I have a 05 s2k, i got it pre owned honda certified. When i press the clush and engage 1st gear i have a clunking noice and the car tries to move fwd for a split second. To my understanding this is not normal...I took it to the honda dealer and they said it was normal on the S2k's... I cant belive that and i want some opinions because is just not right.... and if there is someone that has the same pronlem please talk 2 me....Thanks

 

Definitely not normal. At least mine doesn't do it.

On the bright side, it sounds like a clutch issue, rather than an actual gearbox issue.

Dealers continue to amaze me.

 

i agree that isn't normal. i have to give a little more effort sometimes more then others to get mine into first but i know what the problem is with that. but with your car trying to pull forward it does sound like a clutch issue. how many miles are on the car? any recent clutch replacement? you could just need to bleed the system air can be in there not compressing the slave all of the way or the fluid could be bad from water getting in which could mean you have a line with a pin hole in it. try bleeding it first and if your problem is still there post back up

 

Clunk is Normal if you engage the first gear to fast. Basically hold your foot down for couple second longer then put it in to the first gear. No clunk. Car is small and stiff, you can feel everything and I was worried as well and brought it back to the dealer. Now I know it's normal.

Now I don't know if you are over exadurating, but if it REALLY does jerk forward, you have a problem.

 

I vote bleed clutch!

The inertia of the spinning gears in the tranny shouldn't have the ability to move the car, especially coming off of idle, as is normally the case when switching into first.

 

The clunk is normal. There have been many threads about it. It's kind of annoying, but it doesn't seem like it ever leads to any problems.

 

Thanks everyone, and for the guys that said it was normal...actually the technician that took the car for a ride with me told me about the holding the clutch for 2secs and then trowing 1st and the clunk was gone...so he was very confident to tell me that it is a normal problem on the s2k, but u know such a price car ...come on....Some were in me i still think is not a normal thing....If i buy a Ferrari and it does that , ill return the thing lol...

 

They wont take it back

They will suggest buying another one though just in case other one REALLY does die on you.

 

Not true - the clunk is caused by jamming the transmission into first before the disk and input shaft have had time to slow down.
The first gear syncro has to synchronize the disc and input shaft (slow it down) from idle speed (850-1000RPM) to zero RPM. If that's done too quickly (by instantly jamming it into gear) - you get the clunk and there's enough inertia in the disc and input shaft to bump the car forward in this situation.
If you don't think there's enough inertia - take a 8lb disc splined to a 12lb shaft and spin it to around 850-1000 RPM and try and stop it instantaneously - noise will insue. It's not unlike taking a table saw blade and trying to stop it immediately after you shut the motor off. It'll rip your hands off.

Solution: What the tech said: give the transmission about two seconds after you push in the clutch before you put it into first - and do it more smoothly.

FTR - there's not a front engine/rear drive car built that won't do this. Most Ferrari's are rear engine/rear drive, but the ones that are FERD do it as well.

 

Exactly what I was trying to say, only I FAILED at it since there was no reasonable explanation behind it. hahaha

Can some one sticky what he said?
