where to put autotransmition oil?

You need to be less short on information. What make and model of car are you talking about?
If it's an automatic the oil goes in the dipstick hole. But then if it's for example a Jag, it's a sealed gearbox. No oil filler. No need for one......
Some cars use the engine oil for the manual gearbox.
