Hi Jim,
I know about the Porsche since they are a similar to the way the old VW's were done for a mid engine.
I'm still having a real hard time getting my head around the top to bottom flip though. Assume there is a cad file showing the centerline of the input shaft that traverses through the length of the trans, that line is the rotational axis....correct? Assuming the input shaft rotates in a clockwise direction looking at the trans from the input shaft end, the rotation of the input shaft will not change by simply rotating the trans upside down...will it?
Anyway here is a jpg showing what I mean.
Now don't get me wrong, I know nothing of the transaxles but I am trying to learn and that is why I'm here on this forum. You have excellent technical info period!
Mike
