yah, they only know how to play atari 2600's...

Old farts.

Err... traditionalists?

Interesting thread so I am going to ask a dumb question also. What if scenario.. I am doing a steady 60mph and I then use the paddle down multiple times to go to first gear, will it over rev and do some damage?

No. It will not let you over rev, BUT when you get to the correct speed, it will let you downshift to the point where (for example) 1st gear runs to 7499 RPM.

The 7at is a great transmission that matches your revs when u downshift .i wonder how come they improve this on the z35 ?

Paddle shifting to me is not as smooth as any manual I've driven. But I'm sure it's operator error right now. Hard part is guessing when to shift since the 7at lags a little when shifting in manual mode. I've read that you should up shift about one to one half second before you would want to so it's smoother transition.

I have not had time to play with it yet

As DE.50 pointed out, the TCM will not downshift if it would take you above red-line (or maybe just a hair above). As with the throttle*, you are flying-by-wire and don't have direct control. The car has a pretty strong self-preservation instinct. But that doesn't mean you should be depending on the limiter and bumping the red-line every time you downshift; it will eventually cause damage.

* Another "neat trick": press on the brake and the gas at the same time - the car will auto-magically limit the throttle until you let off the brake.

Pretty sure it's not being limited by the ECU (as with launch control) but rather stays at that RPM because you've hit the torque converter stall speed (and stressing the trans).

I'd bet it's a function of the brakeover ride safety feature governed by the ECU.

Hopefully we get a watered down version of the gtr transmission. For the upcoming g z35

The odds of them putting a dual clutch box in the Z is pretty low considering how much they cost. As good as the 7at seems to be, I can't see them changing it much at all.

Well thanks for explanation. Today I downshifted from 4th to 3rd and I heard a slight bang under from car tranny area. Wasn't loud just a low thunk.

If you ever get it tuned with UpRev have them up the trans pressures over 4,000 rpm. That allows it do be smooth DD in auto mode but makes the shifting super fast and smooth when you are on it hard. It made major improvements to my car at the track.

any specifics or do I just say, hey uprev guy, up my trans pressure over 4k rpm?

I'm not sure what my numbers ended up but we didn't go up a lot. We took everything over 4k and raised them slightly then when out a drove the car hard. We did it several time until it felt great.
