Great discovery—I asked myself this question over the weekend while contemplating some ideas:Just got done with the PPE 10R140 Deep Transmission Pan install. Can confirm the cooling fins hang lower then the cross member, you could get them machined flat however.
Seems they matched the level of the 6.7 Oil Pan.

Why does the rear portion of the skid plates I’ve seen hang lower and not sit flush to the cross member as I think it should; to accommodate a deeper pan?
