sr20 tranny problem

[mytagsucks]

Looked in alot of fourms and places on the internet but I'd love the opinion of so zilvians on this one. For the first week of driving my sr after I had it rebuilt the transmission shifted buttery smooth but it gradually has become harder and harder to shift. It started with a grind while going into reverse. Really bad grind but it was NEVER there before and i never mis-shifted or anything. Now getting into first makes my shoulder want to fall off and I'm a pretty muscular guy. While rolling i can get it into first easy though.

Now while I'm in first, the car rolls with decent speed even when i have the clutch pedal to the floor. And in order to stop i have to keep my foot on the brake but when I do so the rpm's seem to drop quite a bit.

Shifting into the rest of the gears is easy but still not smooth like it once was. slight grind into fifth about half the time too. Now is this a clutch problem or a tranny problem? New slave cylinder? I'm sure my syncros are shit by now because of this abuse but the cars my daily and i'm strapped on cash but, other than that could it be some clutch adjustment problem, possibly need a new clutch? I just don't see how it went from running great to complete shit in such short time.....
