Hi!
Going to change the diff and gear box oil soon. Poking around, I've found these pretty useful:

Condensing what I've pulled together, from the above and other places:
* No focus on brands. 5 liters of full synth 75W90 oil is right for the 6MT diff and gear box.
* Have a T70 bit handy
* It doesn't really matter about the torquing the plugs. If it was tight, put it back on tight
* Undo the top plug on the rear diff first
* 1/2 drive will undo the rear diff sump plugs
I'd like to ask if the GTB has the same "issue" with the exhaust in the way of the top plug?
It all seems easy...
Cheers!
