Welcome ti DT!
Before you do anything, clear the codes and see what comes back. There's no need to chased ghosts. Double check the fluid level and double check the "How To" on the transmission dip stick.
.... This is from a past DT thread:
You can do what is often called a "hard dump".
We (techs) often do this when we need to totally reset the ECU and either don't have the proper tool close by (too lazy to walk to toolbox and get it) or just are "in a hurry".
First, disconnect positive+ battery cable at the battery and ground it to the chassis. Yes, the POSITIVE CABLE.
Wait a few seconds, 30 won't kill ya.
Now reconnect the positive cable. Careful, no sparks now.
Get in the vehicle, turn ignition key to on (run) position, now depress fully and release the gas pedal 5 times to set the TPS to WOT. (Make sure the floor mats do not keep the pedal from going WFO)
Turn the key to off, wait a min, and you should have cleared everything in the ECU except for the factory programming.
The hard dump does not effect the (factory) alarm, the only thing I noticed is my radio presets, as this method came from a working Chrysler tech, I doubt if there are any negative effects.
When you have the new codes, you may have better idea what's wrong.
Keep us posted okay?
If you start a thread, be responsible and post the final outcome.
