Wooffi...perhaps you're trying to access the crankshaft nut from the top. I haven't tried from there but you CAN reach it from the bottom, at least it is possible on the 300D. I believe that I read that there is even more room with the 204D. I didn't have a 27mm socket but if my memory serves me...a 1 13/16" will get you by for all the more cranking you'd be doooin.

ps...I'll take the purple wire first anytime...but I'll have to admit that when I was doing the drain the torque converter bit...I got soooo close with the purple wire but not good enough... and rather than going around mucho times more....I got out the socket and gave it a little nudge.....
