Truck threw this code about a year ago my brother said and he's been driving since the (OMG only my brother trust me). So now he wants to sell it and yada yada yada. So the little reading I've done it sounds like an electrical issue for the most part. I checked (exterior of trans only) the wiring harnesses and connectors they look ok. I checked the trans control relay and swapped it with a known working relay and no affect. I looked at the PCM/ECM connections and they seem ok. My next thought was to either start testing using the multimeter or just drop the pan and replace the gov. Press. Solenoid and also take opportunity to add clean tranny fluid and inspect things. Or should I be looking more towards the PCM/ECM as being bad? What's your opinion
Ps. I did pull the trans control relay. Put it in drive. It did start in 3rd gear and I was able to down shift into 2nd and 1st gear.
have the same problem?
