Loud bang when shifting from first
 

Wasn't sure where to put this but I get a loud bang on the firewall or front under carriage when shifting from first to second at high rpms. It sounds like someone is punching my firewall. I know the 370z is noisy but is this normal?

2014 with 1500 miles, thanks.

manual or auto?

Sorry manual

Dealer time!

It only occurs when I'm driving aggressively like actually getting on it. Still not normal?

Tell them to check engine mounts.

That's what it sounds like to me too I just know the drive train in this car tends to be noisy.

When you shift. Are you side stepping the clutch pedal?

What do you mean

Need to get on it as you hit the clutch.. I noticed this too.. Just figured out how to hit the gas and when to hit the clutch at the right time.. I dont get the noise anymore.. Hard to explain

Are you sure you're pushing the clutch in all the way before shifting to 2nd? Maybe you're shifting gears mid way into your clutch. This can create a thud from your transmission. Your engagement from 1st gear to 2nd gear is probably out of sync when you're driving aggressively.

Take it easy and slow it down. Gas pedal off, press clutch all the way in, then shift.

That's when you push the clutch pedal to the floor, and then slip your foot to the side. The clutch pedal comes back up with a bang, because it's bouncing off of the stop.

:iagree:

Unfortunately not the case, sure does seem like a motor mount issue.

We used to check motor mounts by putting the engine under a load and then no load while someone watched the engine and mounts. If it moved more than usual, it was usually a mount. If you got "lucky" you could see the mount separate. Not sure if this would work with a modern car, but it should.
