# Service bulletin SSM 50103

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: 10201586
- Published by NHTSA: 2021\-09\-28
- Manufacturer's number: SSM 50103
- Manufacturer's date: 2021\-09\-10
- NHTSA component: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\); ENGINE AND ENGINE COOLING

## NHTSA's summary

Some 2020 Mustang vehicles equipped with a 5.0L engine built on 01\-Sep\-2020 and through 01\-Dec\-2020 may experience an illuminated malfunction indicator lamp \(MIL\) with diagnostic trouble code \(DTC\) P0369 in the powertrain control module \(PCM\). This may be due to a flatness concern on the mega cap on the right hand cylinder head. To correct the condition, replace the right\-hand cylinder head. Refer to Workshop Manual \(WSM\), Section 303\-01B \> Removal and installation \> Cylinder Head RH. For claiming, use causal part 6049 and applicable labor times in Section 06 of the Service Labor Time Standards \(SLTS\) Manual.

## Other bulletins for the same vehicles and component

- [TSB 23\-2350](/bulletins/10245418.md), 2023-11-22, Service bulletin: POWER TRAIN; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\); POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE:SOFTWARE. Some 2017\-2020 F\-150, 2018\-2021 Expedition/Navigator/Mustang, 2019\-2023 Ranger vehicles equipped with a 10R80 transmission may exhibit a harsh/delayed engagement and/or harsh/delayed shift, an illuminated malfunction indicator lamp \(MIL\) with diagnostic trouble codes This may be due to the software in the powertrain control module \(PCM\) or transmission control module \(TCM\), the transmission solenoid ID strategy, sticking valves in the main control valve body and/or axial movement of the CDF clutch cylinder \(7H351\) sleeve. To correct the condition, follow the Service Procedure to identify and correct the condition.
- [SSM 51232](/bulletins/10228848.md), 2023-01-05, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION. Some 2018\-2022 Mustang vehicles equipped with a 5.0L engine and a 10R80 transmission may exhibit a buck/jerk sensation that may be perceived as an engine misfire during throttle tip\-in between 35\-45 MPH \(56\-72 KPH\) and with the transmission in 8th, 9th, or 10th gear. This buck/jerk sensation can be compared to a like vehicle that is equipped with a similar powertrain \(engine, transmission, and rear end gear ratio\) and driven in the same manner. A diagnostic trouble code \(DTC\) will not set because of this condition. If a misfire DTC is present, the DTC should be diagnosed first following the correct diagnostic procedure outlined in the Workshop Manual, Section 303\-07B.
- [TSB 22\-2302](/bulletins/10216466.md), 2022-07-28, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION. Some 2018\-2020 Mustang vehicles equipped with a 5.0L engine and an MT\-82 manual transmission may experience a loss of movement and/or difficulty shifting. This may be due to excessive wheel hop which is caused by aggressive acceleration at low speeds while using launch control. To correct the condition, follow the Service Procedure to replace the failed components and replace the peak torque limiter.
- [TSB 22\-2280](/bulletins/10215717.md), 2022-07-18, Service bulletin: EQUIPMENT; POWER TRAIN:MANUAL TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\); POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\). Some 2020\-2021 Mustang GT500 vehicles may experience erratic and harsh shifting at highway speeds and/or perceived lack of power when accelerating from a stop, with a powertrain malfunction \(wrench\) indicator and diagnostic trouble codes \(DTCs\) P1601 and/or P061A stored in the powertrain control module \(PCM\) while using SelectShift. This may be due to the software in the PCM. To correct the condition, follow the Service Procedure to reprogram the PCM.
- [TSB 21\-2315](/bulletins/10201905.md), 2021-10-05, Service bulletin: POWER TRAIN; POWER TRAIN:AUTOMATIC TRANSMISSION. Some 2017\-2020 F\-150, 2018\-2021 Expedition/Navigator/Mustang and 2019\-2021 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 wear\-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 49821](/bulletins/10194428.md), 2021-06-01, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION; ENGINE AND ENGINE COOLING. Some 2015\-2021 Ford and Lincoln vehicles may exhibit an illuminated MIL with diagnostic trouble codes \(DTC\) P0011, P0012, P0014, P0015, P0016, P0017, P0018, P0019, P0021, P0022, P0024 and/or P0025. This may be due to small debris causing the VCT solenoid to stick. Before attempting any component diagnosis or replacement of the VCT solenoid, refer to Powertrain Control and Emissions Diagnosis \(PC/ED\) pinpoint test HK11 to cycle the affected VCT solenoid 10 times to attempt to clear the debris. For claiming, use causal part 6M280 and applicable labor operations in Section 10 of the Service Labor Time Standards \(SLTS\) Manual.
- [SSM 49292](/bulletins/10181931.md), 2020-11-04, Service bulletin: ELECTRICAL SYSTEM:SOFTWARE; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\). Some 2018\-2020 Ford and Lincoln vehicles may exhibit inoperative remote features via the Ford Pass/Lincoln Way mobile app, incomplete user authorization, no modem electronic serial number \(ESN\) displayed or DTCs U2100 and/or B156D in the telematics control unit \(TCU\). These symptoms may persist even after performing a TCU software update and/or replacement. To correct this condition, start a new session with the latest version of the appropriate diagnostic scan tool and perform a PMI on the TCU. If issues persist, open a hotline assistance request and include the IDS version \(if applicable\) used to perform the PMI and the Authorization Status PID value in the TCU datalogger. For claiming use causal part 14H092 and applicable labor times in Section 10 of the Service Labor Time Standards \(SLTS\) Manual.
