The heat in my 2005 dodge grand caravan will go in and out. When I am driving at a decent speed it is ok, when I stop at a stop light, or slow down to about 25, it starts to blow cold air. It will go from hot to cold while driving as well.

On a Chrysler product, the blower switch and resistor provides the ground circuit for the blower motor. The highest speed circuit which is dark blue and gray goes thru the resistor directly to the fan switch. The other speeds go thru the resistor to slow down the motor. One wire from the switch should be a direct to ground, the other 5 wires should have voltage coming from the blower motor thru the resistor.
Sound like the fuel filter or the fuel pump or both at fault. Check the fuel pressure while the engine is cold, to do this turn on the key switch just long enough for the fuel pump to come on and then off. Turn the key off and look under the hood on the fuel rail for the test port with a valve stem cap, remove cap and using a rag and small screwdriver cover the screwdriver while mashing down on the valve stem inside test port. If you have alot of pressure coming out then it's ok. If not then the pump and filter is the problem. Fuel pressure should be around 49 psi. Hope this will help you.
could be a sign of wornedtranny regardless of miles and it depend on how hard the vehicle has been driven and pulling. some tranny has better luck than others and before jumping into any conclusion my advice is to take to transmission shop and have them drive the car and check it out, should not cost you anything. Amoco probably be a good place if you have one near by.
You have a circulation problem, heater core may have restriction that why heat only comes when you drive ,also you may have a thermostat that stuck in the open position. Good Luck
