If similar to the face lifts, an auto would be 4.2. Maybe uncle Jimbob could confirm.  :y

Sorry, specifically the 2.6 auto. The drive by wires are listed in FAQ for the correct gearing. I would think the 2.5 would be the same. But that's an assumption.

I can honestly say that I have no recollection of that thread at all, or even why I asked the question. :-[
Looks like 4.22 is correct then. :) Thanks all. :y

There's a plate on the diff with different markings/digits on it and somewhere on this forum there's a table telling which code is which ratio...
