Transmission Adapter Kits

ATI adapter kits allows Ford and Chrysler owners to benefit from the GM transmissions as well. Before the ATI adapter kit, many hours of expensive fabrication were necessary to mate GM transmissions with non-GM engines. With the introduction of the ATI adapter kit you now can perform the operation in less time with less fabrication required. The ATI adapter kit includes an ATI adapter plate, an ATI crank adapter, an ATI Flexplate, and all the necessary mounting hardware to correspond with your Ford or Chrysler engine.
