Thread: Clutch/Tranny Problem

Ok, here's the deal. The clutch doesn't engage or disengage properly. I have to force the tranny into gear while double clutching it. Sometimes it acts normally, sometimes I have to do this. It's not a constant thing.
Bleeding it helped a lot. But then it came back. I lost pedal pressure. But then sometimes it'll come back. There's a little bit of fluid under the boot where the rod meets the fork.
I also put the extended slave cyl rod in that jonathan made for me. Didn't help... So now I'm lost as to what I should do.

i think i figured it out. i'm going to check the relief valve when i get home. but keep the suggestions coming.

What clutch are you using?

What fluid were you using in your tranny?

Might have worn out synchros....

How many miles are on your tranny?

synchros are good. using an ACT2600. not sure what Jonathan put in as far as fluid goes. might be mobile 1.

100300miles on tranny.

i read something on RRE that described my exact problems, so i'm going to try the fix.

check your tranny bolts, i had to force my car into gear from here to yc, and then lee made me feel like and ass and asked me if all of my tranny bolts were tight.............hmm, guess what, one bolt was loose, tightened the crap out of it, then all the problems went away

those are good. OldDirty put them in.

so i went ahead and adjusted the top of the clutch and the rod (turned it counter clockwise to raise it up off the floor) and it feels great. but, i still have no pedal pressure.
apparently there is supposed to be a relief valve on the master cylinder somewhere. i don't know what the hell that is about, but they say it's on 2g's only.

this is from RRE:

2G Pedal "Pump Up"
If you are fighting an inconsistent pedal adjustment in a 2G, adjust the upper pedal stop adjuster so that you gain additional free play at the top of the pedal travel. If this is your problem, you will notice that the pedal suddenly gets very tight and the release point will suddenly move up a lot, this is the cause.


2Gs need free play at the top of the pedal travel. If it is close to no travel and right on the edge, then it pumps up. Only 2Gs have a relief valve in the master cylinder that needs to be uncovered so fluid can go back into the reservoir on the clutch release. If not, it gets tighter and tighter and tighter. Then it may slowly relieve the pressure and it is back to normal. Just a 2G thing. You need more free play at the top of the pedal travel.

that is my symptom right there. anybody know what they're talking about?

To fix that, you'll either need to adjust the master cylinder rod (screw in) so that the engagement point is farther away from the upper stop (cruise switch), or adjust the upper stop so that it's farther away from the floor (I did not have to do this).

If you really have no hydraulic pressure, check your master and slave cylinders. If you're not getting enough throw,and it sounds like you're not as you can't get the clutch to disengage, you have something else going on. Is this a new clutch and flywheel? If so, maybe the step height is an issue. If not, years ago I chased some disengagement problems until I found that a spring had popped out of a clutch disc.

i'm in the works of adjusting the rod and top stop. it seems to be helping, but i have to get it dialed in. i'm going to replace the master cylinder when i get some skrilla. this weekend i'll be draining the fluids out and filling it up again.
the clutch was new before the engine took a dump. the flywheel is BRAND new. i'm considering dropping the tranny and replacing the pivot ball and shimming it and putting in a new clutch fork.
