As far as I know, the 7AT won't downshift to a gear that would put the engine above the redline - more than likely your RPM gauge needs adjustment or something.

Hm.. Interesting... It seems for me now as I try to remember that the car adjusted itself indeed as suddenly the power dropped but I remember well that I have seen the pointer in red zone...

...however the interval I have seen it there was very short. Maybe half a second or less.

500rpms over the redline probably won't cause any issues.
I don't know how the 370z motor is, but if it went past 8k you could bend a valve, bend a rod or a number of other issues.

If it was under load you could definitely bend something, but if you're downshifting then it shouldn't be under much load.

of course thats bad. thats what i did to my type R and ended up ruining my syncros which causes grinding in 3rd. i had to replace the rings which the body shop did a crappy job of when they had to open up my transmission and it was never the same since.... so be careful ^_^

An interference motor is when the pistons can hit the valves. Either from a broken timing belt/chain or if the motor is spun too fast and the valve springs cannot pull the valves back fast enough.

Some motors have either reliefs cut into the pistons or the combustion chamber is large enough to allow for clearance. It has nothing to do with tranny or options, but rather engine design.

If we have an interference motor and you spun it too fast, you can get minor valve/piston damage. But it sounds like you are going to be fine.
