The 88 and newer Ford automatic overdrive transmission (AOD) has improved lubrication and is more capable of handling the V8. This trans is both larger and longer than the 3spd and will require the crossmember to be moved back approx. 1.5”, requiring driveline modification, a possible body lift or modification of the transmission tunnel braces. This kit consists of an output shaft, tail housing and a special spud shaft. Disassembly of the transmission is necessary for installation and it’s recommended that it be done by a trained technician.
