G4

Ford 4EAT-G (G4A-EL) Transaxles

​

Blue Series

To release the Intermediate/Overdrive Band for the 2-3 shift on Ford's GEAT-F, 3-4 Clutch oil is applied to the inside of the servo piston.  The 3-4 clutch oil, with the aid of the servo return spring, overcomes apply oil, forcing the servo outward and releasing the band.  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 3-4 clutch oil leaks, causing a lack of apply pressure to the clutch and release pressure on the servo.  With this loss of pressure, the life of both the 3-4 clutch and the Band, even after a rebuild, is seriously shortened.

​

The G4 kit contains all tooling necessary to repair the overdrive servo pin bore. It is a BLUE series kit, and is available as either a Master (pictured) or Sub kit.
