shifting probs!?

[shoguntalon]

hey can anyone help me? My car is having trouble going into gear. it shifts normally when i first start driving it but after 10-15 min after driving it gets hard to shift into gear. The clutch pedal doesnt stick to the floor. I replaced the clutch about 1000 miles ago. I just did the clutch master cylinder and slave cylinder. because it only starts having problems after i have driven it for awhile and has warmed up I was thinking maybe I got a bad clutch disk or somehow i damaged the synchros or something inside the tranny. But if anyone has had a similiar problem or can even understand what i am trying to explain and got some advice on what i should do. I don't want to replace a tranny or clutch again unless i have to ofcourse.
thanks

p.s. i took it to a dealership and another shop and niether knew for sure what was wrong they all just wanted to just put in a new tranny and hope it worked

does it grind or anything, a good way to tell if its the clutch or tranny is put it in gear when it starts to not work properly while the car is off, push the clutch in and try to start it, if it moves then its your clutch, if it doesnt than its your tranny. hope that helps ya good luck.
