mine wouldnt go into first or reverse. i replaced the clutch and it worked... i was positive it wasnt the clutch bc it only had 5 or 6 k miles on the cluth, but evidently it was the clutch. i had to put it in reverse and hold it there and then crank the car just to back out of the driveway. long story short, i replaced the clutch pretty quick and minimized the damage to my trans... id take a long look at the clutch before doing anything else. just my two cents...

mine would upshift fine untill warm as well. but once i got it up to temp it would get hard to slip into gear. maybe the clutch isnt adjusted correctly? i remember thinking the same thing you are though, " no way it could be my clutch, i jsut replaced it" but it was...

Reverse is not synchronized. If the clutch does not fully disengage you will notice it when trying to engage reverse. The synchronizers in the forward gears will mask the clutch dragging but they will be working harder and wear more if you keep driving the car like this.

Google manual transmission synchronizer. All manual transmissions since the late '50s on have had synchronizers to match the gear speeds inside the trans of the gear you are in to the gear you are trying to shift into. When you shift you are actually moving a sliding ring between two gears on a shaft. These sliding rings have a friction material on them that mates with the gear to speed up or slow down the gear so that little dog teeth on the ring engage a matching ring on the next gear without skipping over each other (grinding).
Reverse does not have a synchronizer to change the gear speed it relies on the clutch disengaging all the way to stop the gears from moving in the transmission so the reverse shift can be made without grinding.
I may have some details wrong but this is the general idea. Typically clutch disengagement issues show up with reverse grinding.

Wait, so are you saying that the clutch is not fully disengaging and that's the problem? I did not have this issue until I installed the new clutch and shifter mechanism. I did adjust the pedal but you can't adjust a hydralic right? Th transmission did sit out of the car for a couple of years, should I change or add fluid?

Also the reason your trans does not grind when it is cold is that the trans fluid is viscous enough to stop the gears in the trans from rotating so you can select reverse without grinding. When the trans fluid is hot it is thinner and provides less drag on the gears so you get grinding.
I would suspect your clutch is just slightly dragging when it should be all the way disengaged. If it where dragging worse you would have grinding on the cold tranny also.
*Try moving your floor mat out from under the clutch pedal and see if it still does it.
