# Service bulletin TSB 20\-2253

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: 10179116
- Published by NHTSA: 2020\-09\-02
- Manufacturer's number: TSB 20\-2253
- Manufacturer's date: 2020\-08\-12

## NHTSA's summary

Some 2018\-2020 Expedition/Navigator two\-wheel drive \(2WD\) vehicles may exhibit a clunk noise from the driveshaft area when shifting from REVERSE to DRIVE or DRIVE to REVERSE and/or during coast down. This condition may be caused by a slip/stick condition at the transmission output flange/anti\-ting ring interface. To correct the condition, follow the Service Procedure to apply a light coating of grease to the anti\-ting washer and output shaft splines.

## Other bulletins for the same vehicles and component

- [SSM 54366](/bulletins/11025611.md), 2025-11-19, Service bulletin: POWER TRAIN; ELECTRICAL SYSTEM. Some 2015\-2021 Ford and Lincoln vehicles may exhibit an illuminated MIL with diagnostic trouble codes \(DTCs\) P0011, P0012, P0014, P0015, P0016, P0017, P0018, P0019, P0021, P0022, P0024 and/or P0025. Pinpoint test HK in the Powertrain Control and Emissions Diagnosis \(PC/ED\) or in Section 303\-14 of the Workshop Manual \(WSM\) has been updated to address this concern.
- [TSB 25\-2476](/bulletins/11024877.md), 2025-11-04, Service bulletin: POWER TRAIN. This bulletin supersedes TSB 25\-2132. Reason for update: update the Part List Description and Labor Times Description Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: \* Harsh engagement \* Delayed engagement \* Harsh shift \* Delayed shift \* Illuminated malfunction indicator lamp \(MIL\) with 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 axial movement of the CDF clutch cylinder \(7H351\) sleeve causing hydraulic circuit leaks. NOTE: If internal transmission service is required to address a concern detected with the CDF clutch cylinder following this article, technicians should carefully inspect and replace other transmission components and flush transmission fluid cooler only as necessary to confirm proper function. Add a new line to the repair order
- [SSM 53764](/bulletins/11018521.md), 2025-05-21, Service bulletin: POWER TRAIN; ENGINE. Some 2020 Continental, 2020\-2024 Edge/Nautilus, 2020\-2025 Explorer/Aviator/Escape/Corsair/F\-150/F\-Super Duty/Ranger/Transit/E\-Series, 2021\-2025 Bronco, and 2022\-2025 Maverick vehicles may require an engine cooling system flush to be performed for various concerns. Workshop Manual \(WSM\), Section 303\-03 has been updated to eliminate the need to remove and install the radiator assembly to perform a radiator flush.
- [SSM 52548](/bulletins/11000297.md), 2024-05-23, Service bulletin: POWER TRAIN. Various vehicles equiped with 10R80/10R80 MHT/10R100/10R140 transmissions may require replacement of the seal kits \(7153\) when internal repairs are being performed. These kits come with 4 wheel drive \(4WD\) seals and will no longer include the 2WD seals. When working on a 2WD vehicle, any 2WD seals must be ordered separately. Refer to the parts catalog for the proper 2WD seals required.
- [22M03 S1](/bulletins/10253963.md), 2024-05-02, Service bulletin: EQUIPMENT. Certain 2017\-2020 Model Year Continental and Super Duty, 2018\-2020 Navigator, 2020 Aviator, and 2020 Explorer Vehicles Replace Front and/or Side Cameras if Foggy
- [TSB 24\-2101](/bulletins/10252674.md), 2024-04-04, Service bulletin: POWER TRAIN. This article supersedes TSB 24\-2046 to update the Service Procedure LTIS statement. 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 \(DTC\) that are stored in the powertrain control module \(PCM\) or transmission control module \(TCM\). This may be due to the transmission solenoid ID strategy, sticking valves in the main control valve body and/or axial movement of the CDF clutch cylinder \(7H351\) sleeve.
- [SSM 52314](/bulletins/10251934.md), 2024-03-20, Service bulletin: POWER TRAIN. During service and repair requiring removal and replacement of a crankshaft bolt and/or crankshaft damper, achieving proper torque of the crankshaft pulley bolt is critical. Incorrect torque may allow the bolt to loosen resulting in the timing gear breaking and engine damage. Replacement of the bolt is critical to the repair and accurately following the installation procedure in the Workshop Manual \(WSM\) Section, 303\-01 is extremely important. The bolt torque procedure can be found in the crankshaft front seal removal and installation procedure or in the engine assembly procedure.
- [TSB 24\-2046](/bulletins/10251469.md), 2024-03-07, Service bulletin: POWER TRAIN; ELECTRICAL SYSTEM. This article supersedes TSB 23\-2350 to update the Issue statement and the Service Procedure. 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 \(DTC\) 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 the transmission solenoid ID strategy, sticking valves in the main control valve body and/or axial movement of the CDF clutch cylinder \(7H351\) sleeve.
- [TSB 23\-2366](/bulletins/10246142.md), 2023-12-05, Service bulletin: POWER TRAIN; STEERING. This article supersedes 22\-2475 to update the Issue Statement and Service Procedure. Some 2018\-2021 Navigator vehicles may exhibit a grinding, growling, or clicking noise or inoperative power steering column during telescoping/raking operation. This may be due to a body control module B \(BCMB\) software issue. To correct the condition, follow the Service Procedure to reprogram the BCMB module and replace the steering column telescope or rake actuators.
- [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.
