# Service bulletin TSB 23\-2123

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10234596
- Published by NHTSA: 2023\-05\-04
- Manufacturer's number: TSB 23\-2123
- Manufacturer's date: 2023\-04\-14
- NHTSA component: ELECTRICAL SYSTEM; POWER TRAIN

## NHTSA's summary

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.

- [SSM 55037](/bulletins/11035233.md), 2026-07-27, Service bulletin: UNKNOWN OR OTHER; ELECTRICAL SYSTEM; SEATS. Some 2018\-2024 Expedition and 2018\-2027 Navigator vehicles equipped with a rear seat entertainment system/Lincoln Play may experience various system concerns. Rear seat entertainment systems are not on a controller area network \(CAN\) and are not supported by the Ford Diagnostic and Repair System \(FDRS\). Certain system concerns may be resolved through software updates which will automatically download once each individual monitor is connected to Wi\-Fi. Diagnostic support for rear seat entertainment systems is provided by VOXX electronics. If necessary, contact the VOXX Customer Service Department at 1\-866\-869\-7888. If possible, record the device serial number by selecting the gear/Setup icon \> Settings \> Device and Software \> About. If the unit will not power up, the serial number is on a label on the back of the monitor. It is helpful to know the date the issue occurred, how long the monitors were on prior to the issue, what app/input/media was being used, and if the system software was recently updated prior to the concern starting.
