hey I have a honda civic ek5 with a d16 engine
i wanna know what kinda ATF oil I should use on the dipstick i see dextron
what kinda is best brand for the gearbox

 

The best would be genuine Honda ATF, though it is expensive. You also should be able to find Honda-recommended ATF at your local auto parts stores. The label must say that the ATF is compatible with Honda automatic transmissions.
