[Shotimes] MTX shifting difficulty hypothesis

[Justin Schick]

Clutch engagement point seems good, but I couldn't do 1 or 3 nicely
without raising the RPMs. Ditto on the like butter while moving or
coming to a stop at 5 mph.

My 94 does almost exactly the same thing. Gears are still spinning at a

stop and almost impossible to engage first.  But mine is inconsistent
as 
h***l.
 A local tranny expert or two labled mine "disk drag".


I found three spin-down tests in Helms that go like this;

1) Release clutch in neutral, depress, wait 20 seconds, should go in 
reverse O.K.
2) Ditto the above, but put shifter "halfway" into reverse.. Slow...ly

release clutch and note how many inches off floor gears begin to spin.

There should be some 2 inches "safety release margin"
3) After put in reverse, remove to neutral, wait few seconds, try to
put 
back in reverse. Should be OK

My old 89 passed all 3 of these for 10 years and 200k miles on the same

Ford replaced second design, small dia clutch.
My newer 94 has a centerforce that worked fine before the tranny 
replacement. After adding the known good shifting tranny, it does does

this.

But it shifts like butter while moving, or if I put into first at 5
mph. 
First gear balking is inconsistent, sometimes good, others bad. 
Inconsistently flunks test 1 or 3 above. Some temperature correlation.

Very light pedal. No noise.

Current hypothesis(es): Good throwout bearing & cable, (wrong symptoms)

Warped / bent clutch disk, tight disc fit on input shaft,  or warped 
pressure plate cover from incorrect bolt torquing. Possibly bad 
fingers;  but no noise???
 
Anyone else got any ideas?
To help me confirm what to buy before I tear it apart?
