904 help

So i added a quart more and now is about 1/4 in over full on the dipstick. Shifting from 2-3 has greatly improved! thank you for that. One thing is that cruzing at 40 and flooring it does not result in kickdown to 2nd. I verified that the linkage is being pulled as far back as it can go at WOT, and adjusted the kickdown band to 2 turns out. So the question is if it should kickdown there? will it only happen at slower speeds? or something still not right. Thanks again for all the help.
