Give the 7at some time.

Another problem was the shift speed on the old 5AT was so slow that the engine would overrev during the shift and hit the rev limiter on almost any FI application on the transmission (see some threads on it at my350z). You had to get a valve body upgrade (at about 1000 bucks) and reflash the rev limit higher to even start using that tranny and it was still weak. The new 7AT seems to be much better with faster shift speeds but it's kind of a wait and see. This tranny holds 390 hp on the FX45 w/o any problems and I assume it's gonna be somewhat over engineered.
