Sometimes more than not it can be a challenge to locate a specific thread on this forum. Even if you go to a specific sub forum, if you don't have the wording exact, you may not be able to find the thread. One thing you can do is google a specific issue or subject related to the Ford Edge and it will direct you to a thread/post within this Ford Edge Forum. 

Great information todd92. The 2019-2024 Edge uses 75w85 GL5 as it is a totally different PTU than older models.

AWD and 4WD are very different. I don't think whatever you are trying to do is even worth trying. If you want 4WD, buy a vehicle with 4WD. What Edge and what year do you have. For example, the Edge ST has an AWD Sport Mode (double tap the ESC button) that makes the AWD system much more active and aggressive. What model/year do you have?

I haven't heard of a software configuration that could be manipulated by the likes of Forscan.   The RDU coupler can be disconnected which will make it permanent FWD.

No, they're not the same.

Ditto.  I mean, isn't AWD by definition 4 wheel drive?  I'm confused.

More Red X Changes

Do not know other than the new ptu will be changed every 30k.  The new one has a heat shield which may only do so much.  Extended the breather tube to allow for a super slow fill at the fire wall rather than killing self on the side.  Friend who deals with a lot of engine builds says for motor oil, the thin stuff is for corporate fuel economy, provides little protection, little mileage gains.  I am probably going to run 10 30 synthetic on the next oil change.
