What's with the triple square socket head on my gearbox

[WhipE350]

I got the bit in a 4 pack at Northern Tools. It was called a '12 Point Bit Set'. I found it entertaining Porsche used it, kind of like they didn't want just anybody pulling the transmission. I'm sure there is some other reason for using it, maybe someone on the forum knows. It is only torqued to like 33ftlbs or something.

I was wondering the same thing you were, why not just replace it with something a little more common. I'll ask my parts guys tomorrow see if he has any theories.
