I heard Ford is looking into an 8 speed for the Power Chokes at some point. I really don't see the need for all these gears. They are going to have these things acting like fully loaded big rigs taking off from a stop having to go through every gear whether it needs to or not. 5 evenly spaced gears is more than sufficient. They need to bring back the 4L80E and figure out a way of adding a .67:1 double OD to it. That would be just about as perfect as you can get IMO.

Why would you need 7 gears in a car that is going to be light weight and high hp???? Are they afraid that the engine can't handle it? The ZR1 (and Z06) both handle their long gears with ease which is one of the reasons they are so quick. 1st gear to 60+ mph?!?!!! Why slow the car down with more gear shifts?

More gears allows the engine to stay within a narrower power band each shift. Ask a big rig trucker who knows how to drive a 10, 12, 18 speed manual. Allowing the trans to do the torque work instead of the engine means you can make the engine less powerful. A less powerful engine can be smaller, lighter, and more fuel efficient. Additionally, without long gears to pull the engine doesn't need to pull to the moon in it's RPM band....so cheaper internal parts. Together the trans and engine combo provide the same performance excitement with less fuel consumption and for less money.
As for the gear hunting. It's a matter of the tune/calibrations, not the trans. I've spent 2 years tweaking my 6L's and I've had it go from refusing to downshift to dropping a gear or two with a slight twitch of my foot. You guys hating the 6spds need to find yourself a local and knowledgeable tuner to tweak it. Trust me...once it's done right, you never wanna drive a 4L70 trans vehicle again.

Just look at any lambo vs z06 or zr1 video's on the internet. While the lambo driver is rowing a boat shifting gears the vette is shifting much slower. Its just using the tq that the engine was designed to use unlike the high reving lambo that has a small power curve.
I understand the big brother fuel regulations.....thanks government for over regulating and sticking your head into things they (government) don't understand.
