hey everyone
I bought a used 2011' g37s mt with only 1,230 miles on it. I've been driving the car normal not abusing it . its my weekend car btw i shift around 3k-4k rpm depending on my driving mood. its been 6 months since i had the car, i've put 7k miles on it. mainly highway miles on it. my question about the clutch is if its normal for my car to rattle after letting go of my clutch in 1st ? and once i reach 3500k rpm i shift to 2nd and you can hear the gear going in ..is that normal? you can only hear it go in in 2nd gear not 3,4,5,6.

i don't know about rattle in 1st but i can hear the gear going in when i shift to 2nd. 1st to 2nd shift is a little harsh in our cars.
if you don't mind how much did you pay for your car?
Thanks

the car was $39,345 plus 3m paint protection $995, plus "warrant solutions" $2,300, plus sale tax $3,053, total was around $45,748 doesn't include the finance charge, which is $5,483 for $30,800 5.55% interest rate, i gave $15,000 down thats why it was $30,800 so in the long run total came out to be around 36k

yea the rattle is making me think something is wrong with the clutch but i mean i dont abuse the clutch maybe at first when i got the car yes a little since i had to get use to the clutch and i agree with you going into 2nd gear was making me mad, i thought i was messing up the car or wasn't driving it right.

I know there's a rattle (marbles in a can type noise) when you're idling with the clutch fully engaged (pedal completely off the floor). This noise goes away if you fully depress the pedal to the floor. Completely normal and common on many manual cars.
If you're getting some sort of clanking noise when shifting, first make sure you're shifting correctly. There is a huge gear ratio between 1st and second gear. If you rev up to say 3K rpm in 1st, you need to let the rpms drop to about 1700 before letting the clutch back in in second for a smooth shift. Otherwise, you may hear what sounds like clanking as the clutch/engine are fighting to match the rpms.
Also, likely because of this huge gear ratio difference, if you try shifting fast from 1st to 2nd, you may feel a sort of vibration, AND hear some sort of clanking noise. I believe this because of the abrupt clutch disengagement.
The smoothest shift occurs when the trans is unloaded. That is, the car is not accelerating or decelerating.
Try this;
Accelerate as you normally do in first. As you're getting ready to shift, try easing up on the throttle just before you disengage the clutch. Perform your shift (keeping in mind the rpm difference), apply slight throttle before re-engaging the clutch.
Reading the above will take 10x longer than to actually do it, but it's a matter of timing. So long as I remember to apply this, 9/10 times, 1-2 shift is just as smooth as all the other gears.

Yeah, now that my clutch is pretty much done for, I've been looking for a good flywheel and clutch. I looked for better throw out bearings, but couldn't find anything. I'm thinking about staying OEM and getting a factory flywheel and an aftermarket clutch, at least I'll get some improvement without the added noise, right?

Adjust how you shift, either lower RPM or higher. You won't get the clanking. I used to but I changed that shift and haven't caused it since.

At what rpm do u guys shift at? I usually shift at 2100-2500 but then again, i do love to push it alittle lol. It could also be because your car is still a baby because mine felt wayy stiffer when i first got it and now feels more softer and even though theres still clankiness from 1st to second, its less
