AOD- Master Kit (Edited).jpg


Ford AOD Transmissions

Black Series

Release oil for the overdrive servo in Ford's AOD, also happens to be apply oil for the direct clutch.  Normally, the tight fit of the pin in it's bore seals the oil, allowing the transmission to use the servo's release as an accumulator.  The problem is that as the servo applies and releases, the pin wears the case.  This wear in the case creates a gap through which forward clutch oil leaks, causing a lack of apply pressure to the clutch and release pressure on the servo.  With these losses of pressure, the transmission's service life, even after a rebuild, is seriously shortened.

The AOD kit contains all tooling necessary to repair the overdrive servo pin bore. It is a BLACK series kit, and is available as either a Master (pictured) or Sub kit.
