Is the issue worse with the trans hot or cold? If it gets better with trans
oil temp, it's probably related to running a too-thick oil or the wrong
additives. If not it could be clutch drag. Two easy ways to check clutch
drag:- 1. Jack the driven wheels off the ground, select 1st gear and hold
the clutch in, the wheels shouldn't rotate and you should be able to lift
your foot about an inch at least off the floor before they start to turn. 2.
Engage a gear (clutch depressed) and then carefully, slowly partially
disengage it (so the synchro teeth are just lightly touching) there
shouldn't be any clash or grinding until you lift your foot at least an inch
(or use a non-synchro gear (better)). Be gentle though as hard grinding
will damage the synchro teeth and your shifts will degrade markedly due to
pointing damage. Note that the "bite" point you feel is at a higher pedal
position than true clutch "spin-free" by about 1/2 to 1 inch typically, sop
this allowance needs to be made or you'll wear out your synchros quickly and
have hard shifts as well.

Have you check the clutch's reservoir to be full of brake fluid, as

Ok, guys.....I changed the tranny fluid to Amsoil 2000. No noticeable
change. The shifting still is hard whether the engine is hot or cold.
Checked the clutch fluid, and it's filled 3/4 full. The friction point
is near mid stroke. So I'm assuming the clutch is fine. Jacked the
rear and selected first gear...disengaged the clutch and the wheels
rotated slightly which stopped after quick engine rev. After playing
with it for a while I determined that the dragging clutch seems to be
intermittent. This weekend I think I'll bleed the hydo line. Although
I feel that air in the line should not be intermittent.

If the master or slave cylinder were bad and was introducing air into
the system, wouldn't there be fluid leaking??

Again thanks so much for all the advice

I have no idea on the specs of the snake oil you put in there, but it
calls for a low sulfur gear oil, a GL3 I believe someone said, but GL4
is called for.

Same deal for the friction base. If the snake oil is made for
differentials, it usually will have the limited slip additive and say
something like it's safe for traction devices. This will 'not' work.

When I got the correct fluid in mine, it took a little while for the
shifting to come back.
