• Description:

  This is a genuine Ford automatic transmission mount bolt, catalogued under base number S439 hardware, used to secure the transmission mount to the transaxle and supporting structure on the Escape. The bolt clamps the powertrain mount in place, locating the transaxle and helping isolate engine and transmission vibration from the body so the driveline stays properly positioned under load. As a structural fastener in the mounting system, it carries powertrain reaction forces during acceleration, braking, and shifting. Owners typically replace this bolt during a transmission mount or motor mount service, when the original bolt has been removed and cannot be reused, or when chasing a clunk, excess driveline movement, or vibration traced to a failing mount. This is a single-use torque-to-yield style fastener that must not be reused once loosened, since reinstalling a stretched bolt risks loss of clamp load and mount failure. It fits the Escape with the various four-cylinder and hybrid powertrain options that share this M16 mounting hardware. Manufactured to Ford specifications, it matches original thread form, grade, and finish and installs in the factory location without modification. Always install a fresh bolt, tighten to the published mount torque sequence, and inspect the mount, bracket, and surrounding structure for cracks or distortion before final assembly. Verify placement against the powertrain mounting diagram for the specific engine before installation.
