Why no revised or updated transmission for the 07 G35?

I have *never* experienced an AT even close to the way this one performs.

From Autoweek:
Track-day drivers take note: Another on-track advantage was on the backside, No Name Straight, where both the German and Japanese competition found their six-speed automatics shifting up just when you didn’t want that, mere feet before the liftoff point. The Infiniti’s five-speed automatic may just have better gearing for the course, but its manual mode allows the driver to hold a gear right up to the rev limiter, not trying to out-think the driver.
From Edmunds:
"In the age of the six-, seven- and now eight-speed automatics, the Infiniti's transmission, with only five forward gears, may seem behind the times. But the five-speed's proper gearing, attentive action and ability to match revs perfectly when manually downshifted makes the transmission a standout and the perfect choice for this very capable sport sedan. It delivers all of the hard-driving advantages of BMW's complex sequential manual gearbox (SMG) without any of that transmission's drivability issues."
What's the more economical argument?
A) 335i and IS350 have 6 speed auto trannies, and get 2 mpg better than G35.
B) G35 has a 5 speed auto tranny, and is $3000 to $8000 cheaper than IS350 and 335i.

The new 6AT in the 335i is a *huge* advancment in AT technology.
It's not whether it's 5At or 6AT... gearing is gearing;
It's the lightning fast shifts & solid feel.
The new BMW AT is very SMG like in performance w/o all the other SMG issues.

I guess the only thing that stopped me from getting another manual was the fact that I would sometimes sprain my ankle playing sports and I wouldn't be able to commute to work.

All this talk about "how fast" the tranny shifts or doesn't shift makes me think you guys don't understand how a transmission works. The firmness of a shift, which is directly related to how fast it shifts, is based on the transmission line pressure. This is controlled by the ECU, the stock setting is very soft, for luxury purposes. On some of the domestic transmission like the Ford 4R70W, the line pressure can be changed by a $40 gadget made by B&M or by a chip, and viola you have very fast shifts probably faster than the new advanced 07 BMW 335i auto.

I don't need to drive it, i'm perfectly happy with my 05 G35 auto, the downshift rev matching is excellent and the converter is super loose. The shifts can be firmer but like I said that just has to do with the line pressure, the gearing is very aggressive already. Another thing that has to do with how quick the shifts are is the timing retard. Most stock cars retard the ignition timing in between shifts for more luxury as well as making parts last longer, take that out with an ECU tune and up the line pressure and you will have neck breaking fast shifts on your G35.

& if you think you're going to improve it with a $40 module, try doing some research first.
