2014 370z automatic transmission - manual mode

JWillis72 · 05-05-2014, 06:09 PM

It's not a great video but my friend shot this on the last run. Before anyone complains it's in a closed business park on a Saturday with the gate locked at the end of the road. The shifts on it are almost instant now.

It slows downshifts though

I don't think it slowed mine at all but maybe it's because we didn't mess with below 4k.

You'd have to consult WStar, he had reasoning behind it, I dunno really, don't shoot, lol

According to Nissans site it only activates when the vehicle is in motion beyond a certain speed.

I use my manual mode exclusively in mine. I don't like the way the exhaust sounds in auto, or even in manual auto so I hit the paddle and then lift my foot off the gas. This makes the shift perfectly smooth both in transition and sound. Just like a real manual.
Its kinda hard to explain..

Paddles, manual modes, only 2 pedals... Whatever happened to a good old fashioned clutch pedal and a stick in the console?

Hmmmmm... I think it's wrong to be honest. I can't, and I don't think anyone can do a brake stand without pulling the brake fuse because of this safety feature.

I first noticed the behavior when trying to get into heavy traffic. I did a few tests earlier tonight and it appears that the brake override does not work at a standstill but you only have to be rolling for it to kick in. When standing still, it feels like the TC stalls (I even got a little wheel spin when releasing the brake); when moving, it feels like the throttle is being limited. But I may be misinterpreting what I'm feeling.

This makes more sense. I see no reason why the brake override would kick in while the vehicle is stopped, obviously, because its intent is to help stop a moving car. You're brake torquing, which is equivalent to us MT owners launching the car at a higher rpm. You can do this on any auto with the same outcome.

go to nissan.co.uk and see the specs of the Auto, they have three different packages the GT version is Auto over their. It lists the 0-60 slower than the sticks?

My car has a Stillen supercharger,UpRev tune on the motor/ trans and Aquamist meth injection kit on it so Nissan doesn't have number that represent my car.
