This variable all depends on the engine/transmission application on said vehicle. Be more specific.
You will get lower gas mileage. The tcc solenoid locks up the transmission to get better gas mileage at higher speeds. I suppose it will wear the transmission slightly faster as well, but the main effect is lower gas mileage.

The gas mileage of a 1981 Corvette can depend on whether it is automatic or manual transmission. With automatic transmission, it gets 15 mpg on the highway, and 21 in the city, but with manual transmission, it gets 14 mpg on the highway, and 22 in the city.
Depends on the engine, transmission, gearing, etc.

Need to know the year and engine/transmission info
Actually, not terribly poor mileage. It really depends on if it is a automatic or a manual transmission, as well if it is equipped with a 350 or the more economical 305 or even 6 cylinder engine. If you have the 305 version with the MT, 17-18 mpg is the usual.
