SOURCE: 94 Lebaron GTC 2nd gear limp in mode
It has an electical problem. You need to take it to the dealership if you want it diagnosed correctly. It will need to be in limp in, and don't turn the car off as this is clearing the code out of the computer. Leave it running, tell the service advisor your situation and not to turn it off till someone can hook the scan tool to it. This will give them the cause of limp in, and should be able to be resolved after.
SOURCE: transmission shifts to second gear and stays there
Could Be that your TCM is losing power. I would check to see if the TCM is firmly attached to the passenger side fender wall. If not it could be losing the ground.
SOURCE: transmission automatically shifts to low at idle
after my 2003 chrysler concorde is warm I slow down from the hwy and right before I stop my car shifts to LOW gear and stays there until I turn my car off and start it.

But I am afraid I can't tell you want all these codes mean for your car. It was probably not related to the change in fluid that was performed. However, it is serious and should not be driven until fixed. Risk of total destruction of the transmission is too great. I would assume the symptoms are so diverse that it may be a bad transmission control module. Which is about $200, and fairly easy to replace:

But there are other possibilities, such as a bad relief valve could be letting main pressure drop too low.
This is the type of thing which does require an expert and can't easily be done remotely.

Now i dont know a lot about automatics especially modern ones with all this fancy electronics thats used nowdays but i think its a fault with the temperature sensor for the gearbox.But where its located and what it looks like i have no idea it could even be mounted inside the gearbox .Sorry not a very good answer from a mechanic but?? very few of our europeon cars come with auto transmission .Evan when i do know whats wrong i cannot buy the parts for the gearbox as only re-con boxes supplied by the dealer so best advice is to try a specialist in auto box repairs only .PS some of my best students when i used to teach mechanics many moons ago were the girls so no excuses like iam only a girl please

Turns out it was the transmission filter.
