i was wondering---is there a uniform access hole for the torque converter bolts on a m50 equipped 525i with the a4s 310r transmission? bentley suggests two different possible holes for these bolts. i'm assuming that there are three or four bolts that have to be rotated around to access somewhere from the back of the engine. do you use a wrench to rotate the crank to do this? one suggested hole is located in the sump, another is through a removable access hole cover, and i'm hoping that there is a definitive answer.

just fyi--i'm trying to remove the transmission from the engine/car to replace the bell housing to main body gasket in the transmission. i've never removed the transmission from this car, so any hints or even rudimentary instructions would really be appreciated. thanks.
