[6pack] Transmission or clutch issues

[brian at asmoothmove.biz]

It certainly sounds like the clutch not fully disengaging for a possible number of reasons. The symptom may not appear when cold as the transmission oil is “thick” enough to resist the first motion (input) shaft’s rotation.  When things warm up as the transmission oil “thins out” and can no longer resist this rotation. Unfortunately I can’t help with a specific cause. What is the size of your slave cylinder? Some are have a large dia. than others I believe.

Here is my problem which I need some guidance.  When I start in the morning everything works fine.  I can put the car in reverse without any problems.  I can up or down shift easily.  As things warm up, it gets harder and harder to shift gears.  It is almost like the clutch is not going far enough especially into first or second.  Even when I double clutch it.  When I try to put it in reverse, it grinds.   I can get it into reverse but it does not want to go there.  If I turn off the engine and start up with the clutch depressed, it will work without grinding.

I made sure I had the DOT 5 fluid up to full.  I got an adjustable link connector between the slave and clutch and have lengthened that out quite a bit without success.  Transmission oil was low, so I filled that. 

What do you think?  My regular mechanic thinks it is the clutch, but why does it work when cold?  HELP!
