94 Ford Ranger 183000m clutch

I know that it is self adjusting, if that helps any. I had the clutch assembly replaced about 2 yrs. Ago. I don't want to be swindled if the parts that need replacing are the shifter cables or heaven forbid the whole syncro assembly. My friend had that done and it was expensive. The cars I used to drive were 80s models, mostly Fords. This was the newest vehicle I own, so I'm not familiar with 90's auto tech. The most I have replaced myself were tires, brakes, exhaust, leaf spring brackets, and upper engine parts. Basic stuff that runs all on the same repair principles. I didn't want to do any work myself and mess it up, so I took it to a shop for the clutch. I have a reservoir for fluid topside. Any of this help?
I really can't complain too much--this truck didn't start to fall apart until 2 years ago. But now that it has started I have put over $4000 into it in two years.
