AT变速箱的专利基本被Aisin, ZF垄断了。要使用要么进口，要么交专利钱。但是匹配调教并不是花钱能买到的。

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.
