This adapter kit is designed for exclusive use with the Ford AODE & 4R70W / 4R75W automatic transmissions. These 4 speed, overdrive transmissions were introduced during the 1992-2003 model years. It is very important that the new main shaft furnished is compared to the original main shaft being replaced.

This automatic overdrive transmission has become very popular among Bronco owners. The gear ratio found in this transmission is great for trail and highway use. We manufacture adapters for both the early and late model AOD transmission. This transmission assembly is 1-1/2” longer than the stock V8 assembly. It requires relocation and modifications to your stock crossmember. The adapter kit comes complete with an adapter housing, main shaft, spud shaft, bearings and seals.
