Ford AXOD, AX4S, AX4N, & 4F50N Transaxles
Apply oil for the Overdrive servo on AX type transmissions comes up through the servo pin bore and through the hollow pin to the back of the piston. This requires the pin to seal in the servo pin bore to apply the servo and achieve fourth gear As time goes by and the servo goes through many apply and release cycles, the case wears and the pin no longer seals. This wear causes apply oil to leak, dumping pressure. With this loss of pressure, the servo lacks adequate pressure to hold the band completely applied, burning the band.
The AX-OD 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.
