Mhh, good observation, the Corolla in question uses the same brake fluid bottle for both the clutch and brakes.I've also experienced something similar in my fiesta. I changed the clutch, changed gear oil and selecting gears in the morning was as tough as counting how many hair strands I have, but it would get better when the car warms up.
Initially I thought I needed to bleed the clutch system but I could find the cylinder anywhere.
I went to Ford bought their gear oil, that didn't make a big difference until one day I changed my front brake pads and bled the system, from then on my gears would just slide through, turns out MK7 fiesta's use the same line as the brake cylinder (or so I think)
OP, maybe change the whole clutch system, the gear oil, do a bleed and see if that makes any difference.
We'll be changing the gear oil and perhaps bleeding the brakes for good measure, I am reluctant in advising on changing the more expensive items like the clutch, thinking of leaving that for last, when everything has been eliminated.
I did notice the clutch does have a high bite point though, it's an old car and the clutch could possibly be on its way out. The car still pulls like a train though when the gears are working so I am more inclined towards the fault being related to the gearbox and its associated components.
