7AT and cruising to a stop
 
Do you guys feel a "rubberband effect" when coasting to a stop? Hard to explain in technical terms but the car just doesn't seem to cruise smoothly. The car seems to engine brake very noticeably hard when the 7AT is downshifting(in D mode.)

Don't know if this is a sportscar thing(although my last car was a 00 Z28) but it's getting on my nerves in bumper to bumper traffic.

Yep, I feel it frequently - even coasting with light braking prior to making a turn.

Downshifts are definitely not smooth.

kannibul 09-23-2009 08:14 PM

I've not noticed anything.

Then again, I'm generally either acellerating, maintaining or braking. No coasting... :)

It's just the car shifting...nothing to really worry about.

Pretty standard with a lot of cars I've driven.

To look on an upside, at least the Z is letting you know its there. Nothing worse than a car you can't feel. :D

I've noticed that it's more prominent in foreign cars than american cars. At lease that's my experience. Doesn't really bother me either way...

Usually big engine,with big C.C.will have higher engine braking than 4 cyls engine.

awesomez 09-24-2009 09:30 AM

Yep I notice it, not every time though. It's normal. It's a little worse in 370Z than in most other cars I have driven.

dszombiex 09-24-2009 09:53 AM

It generally happens when the car downshifts from 4rth gear to 3rd. I dunno why 3rd engine brakes so much.

chief_Roka 09-26-2009 11:06 AM

If I remember correctly from my four 1 hour test driives... lol its like the car stops itself harder than u do during deceleration? If that's wat u mean? I think its normal. It felt like the engine was braking as u were braking with the car. I thought it was cool n made the car feel like to have the behaviors of a manual. :)
I'm sure there are owners out there who put thousands of miles on the car who may corect me if I'm wrong? But from my app 250miles of experience... lol. That's what I got from the test drives.

The 6 speed auto in my Mini does it too and the trans is Japanese...

kenchan 09-26-2009 07:26 PM

give it a tad bit of throttle when it engages the lower gear.

same thing on the synchro-rev match on the MT's when letting the machine rev-match
on the downshifts. unless you're braking hard the gearbox bounces you around because
there's no throttle.

billydsz 09-26-2009 08:42 PM

I've noticed it and I love it. If you're coasting you're probably stopping or slowing down anyway. It's just doing what you want it to do. The Z reads the drivers mind lol. Seriously though if you want to maintain speed in a coast put it in neutral or give it a little gas. Higher HP engines will brake more than regular car engines.
