Sometimes I love engineers. 2 and 4 wheel drive G56 units appear to be the same. 2wd units just get this big flange.
And sometimes I want to take a rolled up newspaper to engineers. There is only one sensor on the trans. I wanted to see if it was a reverse sensor or vss. It (and most of the bolts on the trans) are inverted torx metric. Bad engineer.....swat swat.....go to your corner and think about what you did.
It's a reverse switch by the way.
