I have been having the most persistant problem with my car. JDM B18c5 w/ S80 4.785 FD. Now before i go spending the money to purchase a 3rd & 4th Sleeve set. Is it possible for any of these cylinders to fail without visible leakage. Is it possible the hydraulic fluid could have lost its viscosity? Just like an oil? My shifts fine regular cruising rpms, no scratching or notching. After my first pass on the 1/4, The gears seem hard to go in.. and you have to wait on it, if you try to shift it too fast in the higher rpms it just blocks you. I just want to verify the problem before i purchase the wrong thing. Thanks.

 

Yep. I've had an OEM CSC and a prototype Omnipower CMC fail without visible leaks. What trans fluid are you running and when was it last changed? When was the clutch system last bled?

 

10 30w Engine Oil.. Shell. I can't ever remember my mechanic bleeding it before but do these things need bleeding ever so often? As i said in previous post it doesn't feel irregular on cruising rpms. It also feels fine for 1-2 passes on the 1/4. By the third it feel nearly impossible to find a gear in a regular timed shift, not forcing or power shifting. Its as if it takes its own sweet time to select the gear, that the only way it goes in. The Clutch doesn't seem to be slipping either. CC stage 3 = Carbon/Kevlar full disc.

 

You will definitely know when you have air in your clutch lines. Really low engagement(how far off the floor does the clutch engage?)

COuld be the clutch disc is sticking to the mainshaft or the flywheel.

 

It Sometimes feels as if it fluctuates.. but i can say it isn't considerably low.. I guess i will take a shot at bleeding it when installing the steel braided clutch line and see if it feels any better. I think it will end up being a Hub and Sleeve being the problem tho.

 

had the same issue

 

this is interesting info.....my gf car is having probs again with one of these items....check this post i revived....

i know i should have revived it here in the tranny/drivetrain section. I just would not have thought that a year after replacing both items one of them would be going bad already.

 

I have similar issue in 98 JDM Integra Type R, 1.8DOHC Vtec, S80 LSD. Already replaced Honda MTF but no good. Gears are smooth as butter with the engine cold (I've checked all Gears, 1st, 2nd, 3rd, 4th, 5th and even Reverse) but when operating temp is reached it gets more n more difficult to shift into all gears. The shifter takes more effort to put it into gear. There is no grinding, no squealing at all. By the way with engine hot, even if I shut the engine try to shift it is still hard to shift. This I believe rules out issue with pilot bearing or clutch, has to be something in linkage cuz with engine off n trying to shift gears the crankshaft isn't turning shouldn't be hard to shift. I suspect some swollen rubber bushing or i don't know. Please help

 

The bad thing about your problem Killer4sho is that it could be many things? When did you develop the problem? After clutch change or after gear oil change? I'll tell you this, a lot of people use CC clutches. There were a few threads on here about high rpm lockout with them. I'm on my third cc in about 3 years. I'm on a stage 5 now and had two stage 4s. None of them ever slipped, but I had high rpm lockout with the first one. Bad synchro springs can also cause the gear not to slow down enough that you can race change cleanly.

The only real way to analyze your exact problem is to start buying/trying different things. I know a guy that had high rpm lockout with cc and he welded a nut and bolt onto his slave cylinder rod so he could manually lengthen his clutch throw, that worked for him. With his setup it was like the clutch wasn't fully releasing the flywheel and allowing the shift. After the mod with the same cc stage 4, he went from high rpm lockout to shifting like butter.

 

Rob, I have the same problem on my 93 DelSol. What fixed it?
