7A Transmission...dare I commit heresy?

Uh... it really does shift as fast or faster than 95% of people can possibly clutch in clutch out... recorded with Osiris software. Also faster in average 1/4 mile and 0-60 times, which corroborate with that. Maybe you test drove one that isn't in good repair?

It's also influenced by trans fluid temp and throttle position, so if the fluid was cold and you didn't give it much pedal, it might feel a bit more granny shift-ish.

Also best to have VDC off.

And throttle response on both AT and MT needs to be tweaked.

Anyway, like I said, you can turn the shift speed and firmness waaaay up with Osiris.

I'd try a different one or see if someone around you has a tuned one to play with before you decide... That said, if you prefer a MT, go for it!

Any downsides/risks involved in making the shift speed quicker with Osiris?

So far, none found by me or others who have done it.

Will definitely take a bit of getting used to tho'. I have it tuned to bang hard into gear above 1.5 K and 1/4 throttle or more, although it can be tuned however you like.

With remapped throttle responsiveness and retuned shifts it is a wild beast off the line now

And I thought it was a wild beast off the line before......wonder how much this will help my 1/4 mile time. I'm usually near the top of 4th gear by the time I get down the 1/4 mile.

I drove a new 2012. It was cold out, but I could tell that wasn't the issue. At part throttle, it just takes time even in manual. I felt very disconnected. I'm going from a high ten/low eleven second car to this, so a tenth or two in the 1/4 is the least of my worries. I just want the most fun, and after driving the a7, I personally, for me, feel that m6 is the way to go for me. I'm not taking a swipe at the a7 other than to say yes it was a tad indecisive, its just not my thing, but I wanted to give it a go rather than regret it later.

Oh yeah, I had VDC off day before yesterdayand tried this: Shifted to manual mode @ 50 Car went into 5th. Double pulled the -shift paddle punched the gas. Lit up the tires for about 10ft in 3rd while thrusting the car forward with great attority. I didn't expect that. I was truly impressed. It's all about learning what and how to accomplish what you want out of the S7.

That's brings up others features and quirks worth mentioning that aren't in this thread:

You can multi-click the paddles before a shift completes and drop down (and presumably up? never tried) multiple gears much faster than waiting for each to complete.
If you're driving in D-mode, the gear indicator on the dash just shows "D", so if you're not paying careful attention to every little gentle shift you won't know exactly which gear you're in, especially at low speeds/rpms/throttle.
If D happens to be in gears 1-5, it generally stays in the same gear if you flip the control to M-mode. If D happens to be in 6 or 7, it downshifts to 5 when you flip the control to M-mode.
You can also use the paddle shifters to temporarily change gears while in D-mode, and it will revert to full-auto after you leave them alone for a bit.
You can defeat the auto-downshift from 7 -> 5 when switching D -> M at highway cruising speeds by clicking the upshift button first (which goes to temporary manual mode and stays in 7), and then moving the selector to M.

Note: I hardly ever use D-mode, so I could be slightly wrong on details there, but that's what I remember

This! Soo much better than flooring it and waiting on the tranny to downshift. When hitting an on ramp just click the left paddle twice and punch it!!
