I have a 2003 Grand Caravan Sport with 3.8 liter. I've been trying to fix what I thought was going to be a simple sensor issue that has turned into a 4 month standoff. I parked the van at home after an uneventful drive home from work one evening. When I returned the next morning to leave for work I noticed all of the gears on the instrument cluster had boxes around them, then I noticed the speedometer was not working, the odometer was not counting miles and I could not get out of second gear. So far, I've done a fluid flush and filter change, replaced both speed sensors, replaced shift solenoid, replaced TCM, replaced PCM. Replaced range sensor, front module on power module, replaced all relays, swapped out wiring harness and still have not gotten anywhere. I checked the EATX relay with the key on and only get power to pin 87. I know this is not supposed to be like that I'm just so exhausted with this van that I need a little direction before I push it off s cliff. Any suggestions anyone might have is greatly appreciated, thank you!!
