The suggestion to buy an old NGS when an simple and relatively inexpensive alternative exists seems to be.... different.

Thanks for the info. I don't want to hijack this thread, my truck is a 1996. Cheers!

WTF?
So what's your theory then Big Dog Sho 89?
You are full of answers
I'd have had the truck fixed yesterday with my NGS and a few test parts (just exactly like what the Ford manual says)

My theory is that, if the OP or the recent hijacker fails to follow troubleshooting instructions given over three months ago, he's just going to go around in circles.
Since neither the OP or the recent hijacker have done so yet, any speculation as to cause and needed repair is not useful at this time.

My experience (on a sample of ONE) is also that broken wires don't cause the OD light to flash. On our '03 they prevented the light from illuminating, ever. Granted I don't recall which wire(s) were broken.
I value manic's insight but when it comes to electrical SHO is the big dog, actually. And when it comes to transmissions in general Mark K has forgotten more than I'll ever know
That said, I guess it isn't that difficult to pull the column surround and look for broken wires, but I think it's a waste of time here

@ CARGO " looking for a diagnostic tool " Innova makes some good entry level scanners. Think about the future. Pay as much as you can now so your not looking again in 2 years. Another great tool is a power probe. I bought the 5610pro scanner for my son and the PP3CSRED power probe that is all a non-pro needs to get started.

... the quick/easy and often proven problem with the intermittent overdrive off lamp/shifting issue seems to be the short wire in the column, I'm doing that while I look for the tool.
I started a thread about this but I will ask it here, my shifter stem has two of the three pins that go to ground when I test them (stem pulled, disassembled), do you guys know if that is correct?

Uh, no. Re-read the WHOLE thread...
That does not sound very likely. Review your testing procedure. That result, if correct would require TWO wires to have both chafed and shorted to ground or to each other while one is shorted to ground. Certainly not impossible, but is not very likely unless the harness is a chewed up and mangled mess inside the **** lever tube. You'll have to do a visual.

Thanks for the help. I took the stem out of the system (unplugged it) and same problem occurred, overdrive disconnects randomly. It will do the same thing idling setting in the driveway, at least the overdrive light goes on and off. I did purchase a BT dongle and ran the FORscan demo version yesterday, no codes. I am getting under the truck in the next couple of days to unplug the trans wires to clean/look for issues.

The OD cancel wiring doesn't go to the transmission, it goes to the PCM.
1. Get the free extended license to unlock everything.
2. Use forscan to monitor the OD Cancel button's PID and see if the PCM is seeing it change state. Might be a wiring issue between the column and the PCM or the PCm itself if so.

Something doesn't compute...
1. What are you working on? Only thing I've seen is that you have an "F350" (wrong forum, if so....)
2. Never seen or heard of a P1111 DTC on a 97+ F150 (this forum).

You are right and I already stated I did not want to hijack this thread. I have a 96 F-350/7.3, I did post this on the right forum but never really got a reply. My initial post here was simply about the lack of IOS/Mac support of FORscan (apparently because Apple has zero customer support) asking if anyone recommend another program. Anyway that is the code that came up. Per your recommendation I did run the check to see if the switch was showing up.
