Welding robot is out of order for an unknown period of time. But could do ~same(preciseness would be as precise as my eye is) with it’s hand would get coordinates out of it.If you have a transmission handy, I suggest taking it to a measurement facility that can use a FARO arm or something similar (it shouldn't cost too much). Scan the center and bolt pitch and even trace the outside of the transmission. You can then use the data in CAD to create an adapter. I've used these before, quite handy.
I don't think you'll find geometry anywhere - and frankly, I wouldn't trust the measurements.
