not saying the 6MT is better than the 7AT, to me its personal preference. both make great sports cars.

I drive a SST and the new 7 speed AT on the 370Z. I got to say they are dame close!

The shift speed of the 7AT is advertised as 500 milliseconds. This is very very fast for a slush bucket tranny. Most are closer to the 1 second range.

Damn...500 milliseconds ain't bad. It would have been better if they shaved that down to half a second, though.

That is half a second.

WTF are you talking about?

500 of something can't be the same as half of something else.

Huh???

does 500 not equal 1/2 of 1000 //// 1000 equal half of 2000

P.S. 500 miliseconds = 1/2 second

I'm sure pretty soon, there will be a "SRM vs. natural downshift or heel-toe" thread...it's a preference, and I prefer the 6MT after almost trading it in for a 7AT...nothing against the 7AT, it's a great tranny, but I prefer just raw moving parts over an electronic limiter

"over an electronic limiter" - what the heck are you talking about?

JoeD · 10-14-2009, 09:00 PM

Does the 7AT double-clutch on up-shifts? My homeboy in auto-shop class who knows a lot about cars said that double-clutching is a must if you want to go faster.

theDreamer · 10-14-2009, 09:02 PM

No, the Z does not have a double-clutch transmission.

Wait...so you need a double-clutch transmission to do it? He has a '94 Prelude and he swears it's hella faster when he double-clutches, but I don't think he has changed the transmission. He says he beat his homeboy's dad's Mustang GT if he double-clutches, but he loses if he doesn't. I was just wondering if the 7AT could do the same thing. Is there a button you can press for it or something?

theDreamer · 10-14-2009, 09:12 PM

You want it to be half of 500 milliseconds?

nogoodname · 10-14-2009, 09:37 PM

the Z will never have a dual clutch from factory.....
