Service bulletin TSB 23-2138
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.

| TSB 26-2408 | 2026-09-30. Service bulletin. This bulletin supersedes 26-2309. Reason For Update: update the Model section to remove Aviator 10R80, update the Parts list to add 3.3L to W520514-S440, and add L1MZ-7Z490-G valve body separator plate for Aviator. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: * Harsh 3-4, 4-5 upshifts * Harsh 5-3, 4-3 downshifts * Harsh reverse engagements These symptoms may be worse when cold. This may be due to the F clutch friction plates brinelling into the clutch and planetary container cylinder (7B177). |

| TSB 26-2395 | 2026-09-01. Service bulletin. This article supersedes 26-2287. Reason for update: update the labor operation numbers to add MT to operations C, F, G, H, J, K, L and M, and correct the part number LIMZ-4A015-B to L1MZ-4A015-B. 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)s 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 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 ne |
| PT-26.13.13 F-150 Ltng | 2026-08-18. Over-the-air update. 25C69 Recall remedy - Updates the Secondary On-Board Diagnostic Module C to provide for release of the Integrated Park Module slider in the event a bind condition occurs allowing park to be engaged |
| SSM 55073 | 2026-08-11. Service bulletin. Some 2021-2026 Bronco vehicles may require the removal and installation of the transfer case for various reasons. Installation requires Loctite® 243 adhesive applied to the mounting bolt threads in the transmission. Make sure that the mating faces are clean and dry. Tightening the mounting bolts also requires an updated two-stage tightening sequence. Workshop Manual (WSM), Sections 307-07C/D and 308-07C/D Installation > Transfer Case have been updated to reflect this change. |
| TSB 26-2359 | 2026-08-10. Service bulletin. Some of the vehicles listed in the Model statement above may exhibit an incorrectly illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0420 stored in the powertrain control module (PCM). This may be due to the software in the PCM. |
| SSM55059 | 2026-08-03. Service bulletin. Some 2021-2023 F-150 vehicles equipped with a 3.5L PowerBoost engine, 2020-2026 Explorer vehicles equipped with a 3.3L hybrid engine, and 2020-2023 Lincoln Aviator vehicles equipped with a 3.0L EcoBoost hybrid engine may exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble code (DTC) P0A1E stored in the powertrain control module (PCM). The vehicle may be unable to enter electric-only drive modes as expected during normal drive cycles. This may be due to the belt integrated starter generator (BISG). For vehicles with this condition, follow the necessary Pinpoint Test in Workshop Manual (WSM), Section 303-06 for DTC P0A1E and repair the vehicle as directed. Note that previous replacement of the BISG does not negate the need for subsequent BISG replacements if directed to do so by the appropriate Pinpoint Test diagnostics. Engineering is investigating this BISG quality concern. Monitor PTS for updates regarding this investigation. |
| TSB 26-2294 | 2026-07-13. Service bulletin. This bulletin supersedes 26-2066. Reason for update: To remove "(2024 only)" from the Issue statement to include 2021-2025 vehicles that may exhibit a clicking sound coming from the gear shift lever. Some of the vehicles listed in the Model statement above equipped with a console GSM may exhibit at least one of the following conditions: * Clicking sound coming from the gear shift lever after it is placed and kept in reverse, neutral or drive position. * Gear shift lever stuck in park * Gear shift lever will not shift into park * Gear shift lever will not shift out of gear * Gear shift lever will not stow/unstow * Gear shift lever will move past the park position * Loose gear shift lever arm at pivot * Illuminated powertrain malfunction (wrench) indicator with DTCs P0929:77, P0929:00, P0929:07 and/or P0929:9A stored in the GSM This may be due to the GSM. Note: If the gear shifter lever will not shift into park, the transmission will automatically shift into park when the return to park function is triggered. |
| TSB 26-2304 | 2026-07-06. Service bulletin. This bulletin supersedes 25-2383. Reason for update: to add 2023-2026 F-150 2.7L vehicles. Some of the vehicles listed in the Model Statement may exhibit a vibration/shudder felt during light throttle tip in at highway speeds (8,9,10 gear) with no diagnostic trouble codes (DTC) present. This may be due to various software parameters in the powertrain control module (PCM). |
| TSB 26-2309 | 2026-07-01. Service bulletin. This bulletin supersedes 26-2241. Reason For Update: update the parts list to correct the claim quantity of the part number JB3Z-4B496-B from 3 to 6. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: * Harsh 3-4, 4-5 upshifts * Harsh 5-3, 4-3 downshifts * Harsh reverse engagements These symptoms may be worse when cold. This may be due to the F clutch friction plates brinelling into the clutch and planetary container cylinder (7B177). |
