I'm having a very frustrating problem. Bseries EG Civic will not go into gear at high RPM. After I launch and go to shift into second gear the shifter feels like its locked out from going into 2nd gear, which prevents fast shifting. I can hit the clutch and wait for the rpm to drop while holding the shifter back and eventually it goes in. When you drive it around in the pits it shifts like a dream at lower rpm. I've had this problem for months! I've read and read and read and listened to a lot of advice from different people and nothing has fixed this issue. I replaced the CMC to an omni and then back to a new stock unit, replaced the slave cylinder, tried 3 clutches, 2 flywheels, took tranny down about 10 times, opened tranny and everything looks great, changed to a different transmission, and adjusted pedal, changed TO bearing, changed shift fork, shift linkage is new w/ oem shifter and have bled line correctly. I am running a 3an line from the CMC to the slave cylinder, not the oem line. I also noticed when putting in the new transmission that while trying to bolt on slave cylinder it does not push in when left connected to the line. We had to open the bleeder to release pressure. I will be changing back to an oem line as soon as I find one but I don't see how that'll make a difference. I also want to mention that I did have the car creeping on the line before and that's gone away in this process, dont know if that could be associated with the same problem. I need help, I just WANT TO RACE MY CAR!!!! Does anyone have any idea?

 

I had that problem a while ago..what clutch u running? My pressure plate had a problem where only half of it was releasing. Also have u adjusted your clutch pedal?

 

CC Iron Man and Yes multiple times. Doubt 3 different PPs had the same issue though.

 

To add, solid mounts and bushing are in as well.

 

Put the car in gear with clutch pushed in and rev engine to rev limit see if car moves.

 

Like I wrote ^^^ it does not creep anymore.

 

Well you changed everything,but the driver lol

 

Yes he did. 3 different drivers

 

I cant figure it out..... if somebody reputable wants the trans sent to them to look at pm me.

 

have u changed the shift forks ? They could be bent?

 

I don't think it's the driver...

 

Have you checked the shift change holder arm?

 

Does it only do it in 2nd, or all of the gears? Youre sure the synchros are good? Have you tried replacing them, just for good measure?

 

 

David-when I saw the trans apart and looked at gears/syncro I would change them out.
They look rough and that will prevent shifting at high rpm.

Which time. It's been apart about 5 times. I bought another tranny and put it in and it does the exact same thing. It should rule that out.

 

This was my problem a few years ago. Kept me out of 4th gear for over a year and a half.

 

I've had an shift change arm break and it feels just like it. But I've inspected its not bent or cracked.... sometimes the spot welds break but everything looks fine...

 

I have the exact same problem, only difference is I haven't changed all the parts you have and I just want to race too!! Keep me posted if you figure it out and I'll let you know what I do and see if anything helps

 

bump for an update

 

The creeping was propably a hydraulic issue. With everything you've changed my money is on 2nd(synchro, hub, sleeve) or broken throwout fork (bent or cracked where the pivot ball sits).

Changing trannies doesn't rule out the tranny when they all have 10-20 years of abuse on them. If you don't want to jump right into a tranny rebuild try and find a friend with a "known" good tranny willing to let you try.

 

Also, there is a point where the throwout travels too far and the clutch starts to re-engage (why they make pedal stops). To test this, temporarily adjust the clutch master rod in just enough that it engages the clutch more towards the floor(more free play). If that works play with it until you find a good spot or install a pedal stop. If it makes it worse then rule it out and adjust it back.

 

So does that mean you have changed to different brand PP's? or where they all CC? I ask because I was having the exact Issue on my h2b with stage 2 CC, smooth as hell at low RPM but as soon as I tried to do a redline shift it would not go in/grind. Changed everything out for a ACT unit after finding out some people on here had the same issues with CC and the problem went away, been great ever since.

 

Thanks for the input. We've actually tried this too though. Didnt help. We also changed out the shift fork. Didn't have anything wrong with but decided to since we've changed everything else.

 

Yes fidanza flywheel to cc flywheel and carbonetics to cm to cc and at one point we even put a cc twin disc in. So that makes 4 clutches.
