P0700 is a code to tell you that there is a code(s) in the transmission control module. To read them usually takes a higher level scan tool, most of the code reader machines won't read the transmission codes. The dark and smelt bad for the fluid describes burnt fluid from internal transmission heat, usually because of clutch slippage. Either from worn parts or lower that normal pressures. In this case it could be that the wiring changes have caused it, however the first step would be to use a higher level scan tool to read all of the codes. The P0113 code would be for a failed intake air temperature sensor. That could also be wiring related. The way to tell would be to look at the freeze frame data stored for the code. If it shows the IAT temperature to be -40 degrees the wiring to the sensor is broken or disconnected.
