Sometimes the shift can't be accomplished at all , without first, pulling the pedal up manually with the top of my foot (under the pedal)! I bought the parts so the shop won"t warranty the job if it's because of them and the supplier won't either because too much time has elapsed, soooooooo that leaves ME and at the moment I have just pulled the tranny; The release bearing fell out in my hand (fast reflexes) and is seemly in good shape but isn't it supposed to be attached to the arm? Any help would be greatly appreciated. I should add that I had the shop bleed the system and install a new slave but there was no improvement.
What brand clutch did you buy? Reason I ask is that with diaphragm design clutches, you cannot be mixing parts. Diaphragm clutches do not like to be pushed over center (when the clutch "fingers" are literally turning inside out) as it will cause the clutch cover to want to stay depressed, so the pedal stays down momentarily, even without your foot on the pedal.

Several things can lead to this problems, including miss matched parts, throw out bearing installed incorrectly, hydraulic system issues, loose clutch cover bolts, etc.
