• Description:

  This needle bearing supports the reverse planetary carrier inside the transmission case, allowing the carrier assembly to rotate freely while reverse gear is engaged and reducing friction and wear between the carrier and its mating surface. It is confirmed genuine Ford fitment for the 6R140 six-speed automatic transmission used in the 2011-2019 F-250, F-350, F-450, and F-550 Super Duty and the E-150, E-250, E-350, and E-450 full-size van and cutaway platforms. A vehicle that grinds, whines, or clunks specifically when shifted into reverse, hesitates before engaging reverse, or shows metal flakes in the transmission fluid during a reverse-clutch or carrier-related repair is showing the classic symptoms this bearing addresses once it has worn or begun to break down. Ford's catalog lists this as an internal bearing for the reverse carrier assembly, and replacing it requires the transmission to be opened and the internal gear train partially disassembled, so this is typically a step within a larger internal transmission repair rather than a standalone external service. Confirm the correct reassembly torque specifications and use the specified transmission fluid when the unit is closed back up, and inspect the carrier bore and adjacent thrust washers and selective snap rings for wear whenever this bearing is replaced, since a failed bearing often accompanies wear on the surrounding hard parts. No core charge applies to this bearing on its own, and no module programming is required since it is a mechanical component with no electronic content. Because the reverse carrier assembly is a rotating load-bearing internal part, follow the factory rebuild procedure and torque sequence exactly during reassembly to avoid a repeat failure.
