Can't shift gears

[skywalker]

I am having problems shifting in my car.

1994 Mazda Protege 194,000 miles 1.8 Liter Manual Transmission

It runs fine when I can get it into gear. (No slippage)
When I push down on the clutch the pressure doesn't feel right.

My Chilton Manual doesn't have any diagnostics but it did have
sections showing replacement of the master clutch cylinder and
clutch release(slave) cylinder.

Thanks for any input.
