GENERAL INFORMATION:
This adapter kit can be used for the Bronco II V8 engine conversion installations that are replacing either the A4LD
automatic transmission. The overall length of the new AOD transmission case plus the length of the new adapter housing
will be the same overall length as the original A4LD. If you are attempting to use this transmission for replacement of the
original 5 speed, it may be necessary to modify the drive lines and transfer case location.
Every attempt has been made to duplicate the original AOD tailhousing. Before final assembly into the vehicle, you must
verify that the shift linkage clearance in the tailhousing is sufficient. A test on the linkage lever will make sure that the
proper clearances have been achieved.
The transfer case adapter has been furnished with a transfer case linkage mounting holes and crossmember support holes
identical in location to the original A4LD adapter. Slight modifications may be necessary.
The new shaft that we have supplied with this kit fits Ford AOD transmissions 1988 and newer AOD transmissions. In
1988, Ford made some major changes to the oiling system that required a different main shaft and different valve and spring
kits. We have talked to a few different transmission shops concerning the requirement that all transmissions must be
equipped with the newer style shaft. It is the general consensus that this new design be used on the high performance
type applications, but for most installations, the older style shaft and governor assemblies are adequate. We have attached
a reprint article from SUPER Ford dated May 1990, that discussed the necessary changes and the advantages of using
the newer style shaft. We have also attached the information supplied by Ford Motor Company for changing of the valve
and spring assemblies when using the newer style shaft.
