Ok, What have I done now... (904 problem?)

running it a quart down isnt going to hurt it. make sure you are on level ground, engine hot and in neutral. keep checking it. a tad overfull isnt going to hurt either. if you are even a pint underfull it is going to feel lazy. just yesterday, my 727 was feeling slightly lazy, i checked the fluid, sure enough, a pint down, i topped it off, back to normal. i use nothing but pure synthetic ATF.
