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!

 

UPDATE: My Clutch is now slipping. I think this is why im grinding 2nd....

 

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?

 

It might be, it actually may not fully disengage - thats why you may have grinds

 

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

 

Ummm............ you are miserably wrong. ALL cars made after 1940 have syncros. .

 

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

 

oh woops sorry my bad I thought you were talking about cars, not semi's. I KNOW that no syncros are needed when rev matching, i rev matched it so I could compare it to driving with the clutch in as well. When i had the clutch in it would grind. This proves that it's ONLY my clutch, because the chances of a syncro going out coincidentally at the same time as my clutch are 1 to 1,000,000.

 

If it's slipping then yeah clutch. BUT....
For the 1st issue of slight grind going into 2nd at high rpm, that's normal. Both my 6MT CL's did it. It doesn't do it all the time, but occasionally my car will grind a little going to 2nd gear at redline RPM.

 

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?

 

just start with one thing at a time, if you need a new clutch get one.
- flush fluids, etc. .

 

Happened to me every now and then as well.

 

Yes, but the difference is it happens to me CONSTANTLY.

 

UPDATE: Took my car to the Acura Dealer, drove it with the Service Adviser, and he concluded that my Clutch is shot. He said my transmission is fine though.

 

happens to me as well. i didnt know what was going on so i just chocked it up to me being a shitty shifter

 

Was it you who totaled the 6-Speed Swap TL or was it someone else?

 

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?

 

Mine does it on occasion as well.

 

I get the 1st to 2nd grind at high RPM as well...almost like the famous 2nd to 3rd issue

 

Agreed. I sometimes get that little grind going into second at high rpms as well.

That was Ls TL I believe.
