Archived Overdrive stopped working and Im stuck in MO, need to leave for NM on Sunday

[Jason Smythe]

My overdrive stopped working last night. Im doing contract work in MO and I am finally going home after two months on Sunday. But now I need to fix my overdrive. I havent been home in two months. I have a wife and twin 4 year old boys and I have two teenage daughters that I was supposed to spend half the summer with but only have next week with before they go back to school.

Years ago my Throttle position sensor went out and I replaced it with a 5k Potentiometer because I have never had the money to buy a TPS($300-400). I replaced it today and still nothing. I noticed afterward that the protective coating on the wires that I had spliced into the harness to bypass the TPS were rotted away leaving the wire bare. They may have been touching each other. I dont know. So I spread them apart to make sure they werent touching each other. Did they short out something? Is it possible to damage the Overdrive solenoid this way? How do I trouble shoot this?

Thanks in advance for your help

You have 2 wires on the trans control harness. Verify the heavier one has 12V when the key is on. If so a simple switch to ground on the smaller wire will activate OD if the solenoid is good. If you don't have power on the larger wire you will have to back track thru the harness to the shut down relay which may be shorted or gone bad. Start there and see what you have.
