Hey guys, does anyone with a 2002 S2000 also experience an occasional 2nd gear grind when shifting from 1st into 2nd? My transmission has done it from the day I bought it, but i'm afraid to let the grease monkeys at my dealership touch it already. I toured their service bay and I must swear that I don't think there was a single guy over 18-20 years old working back there. I don't know exactly how to reproduce the grind, but it just does it occasionally. Every other gear engages butter smooth, except when upshifting into 2nd. I have 575 miles on it now.................

What's causing this intermiitent grind? The S2000 that I test drove(Sebring Silver) had an amazingly butter smooth transmission that felt incredibly detatched and smooth! However, it was sold to another customer and the dealership let me take it for a quick spin.

 

My '02 had the 1-2 grind. I swore it was the car, not me. Then I moved my seat forward one notch. End of grind.
It's a hydraulic clutch, so it needs to be to the floor to work.

 

My clutch pedal is completely to the floor when I shift. I have tried taking every bit of human error out, but it still seems to do it occasionally. Something I have noticed, is that the faster I slam the shifter into 2nd gear, the less likely it is to grind it going into 2nd. If i've been idling at a light for a while, or i'm facing uphill, it will also slightly grind 1st gear going in from neutral as well.

 

I had that since day one on my MY2001 as well, but I think that I got rid of that problem today. I changed the transmission fluid to GM Syncromesh Transmission Fluid and what a difference it made. This stuff is just fantastic! I don't think that I will have any more problems with second gear grinding any more. I have always had a pretty notchy feeling going into second gear with my transmission, but not any more! Now it's just as smooth as anything that I have ever felt.

 

Out of curiosity, where did you purchase it? I imagine i'll only need 2 quarts at most, right?

 

Here's a link with the info: https://www.s2ki.com/forums/showthread.php?...&threadid=77220

The transmission takes 1.6 quarts to fill it according to the manual.

my 2002 with 4000 miles grinds here and there but its only when i shift quickly from 1st to 2nd and if the rpms are above 7k its really gettuing anoying because i get scared to shift fast because i dotn wanna break anything and the dealer told me theres no prblems with it

 

My '01 does the same thing. My dealer is un willing to do anything about it until I can reproduce the problem for them.

 

i guess its wroth a try to switch tranny fluid to the GM synchromesh stuff but is it to early to change i have 4k miles only

 

I had the same problem and also solved it by moving the seat one notch further forward. If you let the pedal off the floor at all before shifting into 2nd and you are shifting fast it will grind. The 1 to 2 shift is the quickest most direct shift you make. At first I swore it was the car but then I paid close attention to the clutch and realized I was inducing it. Moving the seat forward solved the problem.
