Any of you get a noisy ‘fairly loud’ clunk when shifting sometimes?

Happens up or down shifting.

Or does the 8 just have a noisy gear box.

I did not see (or missed) other posts on this matter.

Wait a second or two after a stop with the clutch depresed and the move into first gear. If there is no noise you have the same noise we all do. You do have a MT, rigth?

yeah mine cluncks sometimes when I throw it into first. ?

I've heard a clunk once in a while, but it seems like a normal mechanical noise... I wouldn't worry about it.

a clunk everytime i throw it into first... sometimes even while driving... i think the gearbox is just loud

Yes a MT and the clunk. 'for a better word' happens not just into first but between 3rd to 2nd or 2nd to 3rd or even 3-4 or 4-3
And not ever time, mostly it is fairly quit. All other MT I have ever used were very quiet and smooth to shift.

So maybe it's just a noisy mt on the Rx-8

The tranny on the 8 is less than admirable. It does perform well for me at higher RPM's.....but mine actually GRINDS going into second (mostly) when cold. Have been to the dealer many times with this issue, but (of course) they "cant seem to reproduce the concern"

I too have the clunk you refer to.....I believe it is normal.

I heard the same clunking before I got used to driving my car. You are probably reaming on your synchro mesh. Try double clutching. Also, when shifting you should match RPMs with the gear ratio to the one you are shifting from. Once I started doing this, the tranny works fine, no problems.

my gearbox clunks sometimes, it seems only when engaging 1st or reverse though.

I used to get the clunk. It seems to be the sync clutches or whatever. If I get the RPMs right it doesn't happen. I also always let the clutch out before putting it back in to shift into 1st.

The only clunk I get is when the car has been shut off, and I first start moving. Usually the first 10 feet of movement or so.

I have found that I have experienced less of all that is mentioned after changing the tranny and diff fluids to synthetics (I used Redline). It took a couple of hours after work. Do a search if interested. Plenty of DIY info on this site. Shifting is very smooth now, even when cold (or as cold as it gets this time of year in NC).

Here's a question that will show how inexperienced I am. Be gentle.

When rev-matching.... what rev matches which gear when shifting up? How about shifting down?

gsdev

The ratios should be on this forum somewhere. Here is an easy way to find out. Go to a speed in 1st gear, say 20 mph. Note your RPM. Shift to 2nd, make sure that you are going 20mph and check your RPM again then you have your ratio. You can do this for all gears. If you get it exactly right, you don't even need to use the clutch at all (not recommended.

the clunk upon rolling at first gear is the self abs check. Dunno about the shifting clunks though.

He shouldn't be checking out his abs while driving!
