G56 Drain and fill plug Allen wrench size?

[AHill100]

Can anyone tell me the drain and fill plug allen wrench size for the 2006 G56 manual transmission? I need to go buy one right now.



I went to go change my fluid and found I don't have an Allen wrench large enough.



This big truck is forcing me to get larger tools

Never mind, got my answer. It is 14mm.

Geno's Garage has a real good price on that and the fuel filter socket. While you're at it,order Fleetguard filters at a fair price with real inexpensive shipping+no tax. Good folks.

The method I used on my personal truck and one at work was to take bolts of the correct head sizes and installed double nuts lined up and tight together and then weld the ends. 17mm on NV5600 and 14mm on G56. yeah I know its kinda cheesy but its cheap and very effective.

That is a good idea.
