Base 370z 7AT vs. Sport Package MT

wstar

In their defense, the MT is superior in some ways to the AT for real driving. It's lighter, slightly more efficient at transferring power, and the shifts are faster and more predictable. Also, they can drop out to neutral at any time, and then resume in the gear of their choosing.

I really like my 7AT, it's one of the best AT's I've ever driven. Torque multiplication from the converter is handy, it shifts reasonably fast, and it does have a lock-up system for efficiency. After spending 10 years commuting behind the wheel of a 6-speed machine, I just decided I didn't want to do that anymore in traffic. For a dedicated track car, it's the 6MT without question though.

What we can probably all agree on is we'd rather swap them both for a DSG-type system like the GTR has, or Porsche's PDK thing.

You dont have the car I have....yes the base specs are the same.....but my tranny is tuned for FI and only a professional driver could even come close to shifting as fast as the 7AT in my car. Every car that has been on the dyno at Z1 that was 6MT, with the same TT, boost pressure, and similar mods, put down the same WHP or less than my car. So, how are they more effiecient at transferring power? And again, how are their shifts faster and more predictable.

You sound like you regret your choice in the tranny you have......I dont. My final point is, if you look at the 1/4 mile times posted on the forum and reported by the major car mags, the 7AT is faster EVERY TIME. Now take that and help me understand how your facts work????
