AT變速箱的專利基本被Aisin, ZF壟斷了。要使用要麽進口，要麽交專利錢。但是匹配調教並不是花錢能買到的。

Aisin -- Japanese company (Toyota is the owner), supplies automatic transmissions to 55 automotive manufacturers around the world, virtually every major OEM. These include General Motors, Ford, Jeep, Mitsubishi, Nissan, Saab, VW, Volvo, Hyundai, MINI among others.

ZF -- Germany company, BMW and lots car makers use this AT, Chrysler Group LLC initially received the 8HP 8-speed automatic transmissions from the ZF plant in Saarbrücken, Germany as well.
