Summary

This article supersedes TSB 22-2139 to update vehicle model years affected.

Issue: Some 2017-2020 F-150, 2018-2021 Expedition/Navigator/Mustang and 2019-2023 Ranger vehicles equipped with a 10R80 automatic transmission may exhibit a harsh engagement/harsh shift/delayed shift. It is possible the vehicle may also have an illuminated malfunction indicator lamp (MIL) or diagnostic trouble codes (DTC) P0751, P0752, P0756, P0757, P0761, P0762, P0766, P0767, P0771, P0772, P2700, P2701, P2702, P2703, P2704, P2705, P2707, P2708, P0729, P0731, P0732, P0733, P0734, P0735, P0736, P076F, P07D9, P07F6 and/or P07F7 stored in the powertrain control module (PCM) or transmission control module (TCM). This may be due to incompatibility of the adaptive calibration to adapt to hardware break-in over time. To correct the condition, follow the Service Procedure steps to overhaul the main control valve body and/or perform an adaptive learning drive cycle.

Action: Follow the Service Procedure to correct the condition on vehicles that meet all of the following criteria:

• One of the following vehicles:

- 2017-2020 F-150

- 2018-2021 Expedition/Navigator/Mustang

- 2019-2023 Ranger

• 10R80 automatic transmission

• At least one of the following symptoms:

- Harsh engagement

- Harsh shift

- Delayed shift

Parts

Quantity refers to the amount of the service part number required to repair the vehicle.

Unit of Issue refers to the number of individual pieces included in a service part number package.

Piece Quantity refers to the total number of individual pieces required to repair the vehicle.

As Needed indicates the amount of the part may vary and/or is not a whole number. Parts can be billed out as non-whole numbers, including less than 1.

Parts - Parts To Inspect And Replace Only If Necessary

If Needed indicates the part is not mandatory.

Warranty Status: Eligible under provisions of New Vehicle Limited Warranty (NVLW)/Emissions Warranty/Service Part Warranty (SPW)/Service Part New Vehicle (SPNV)/Extended Service Plan (ESP) coverage.

Service Procedure

1. Are any of the following DTCs present: P0751, P0752, P0756, P0757, P0761, P0762, P0766, P0767, P0771, P0772, P2700, P2701, P2702, P2703, P2704, P2705, P2707, P2708, P0729, P0731, P0732, P0733, P0734, P0735, P0736, P076F, P07D9, P07F6 and/or P07F7?

(1). Yes - proceed to Step 4.

(2). No - proceed to Step 2.

2. Reprogram the transmission strategy download into the PCM/TCM. Perform the adaptive learning drive cycle. Refer to Workshop Manual (WSM), Section 307-01.

3. Does the vehicle still exhibit the condition after performing the transmission strategy download and adaptive learning drive cycle?

(1). Yes - proceed to Step 4.

(2). No - repair is complete.

4. Overhaul the main control valve body and road test vehicle following the adaptive learning drive cycle. Refer to WSM, Section 307-01.

(1). Upon removal of the transmission fluid pan, metal flakes may be present on the magnet. This is a normal condition. (Figure 1)

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.
