Does anyone's transmission clunk from time to time when pushing the clutch in??

I have an '10 370 and from time to time when I shift from first to second or when I take it out of gear from first you hear a loud thump come from the transmission or clutch...has anyone else had this problem? is this common with the 370 to make that sound?

Something just doesn't seem right with that lol...

Yep, it's normal.

m4a1mustang · 04-08-2010, 08:20 AM

Totally normal.

Sharif@Forged · 04-08-2010, 09:06 AM

Normal. The 350z/370z has always been a fairly involved and noisy car. She'll make some odd noises from time to time. Nothing to worry about.

Try this: When shifting from 1st to 2nd, push the clutch in slowly and don't shift immediately. Then slowly put it in 2nd gear. I'll be willing to bet there is no noise at all.

Ya there's no noise when you do that...it's mostly when the motor is reving up on a shift and then you push the clutch in....sounds like a knocking sound...Well I'm glad to hear it's normally, I was going to take it into Nissan...

Yup, I get that.

shoopajae10 · 04-08-2010, 03:24 PM

yes, i found out that if you depress the clutch slowly and smoothly you will not hear the thumping dumping pumping flamming noise.

chitown1863 · 04-09-2010, 09:43 AM

Does anyone know what causes that? What's knocking when you depress the clutch?

Red370 · 04-09-2010, 01:03 PM

sounds like the clutch disengagement from the flywheel.

Give it like 2/10ths of a second longer off the gas before pushing in the clutch. This really only happens from 1st to 2nd and it's like the engine is still accelerating even with your foot off the gas. Might have something to do with drive-by-wire.

damn... i was also wondering why would it make that weird sound.... i thought my driving skill sux bad... lol thanx God that it is normal sound
