So I've been having problems for a little while now. It was always a bit notchy getting into gear even before modifications but it wasn't bad enough to warrant putting anything off. After replacing the clutch, I'd say in the range of 3k miles, I started having trouble getting into gear if the car came to a complete stop. This applied to all gears not just first gear. The only way for me to get into gear was to slide into first as I rolled into the stop and just keep the clutch down until traffic started moving again. If I didn't do that I'd have to slam it into either first or third which then allowed me to get into first no problem. That got old after awhile and because the problem was getting into all gears and not just first (figured it would be a syncro) I decided to replace the clutch. This fixed the problem again for about 2000 miles. Now it's back and I can't figure out what's wrong.

-Car goes into any gear fine when cold. Usually takes about 5-10 minutes of driving after warming up the car for the gears to get sticky. When the car is cold everything is very smooth.
-After the car is warm I can't get into any gear at all. If I do get locked out I can usually slam it into third which then allows me to easily get into first.
-This also applies to reverse.
-Changing the clutch fixes the problem for a couple thousand miles and then the problem returns. I also changed out to a slightly heavier flywheel the second time around.
