Overdriv won't engage
Hey all I have a good one for ya. For a while now my dakota's overdrive hasn't been engaging. I replaced the solenoids in the transmission thinking that would fix it, but that did nothing. I got my mechanic (who is also a good friend) to take a look at it and he took a scanner to it and said something was up with the PCM. He said for whatever reason the programming had buggered up, or so we thought, and was telling the transmission it consistently -40 celcius out. So we replaced all the sensors to no avail. He tried to reset the PCM but for whatever reason that would not do a thing. So we figured a new PCM would fix the problem. I went to the junkyard and got a pcm for my dakota for a $150. Hooked er all up and fired the truck up and went for a drive. Nothing, overdrive will still not engage. Is it possible the wiring harness is buggered up? Maybe a bad ground?
Ahh OK I see. Now if I tried to start it in a gear other than park neutral and it wouldn't does that mean it is working?
It would mean that the switch is ok, but it would not check the complete path of the insulator that makes contact with the switch...

Well we got it working, but not in the typical way. We changed things up slightly and the computer no longer reads temps from the transmission, but from the engine. Changing this caused it to engage. Thanks for the help all
