Hey guys, first I want to say I'm excited to finally be part of S2000 club! Woot!!
Just picked up a 2006 s2000 red.
That being said, I've been experiencing notchy shifter (so I re-greased it) and thump noise shifting to 1st or 2nd gear from neutral while parked... But the thumping noise doesn't happen if I press the clutch and wait 2-3 seconds before shifting to 1st gear... So I did a lot of research on my own across various forums including s2ki and I'm getting the feeling that this is normal for S2000...
Would you agree or should I be worried?

Thanks!

I have only owned my s for a couple months , I had this when I picked it up and still have it , I've put it down to a heavy clutch meant to be driven harder haha , if your giving it some welly the transition is smooth as ever , just in slow traffic and that mine clunks about

New mtf will help with that for awhile, but it's normal. Shifting at around 5 grand will help a lot.

I bring mine up to about 4-5k and hold it there for just a second and right before shifting give the throttle a tiny blip. Seems to smooth it out a bunch.

The thump noise is perfectly normal and caused by a situation present in all manual transmission cars. When the tranny is in neutral and the clutch is engaged, the input to the tranny is spinning at the engine rpm.

When you press the clutch, the input continues to spin for a bit and when you engage the gear, it connects to the stationary rear wheels through the drive shaft, differential and half shafts and there is mechanical backlash in that drivetrain.

When you engage the gear, it stops the tranny input spinning and takes up that lash. That is what makes the clunk. It is just more obvious in the S2000 than in most other manual tranny cars. The level of clunk can be louder or softer depending upon the condition of your drivetrain.

When you disengage the clutch for several seconds before engaging the gear, it allows he tranny input to spin down to a stop or at least slow enough that you don't notice or feel a thump.

Make sense?

Yup makes perfect sense! Thanks everyone!

Also, just to add extra, Mine stopped thumping when I started shifting a bit slower and smoother. I was banging my shifter before, trying to shift as fast as possible. Smooth shift, no thumping.

That's for me at least
