To get to the fill plug is a desaster on that trans, I did that today on an E46 with this 5L40-E, got the fill plug finally open with this modified tool someone made a yutube https://www.youtube.com/watch?v=KWFauhfzKJw
Whenever you intend to do a filter and ATF change on this trans, FIRST always try to get the fill plug removed! Otherwise you might have a empty trans pan and cannot refill it
