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.

 

Sounds like you maybe have some air in your clutch hydraulic system. Check the level to make sure is not out if you have not already. The clutch system draws fluid from the rear section of the brake master cylinder resevoir. If you look at the very rear part of the resevoir (last 1" ) it should be full of fluid. If not then you will for sure have a leak. The release cylinder is the most common leakage point. Pull the rubber boot back from the cylinder body and if any fluid runs out you will need to replace and bleed the system.
