Hello All,
04 T&C 3.8 231k
Got a p0700 and p0755 code and sure enough, the 2-4 solenoid was reading 45m ohms instead of 1.5. So I replaced the solenoid pack today, cleared all the codes and hit the road. Still in limp mode with a p0870 code O/D pressure switch circuit. I checked the solenoid pack, switch is open and without the transmission simulator I know no way to test if it's stuck open or working properly. I tested the wiring from the solenoid pack to the PCM and it's good at least all the ways I wiggled it. My only other thought is to try and disconnect just that one wire from the solenoid pack, and use a test light to see if the switch closes during the self-test during the first drive after clearing the codes.
I'm at a loss and I could use some help if anyone has any ideas, please share!
