A related, but different observation/question;
Mine is a manual. I'm surprised there isn't a taller gear in 6th - more like an overdrive. I spend a lot of time on the highway in 6h, at something over 4000 RMP's quite often. On the street, wouldn't the car benefit from a taller 6th gear? Is it a mod an experienced tranny guy could make?

I'll have to look next time.
