C55 transmission only a 5spd, lets make it interesting.....
+1, had a CVT on a Honda HX (High Fuel) and it was awful.................it was a DD, not even that great on gas.........

I still don't get this. You can't just "add a gear." You'd have to add the programming, etc to be able to use the extra gears. It would be my guess you'd be looking at in excess of $10,000 for fab. The only option would be to retrofit, I suppose. And even that sounds like it could be $5-$10k min by the time you source parts, and have somebody put the whole thing together.
If your after lower RPM's on the highway, I'm not even so sure a 7-speed will give you that. I suppose it would in an IDEAL condition (ie 0% grade up/down, constant speed, constant traffic, etc). I've found the new 7-speeds are so close to a 6-speed that even the slightest throttle change induces kickdown to 5th or 6th.
Just get a different car
But a 6spd man would be great, i know it would be a joy to drive
