Early Bronco AX15 5-Speed Manual Transmission

The Aisin-Warner AX15 transmission is a very successful, medium-duty, standard shift, five-speed transmission and is regarded as one of the best 5-speed transmissions ever installed. It was introduced in 1988 and is a great swap for many Bronco owners. The AX15 can be cleanly adapted to the Windsor Ford V8 bellhousing that features the "butterfly" Ford transmission bolt pattern with an adapter included in the Wild Horses kits.

The AX15 is a split-case, top shifting, overdrive transmission with the shifter being located in the rear section of the transmission. The AX15 is fully synchronized in all gears. All gears are helically cut. Gear ratios for the AX15 are: 3.83, 2.33, 1.44, 1.00, 0.79, for first through fifth, respectively.
