Which plug on the G56 do I use to check the gear oil level? There's one plug on the drivers side and two plugs on the passenger side of the transmission. On the passenger side plugs, one is higher on the case than the other. Also, what Torx bit size do I need to remove these plugs? Thanks for y'all's help.

 

Hope this helps...Not sure of the Torx size, but it looks more like a hex, too cold to actually check.

 

Passenger side TOP of the G 56.. THe drain is at the very bottom...
