Hard to shift after clutch replacement

Car became hard to shift into gears after a clutch replacement. Replaced clutch slave cylinder, didn't fix it. Then replaced clutch master cylinder, didn't fix it. Bled each time multiple times using different methods. There doesn't seem to be any air in the lines but I can pump the pedal a few times and it shifts better or flawlessly. I am out of ideas, there doesn't seem to be any leaks, and I have tried every option of bleeding except power bleeding. It has gotten way better than it's worst, however, still is not completely fixed and leaves the car unable to be driven.

When you press the clutch pedal the first time, does the slave cylinder move an appropriate amount?

If pumping the pedal makes things work correctly, you have air in the system. Period.

How are you bleeding the clutch? I am not familiar with the 1st-gen MINI, but I do know that some cars with hydraulic clutches can be difficult to bleed.

If you are certain that you have gotten all the air out, and the problem recurs, then you may have some kind of leak. Inspect the slave cylinder (if it is accessible), the master cylinder, and the lines for any signs of wetness.

A power bleeder will make your bleeding process much easier, especially if there is trapped air in the system that you cannot get out. It may not be a bad idea to invest in one: Mini Cooper & Cooper S (R50/R52/R53) - Brake Hydraulics - Page 5.

Also, not that this is your issue, I'd check your shift linkage and make sure they're not damaged/corroded. If those bind it can cause shifting issues, but your issue sounds like it's more likely related to air in the system or something else.
