Trans is in limp in mode (stuck in second in drive), check engine light on, o/d light off and not flashing. I checked all the trans solenoids resistance myself with an ohmmeter and they were all in spec. Can anyone tell me how to test the i believe 13 wire square connector? My guess is its a wiring problem within the harness since my o2 sensors and trans connectors are on the same circuit. I have no blown fuses. I've reset the pcm for the cel to go off only for the trans to stay in limp mode and the cel shortly following will pop up. If anyone can suggest anything i'd very much appreciate
