Sir, it does answer your question. On many vehicles, they don't have a dipstick. Instead, it has a fill plug and a drain plug. The fill plug is basically used as an overflow. Transmission fluid is filled through this plug opening and once it is full, it overflows from that plug.
When filling, the engine needs to be at operating temperature. The fluid level at that point should be at the base of the drain/overflow plug threads.
Since your vehicle does have a dipstick, that is how the level is determined and where it is filled. It won't have an overflow/fill plug.
I have no idea what you mean by, "emergency brake and traction control."
I hope this helps. If I still misunderstood what you are asking, let me know.
