automatic 트랜스미션오일이 크게 두종류로 나뉩니다. 트랜스미션종류에 따라 맞는 오일을 쓰지 않으면 트랜스미션이 오작동할수 있고 수리비용이 많이 들어가게 됩니다. 요즘에는 각 회사별로 자기네 오일을 써야만 한다고도 하는데 아래 깨알글씨로 다른 타입도 급하면 사용할수 있다 등으로 명시되어 있습니다.
대개 종류는
* ATF+4 – Most Dodge, Jeep, and Chrysler [1]
* Mercon V – Most Ford, Mercury, Lincoln
* Mercon LV – Some Ford(DuratecHE),MAZDA in Europe or Asia
* Dexron VI – Most GM products, some Ford applications
* ATF-Z1 (Being phased out as of 2011) – All Honda and Acura (except CVT)
* ATF DW-1 – All Honda and Acura (except CVT)
* SP-III – All Hyundai, Mitsubishi and Kia (except CVT and dual clutch)

토요타나 타 회사에서 GM 트랜스미션을 사용했다는 것이 아니라 같은 오일을 사용하도록 설계되어 있다는 뜻입니다.
