R140 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) or transmission control module (TCM). 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 transmission accelerated main control break-in routine for the
appropriate clutch(es) 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 F-Super Duty
• 10R140 automatic transmission
• At least one of the following conditions:
- Harsh engagement
- Harsh shift
- Delayed shift
• With or without 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 or TCM

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.
