Some hydraulic clutch system problems Options

[eggman40]

i have personally rebuilt a c52, and they DO use synchros on all gears, like i suggested earlier, all those symptoms sound like a faulty clutch, and even though it may feel like its engaging and disengaging properly, it still will make the shifting notchy.

Do you think mine could be the cause of a faulty install on the cluth? Because it has no more than 1k miles on it of relatively easy driving. No track days yet.

Could it possibly be the throwout bearing?

When I let off the clutch pedal in neutral quickly something from my transmission area makes a clattering sort of noise...if I slowly ease my foot off of the pedal, this noise is still present, but is much quieter. I was told by a few people that this was my throwout bearing and was nothing to worry about, but could it be possibly be causing my problems?

I think now is the best time to replace that clutch. By the way Coomer, do you still have the tranny from the 7afe or able to get one that is good condition? I figure since the 2nd gear synchos are getting bad on your tranny, it would be best to replace the tranny and clutch all at the same time since your gonna have to get underneath the car.

I have a tranny from my parts car that I figure I'll use, as it's in better shape. I also plan on installing a very light flywheel when I replace my clutch/tranny.

But I'm really wondering what my problem is exactly.

Also, if I'm using an AT200 C52 tranny with a AE92/AE101 clutch disc and pressure plate, what throwout bearing do I need? I really don't want that annoying clattering noise or have anything fail on me.

OK, I just posted this topic on club4ag to see if anyone is familiar with doing this tranny swap and/or good information that could solve your problem. I even tried searching briefly online and I discovered that this problem is common with most c52 transmissions But I also did manage to find a link for another ae101 manual tranmission on ebay. If your interested, then check this link out (the seller even has his/her phone # listed for contact). Meanwhile, I'll keep you updated with what the guys are posting on club4ag.

Thanks...I already actually posted on Club4AG.

And there's no way I'd buy another C-series tranny...they're just not durable. If I end up eventually buying a new tranny, I'm pretty sure I'll get an E-series and somehow get it to work.

I tried changing the fluid to Pennzoil Synchromesh this weekend...didn't do a thing except waste $23. Looks like I'll be pulling the tranny in the spring when I finally have time.

When I switched to GM synchromesh fluid(which I think is same as penzoil), it took litteraly 1-2 weeks of daily driving to really improve. Don't ask me why..but after it was impossible to grind 2nd gear, that really amazed me...and 100 000 KM later it was still not grinding!

I came home for the weekend to pull the tranny out of the Celica and put in one that's in better shape. I was ready to start pulling the tranny, so I started the car up and figured I'd take it for one last drive around the area. Interestingly enough, the shifts were much smoother. So I took the car out to the canyon roads and actually enjoyed it for the first time in a while, since the shifts were smoother. Apparently the Pennzoil Synchromesh does work; It just takes it a while in my case (and yours Rayme.)

So for now, I'll hold off on swapping trannies until I pull the motor to do some work, hopefully over Christmas break.
