Ive Got a tranny/clutch problem help please?

My shifting use to be alot smoother into each gear it would just slide right in, now it seems to be sticking and alot harder to push in. Any ideas?
(and no lol its not a driver error I can shift great haha)
I have the GSR tranny and a carbon steel short throw shifter.
