Service bulletin SSM 49416

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.

NHTSA's summary

Some 2020-2021 F-Super Duty vehicles equipped with a 6.2L or 7.3L gas engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0339 stored in the powertrain control module (PCM) or the vehicle may exhibit a runs rough concern with no DTCs. This may be due to a concern with contamination on the crankshaft position (CKP) sensor. If pinpoint test JD in the Powertrain Control/Emissions Diagnosis (PC/ED) Manual leads to CKP sensor replacement, inspect the sensor for contamination and document the results in the warranty claim. Use causal part 6C315 and utilize labor operation 12650D57D in the Service Labor Time Standards (SLTS) Manual.

SSM 55218	2026-10-06. Service bulletin. For 20202026 vehicles equipped with the 10R140 transmission, a new Transmission Clutch Circuit Leak Test has been introduced in the Ford Diagnosis and Repair System (FDRS). This test utilizes the pressure and vacuum transducer (PVT) when available. Workshop Manual (WSM) updates related to this diagnostic procedure are planned for release in Q4 2026. The new test improves the accuracy of detecting leaks within transmission fluid circuits and replaces the previous air check method. The previous air check procedure has been shown to produce a high rate of false positives, which may lead to unnecessary repairs when no actual leak is present. Accordingly, the air check procedure is not to be used for diagnosing internal transmission hydraulic leaks or as justification for transmission replacement.
