Heater not working, thermostat stuck closed??

Recently it got cooler down here in TX and when i turned on my heater up all the way with full blast, nothing but cool air was blowing out. Yes, the engine temperature was in operating range between C and H. Im thinking thats the result from my thermostat possibly being stuck closed for whatever reason. Luckily, its hot during the day so i run the AC most of the time but just wanted to know due to my next problem; for some reason, the trans. temp. needle stays near the "C" range. I drive, say 20 miles with the engine hot but the needle only goes up 1/4 of the way and stays there instead of normally being in the center of C and H like usual. The two issues seem connected since it sounds like a problem that affects proper cooling and heating of the climate control and transmission. Anybody have suggestions???

similiar thread - I'll bet this is your problem , not the cooling system.
AC/Heat control problem, not the defrost though

Is your upper radiator hose hot? If it's hot, the thermostat is not stuck closed.

A thermostat stuck closed would make the coolant hotter. Hotter coolant would make the heater warmer not cooler.
