You're exactly right about all the confusion AND theories. Of course I have mine, also. I SUSPECT that VW put the plug in backwards on the AT engines so that if the flex plate flexed too much it could not wear through the face ofÝè#˜g. Such flexing would be impossible with the flywheel, but MIGHT turn an impending failure into an immediate one in an AT engine. > from what i have heard, the plug was just placed backwards for ease of > identification of what engines to install the Flex plate for the auto > trannys......... a lot quicker to look at a cam plug, then to look at an > identification card/sheet....... Yes, this is true, but the AT cases already have an extra cutout at the bottom of the case that is just as easily visible from the front end AND it is still visible after the plate/flywheel is installed, so it is possible to VERIFY that the proper piece was installed. Actually, I think most of this is moot, because I suspect that AT and MT engines/trannys were probably built up either on completely different assembly lines, or on different days or weeks. Thus further minimizing the possibility of error by having only the proper parts for that day's production available. The most important point here is that ALL this is speculation.
