Thomas is right here also this could be from hard driving clutches filling up the pan clogging the shift solenoids also the coolant temp sensor usually is on the same circuit do the easy/cheap stuff first then inspect the trans connector fluid leaking in or outside water if you find that change that connector it's shorting out next if all is ok & the problems still there drop the pan and change the filter inspect the fluid for shiny metal floating in it and if you find a lot in the pan like thick cake frosting of shavings the clutches are severely worn and the dust/metal is clogging the shift solenoids this is from hard driving racing or from never changing the fluid your car is 14-15 years old by door sticker date and the magnums ,200 300 series Chrysler cars are well known for tranny failure so check it out you know what kind of driver you are and if you get it to no codes then baby this one till its over
