[6pack] Clutch/transmission Issues

[Sally or Dick Taylor]

Darcy---There's not much left to check, after measuring the throw of the SC pushrod, checking the integrity of the fork pin, and the lack of movement of the crankshaft (thrust washers). The fact that everything was OK for the first 200 miles after the tranny/OD rebuild -should- eliminate the possibility of wrong parts being installed. But obviously something is wrong here, so I'd go back over all of the above.  Here's a few more (less likely causes of) things to check:

Air in the hydaulic system that shows up when things get hot.

Carpet? bunching that shortens the throw of the clutch pedal.

Wrong hole used at the clutch operating shaft. (Try the top hole in a pinch)

This same three-holed arm should be in a vertical position when at rest.

A missing internal spring in the SC.

You hould now be able to get the darn thing out in under two hours!

Subject: [6pack] Clutch/transmission Issues

Aggravating day on Saturday.  As an update, during the winter, I pulled my
transmission and had it rebuilt by John at Quantum Mechanics.  While he was
in there, he added an OD which I was very happy about.  Reinstalled and all
was very good for about 200 miles.  All the issues I had about grinding
during hard shifts were gone. Suddenly, shifting started to rapidly go
downhill.  Started by being difficult to shift from 3-4 and degrading to the
point where getting it into first or reverse was almost impossible.  On the
way home on Friday, I had to turn off the car and start it in first or
reverse since getting it into gear was impossible.  

So some investigation had me under the car and while my daughter pushed the
clutch, noted that I had about 5/8" of travel at the slave cylinder.  All
seemed fine there so the obvious answer was a clutch fork pin.  Ordered the
parts and pulled the transmission on Saturday.  Had the unit on the bench in
2 hours 15 minutes.  Very proud of myself until I investigated and found the
clutch fork pin to be OK.  Not Good!!  Then removed the pressure plate and
clutch disk looking for who knows what, all seemed OK.  Looking for great
insight.  Please help.
