Why not get the transmission up to operating temperature first before opening the fill plug? (so you don't get fluid gushing out)
side note: with all the debate of whether or not to change the transmission fluid. (I personally i feel it's unsafe, especially if there are real-world stories of transmissions slipping after a flush)
*Why not drain and fill only 1 quart of oil every other oil change.* (to put your mind at rest, especially if your only concern is that the original oil loses its effectiveness over time).
