Regreased the shifter, the notchy grab has been reduced by maybe 80%. I'm going to try and attempt to do the tranny and clutch tomorrow and between the two I'm sure that the problem will be solved.




I was doing some reading awhile back about when cruising at a very slow speed (1-4 mph) and changing gears, there is a slam noise coming from the rear of the car. Anybody have any idea what could be going on with that? I'm overdue for a diff fluid change now, Honda didn't have any washers to replace in stock but they get here Tuesday. So that will be changed next weekend. Could that be the culprit?

You are off to a good start by getting that much reduction from one adjustment, if you do the other stuff you should be pretty happy.

I recommend you check underdash at the clutch rod to make sure there isn't any fluid leaking, good to check at that mileage to be sure. Checking the clutch rod clearance is another good thing to check as it affects the timing of your shifts and can lead to smoother shifting if the clearance is currently too large.

That noise you refer to is coming from the transmission, it is pretty normal for the circumstances you describe. Are you upshifting at those speeds or downshifting ?. This tranny works best at higher rpm shifts. If the noise happens when downshifting you can reduce it by doing a double clutch procedure and giving the gas pedal a good stab while doing the double clutch.

This is the same noise as when you're sitting there idling in neutral with the clutch up. Then you put it into first fairly quickly and get a clunk. It's the same thing. Explanations for this has been given ad nauseum. Won't repeat it here.

I had same problem shifting into the 2nd gear. I changed transmission oil and no more problem.

It stormed and poured all day yesterday, hoping to get the rest of the work done in the week.

Appreciate the comments guys

Let me know how that regrease goes, I've changed my master/slave, bled with DOT4 ATE SB, as well as fresh MTF II and I still have these problems. I have not, however, done the regresed shifter.

Could also be rusted spline on transmission input shaft not allowing clutch disk to slide properly and causing notchy shifts. Mine was notchy due to this and eventually lead me to have to rebuild my transmission. When you reassemble the clutch make sure to clean and regrease (with super high temp urea grease) input spline of the transmission that the clutch disk rides on so that it slides freely back and forth on it.

I hope this isn't what I have. I don't think it is though, same for OP. In theory this would make all gear shifts crunchy correct? I have 101000 miles on the original clutch.

The input shaft splines on ALL S2000 trannies are rusted. I took mine out at around 30K and it was badly rusted. It's normal and not normally a problem. Only in severe cases would this rust create a problem. The clutch is one of the most operator used parts on this car. The rust gets scraped off in places that can become a problem. It can contribute to a problem but only in extreme cases would it cause a problem.

Well... I know mine are not
Because I took the time to clean and regrease them during a clutch installation - as mentioned in the manual.
Actually, not long before that the disk and PP were changed by a Honda dealer, we're talking 2005 IIRC.
After that I was not impressed by the way it shifted.
Simply becuase they did not follow the manual.
Up until today (2013 ) my shifts are smooth.

Sure, the disk only has to be able to move a little bit to break free from the FW during shifts.
The easier the better though.

IMO, things to have to get smooth shifts are:
#1 - clutch hydraulics - including push rod and pedal play - have to be 100% and without trapped air.
#2 - shifting technique.
#2 - no rusted splines.
#3 - good oil and greased shifter.

Yes, I used #2 twice, as in: equally important.
