The good news is it’s a RWD Chevy S10…should be able to find a used transmission in a scrapyard without any trouble. Just find one that was treated nicely…drain a small amount of fluid, and see what the condition is before you get it. Check the mileage. Lower mileage, and good looking fluid will be a hint of the condition…not a guarantee, though. RWD is much easier to change than a FWD.
New clutch, pressure plate, throwout bearing, and possibly a machined flywheel (worst case, a replacement from the same donor vehicle - if it’s there). You could rectify the entire situation in a few hundred $$, I would guess less than a thousand. That all depends on the rest of the vehicle. Is it worth fixing up? A few phone calls can get you prices so you can decide. Cheaper if you can do it yourself - not everyone can.
Having said that, it’s 16 years old. You could just junk and replace it.
