Hi, i think i will need some help here, ob my build. I am trying to figure out how to mount 5spd auto box on my BMW m57/6 inline diesel/ to maybe make better 1/4 mile run with the auto box and the standalone controller. What i need is mb 6 hole torq converter bolt patterns, and also if you know from what material is made the flex disk that is between flywheel and torque converter. Also thickness? I am asking because i dont have it, and i will need to make it ... and also i will need to make it fit my bmw bolt pattern on the crankshaft. 
also some off topic ... do you think this gearbox will improve my 1/4 mile time compared to manual gearbox?

I have my 606 with 722.3 out the car and apart from each other. I actually measured bolt pattern because I was also having problems. I thought it was two holes 4.3cm apart at 120 degrees. But I don't remember exactly. I can measure if you like?

I can tell you that the 722.6 uses various torque converters with different bolt patterns. 722.3 flexplate is the same as one of the 722.6 convertor ( for a petrol car I think) but it won't work correctly. Are you using 722.6 box?

Sorry I read your post now. The plate is about 3-4mm thick and made of steel. It's not a full disc. It has 3 arms' and cutouts. 6 bolts go thru the arms 2 per arm to bolt onto the convertor.
