My Transmission Grinds sometimes when shifting from 1st-2nd at the Highest RPM's
My Transmission sometimes Grinds (very briefly) when shifting from 1st-2nd at the Highest RPM's. It is a very small and short grind and it will only do it when shifting at very high rpm's into 2nd. I am experienced at driving a 6-Speed CL as i have had one before this, and i always have the clutch fully pressed down. My older 6-Speed did not do this and these cars are designed to be able to red line without a problem. My Clutch is the original and my RPM's act normal when the clutch is engaged. My car only has 53,000 Original miles on it and it's previous original owner was a Man in his 50's. Has this 1st-2nd high RPM grind been solved before without replacing a 2nd Gear Syncro and clutch? Could it just need new Transmission or Clutch fluid?

Try to flush it out with some GM syncromesh fluid.. I heard that the syncromesh is the SHIT for MT cars..alot of the 3G tl people use it.. Im not sure how you drian/fill the fluid in a manual trans car but in auto u gotta drainn 3 and fill 3 and dive for 10 min through all the gears and reapeat 2 or 3 more times to get ALL the fluid out..
Didn't u total a manual CL not too long ago?
You have anouther 6 speed tranny laying around swap it out!

Ooops, yup looks like you lost pressure plate springs. You will be grinding gears and have it slip. Does it depress a bit easier than usual? I know it is hard to say with hydraulic clutch but did you fell any changes in pedal effort?

Maybe alittle bit easier to press. It was slipping for about 20 minutes then it went back to normal again. When it was slipping my RPM's went up about 500 each time i pressed down the clutch to shift. Wouldn't a bad clutch be the cause of my 2nd gear to grind at high shifting?

Yup! I just drove my car again and now i am POSITIVE it's ONLY my clutch. My Syncros are all fine because I purposely just tried to shift into second without using the clutch (I rev matched insted) and it went into 2nd gear without a problem. This proves that i just need a new clutch for my 6-Speed.

Rev matching will actually not verify if your sychronizers are fine or not, this technique is popularly used in semi trucks. These transmissions do not have any synchronizers at all!!! You change your gears without the clutch - just rev match..... but still I think you got the problem with your clutch

You missunderstood what I just wrote - semi trucks still do not have synchronizers at all!!! and rev matching does not verify condition of your synchros. When you match speed of transmission gears no synchros are needed, its plain simple! BTW I do it for living,Volvo 770 500hp semi, 13 speed EatonFuller transmission - unsynchronized

Yeah, but my last 6-Speed CL NEVER grinded 2nd. And the one i have now didn't start grinding 2nd until 2 weeks ago, now i am noticing my clutch is bad (the clutch never felt like it had been engaging correctly compared to my old CL, which happened to have a new clutch). Wouldn't you suspect the 2 week old 2nd gear grind on my car to be related to my clutch?

Mine seems to do that too, but only when cold at LOW RPM? Anyway being as it only happens when cold during the 1st mile I haven't worried about it.
Does sound more like the clutch in your case. It's dragging, not fully disengaging. I have 122K miles on my car and the clutch still grabs hard. And I drive hard too. I can tell it doesn't bite as hard as when I got it but it's got at least two years left in it. The guy you got it from must have been using it hard or riding the clutch for it to be shot @ 53K miles?
So does someone have a spare 6spd trans on here? I maybe interested as a spare?
