I checked on the way to work today. At cruise, in D, the 7AT is 2250rpm @ 70mph in 7th gear. This actually lines up almost exactly with the theoretical. Final drive ratio in 7th gear is 0.77. The radius of the stock 18" sport rims and OEM tires is 13.5", give or take. Do the math and you get 2264rpm@70mph. 6th gear would be about 2530rpm and 5th gear about 2940rpm.
The crazy thing is that red line in 2nd gear would be 93mph and you would hit the speed limiter in 3rd gear, right about 7500rpm.
Checked on my way home from work tonight and I have to agree... it was around 2300. I'm not getting as technical as to extrapolate the final drive ratio...

LOL!
I just pulled the drive ratios from the owners manual.
