What does "Zero free play" mean? The rod should be at its extreme end? We are talking about the rod that goes into the master cylinder right?
I've adjusted mine so that the end facing the driver is flush with the threads on the clutch pedal... Seemed to help, but not elimnate the problem.... I tried adjusting it a little at bit, but it made no difference till I got to the end and couldn't turn the rod any more...
Thanks!

This is the biggest misconception people make. They think if theres any pressure at all on the master in the released position, the TO bearing would be slightly activated. This is not true at all.
You would have to turn the rod far enough to get the master piston to move beyond the supply hole in the resovior.
Set it at zero freeplay, then move on to things like possible air in the system, or trans fluid.

The freeplay is in the hydraulics. When you push the pedal that first inch or two, fluid will squirt up into the master through the pin hole. This hole is the fluid supply hole, but it is also set in such a position to relieve all pressure when the pedal is fully released.

That brings to an interesting question... Could the problem be that the rod is adjusted so far into the master cylinder that the piston never pulls back enough to suck in enough clutch fluid thru' the pinhole to fully disengage the clutch? I can't imagine it's "right" to have to adjust the pushrod to its extreme end. I would imagine the piston in the master cylinder more like a one-way valve where clutch fluid can flow around it but... I don't know. Just throwing in my thought.

Well.... I got word back from the mechanic. They didn't find anything wrong. But, hey they want $1600 to open up the transmission and check! (plus lube some spline)...
Is it really $1600 to drop the tranny? Gee whiz...

[QUOTE=xviper,Jan 27 2006, 01:53 PM] I and others have cautioned readers in the past on adjusting the clutch pedal ONLY as a last resort and ONLY if the operator understands what they are doing.

Hi Xviper,
Yes, they were able to get it into gear no problem... When I picked it up it was working fine!
The clutch rod is still set to the extreme end. The only thing I did different is drive it on the freeway. Before when I was doing all my testing (after the fluid change, and the the clutch rod) I was only driving around town. Never go into v-tech and never went about 45.
After driving with the clutch rod "adjusted" and new fluid on the freeway all of a sudden everything is fine!?!? WTF?!?!
AS I stated in the first post I've had this problem almost 100% of the time for >month. How can it suddenly go away?
Stuff like this always happens to me... I tore my knee once, couldn't walk on it for a month. Go to the doctor its fine!... Then a week later I go to sit on the toilet and it gives out... The gods are working against me!

You might want to see if you can put that rod back to the way it was in small stages.
Having "found nothing wrong" and now that the car works fine, there is no Earthly reason to tear the tranny apart.
