That is the difference between reading codes & reading the computer readings. The codes don't necessarily mean the part is bad, emissions, electrical shorts, vacuum leaks make sensors set codes. YOU MUST READ THE SENSOR READINGS>

That year dodge was known for bad transmission's. I dont live near you so i cant help you with a good transmission shop.if you find a good mechanic you could buy a aftermarket trans from (jasper engines/Transmission's) for example and have your mechanic install it.

If it cranks good but won't start, have a helper crank it while visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure. Also, check fuel injector pulse. If your missing several system, an example, at the ignition coil and fuel injectors, engine cranking, check the dark green wire with orange tracer for voltage? If no voltage that leads back to asd relay. I'm not saying the relay is faulty. Your computer has to see both the cam and crank sensor signals or it may not ground the asd relay. The asd relay supplies voltage to several systems.

You should be able to access the Prodigy Instructions ie Wiring Diagram At google. Maybe an install video on You Tube. Make sure everything you do is properly fused. Any thing as far as color codes will need to be Prodigy specific. Prodigy may have a 1-800 Tech line. They should be able to E-mail you a PDF file.

Hi, This is usually a sign of LOW Antifreeze/Coolant. Check your fluid level. - WHEN THE TRUCK IS COLD or you can get burned by hot fluid!! Make sure you add a 50/50 mix of antifreeze and distilled water. GL, TD

Run a diagnostic test to find out where the cause is. Could be sensors, Mass air flow meter, plug wire.

Make sure battery has a full charge and battery connections all good. Make sure your charging system is working properly. Note the blower diagram. The top wire is voltage, the bottom wire is ground. Use a testlite to check voltage. The resistor block and heater control are on the ground circuit, if you think a problem with ground, just use a redundant ground for testing, that other stuff doesn't matter at the moment.

It,s under the hood on top of the radiator !

ambient temp sensor outside faulty or the interior display or both

Something could be binding in the steering mechanism. And are you sure the new replacement pump is working properly? Just because something is new is no guarantee that it works.

Faulty reverse light switch, remove cables to the switch, if this cures the fault replace the switch.

On the side of the engine block and cylinder head There may also be some located on top of the head under the valve cover

up under the dash on drivers side. Not under the hood

You will need the dealer to run a test of the system to determine the faults that are present.

Temp blend door may be stuck. If it also will not go from defrost to AC the mode door may be bad also. Possible linkage or connection issue .

Depending on what it is leaking it could be axle seals or wheel cylinders
