My 2007 S80 has the Aisin Warner 5 speed automatic transmission and the drain plug has TORX DRIVE center which is partially stripped. It looks like a special hex shaped (as in allen wrench) with a hole in the center (tamper proof?) could be used to get the large plug out. Does anyone know a source for such a tool? I might have to fabricate something for it, huh?

 

That is actually a 2 part drain plug. The center torx bolt controls the level of the transmission fluid. To have to take that it out to get to the 17 hex which is the actual drain plug.
