M6 question about shifting

Dustinmaro · 10-30-2017, 06:18 PM

I have an 18 1LE with 600 miles on it. I have started to get on it some. I mean just to under 4k rpm and the tires spin and everything. But when I push clutch in to shift fast I hear a bump. Or feel it/hear it. I really don't think it's anything wrong with the car. I feel like I'm not using clutch right. Like it makes pump noise when pushing in during wheel spin and it grabs and then makes a thump? Does that sound common to you guys? Car sounds and was built amazing. No rear end noises.. So far...

Possible rear end noise. Don't forget to change the rear end fluid in a couple thousand miles.

I never hear any bump or thump no matter how hard I hit it.

Mine is noisy/clunky sounding too when I push the clutch pedal in in most circumstances. Was going to ask about this today as well. Haven't driven too many manuals in the past (Mustang Ecoboost and Audi A3), but this seems a lot noiser / more mechanical feeling than other clutches.

The shifter itself also seems to physically move and vibrate a lot, especially in higher gear. Not sure if this is normal, haven't seen other cars do it as much.

Ya I did some 0 to 70 stuff today after I drove for 5 miles and ya it's making a thump or bump noise when your grabbing gears. I hear it behind me but it happens only when I release the clutch pedal to slow and rpms drop. And it's picking up. Think in my ls1 the Rpms hang longer . Either way the rear end getting fluids changed on Friday. Is yours also an 18?

I'm almost to 500 miles on my '18 SS. Once I'm a bit over 500, I'm letting her loose!

Mine does the same noise, I figured its the traction control taking over. Try it with everything full off such ass traction and stability, not just stabilitrak mode, solved my issue, now the rear spins and doesn't make that clunk or bang. This is at full throttle and shifting at redline of course.

Dustinmaro · 11-01-2017, 09:43 AM

Ok ya I will try that. I mean that car runs and drives amazing. It's just that bump that bothers. If any one else can think of anything else let me know plz

I'm hearing noise from pressing the clutch in itself, before I even move the shifter. It's noise coming from the transmission and not the rear end.

Mine has that as well, my guess has been it's the drive train engaging/disengaging.

Mine also does it. Changed the rear fluid at 1500 and it still does it.

I don't understand the "Bump" you speaketh of.
