Decent mileage from that beastie.

I'd absolutely go for a manual swap if you're game for it. You correctly point out that the bigger benefit is the added control it gives you over gear selection (also, engine-off coasting potentially).

Sounds like a fair amount of your travel is highway, so you no doubt have been thinking about aero mods as well. There's some low-hanging fruit to be picked there.

EDIT: Your rear window area is obviously very abrupt, so you'll have flow separation way up high. But with the slight downward curve of the trailing part of the roof, and the huge length of that XXL cargo compartment hatch ... I mean trunk lid ... I wonder if you have some flow re-attachment there. I'd be noodling about that area as well.

Welcome to the forum!
