I ran a continuity test from the purple and yellow stripe wire from the computer side of the connector (just to make sure the connector isn't an issue) on the inner fender to the same wire that connects to the transmmision. continuity is good, no broken wire.
I also jumpered the wire to ground with the key on and could hear the selenoid click at the transmission oil pan. I did this numerous times to make sure it wasn't intermmintent. It clicked every time!
I'm assuming that eliminates the selenoid and wiring from being the problem.
Does it eliminate the computer or is there another test to isolate the computer as a possibility?
Thanks again guys for following this and giving advice.

Well that coupled with the fact directly grounding that wire did not lock up the clutch during the test drive means you have a internal trans problem. The computer is probably fine, it is very likely it is commanding the clutch to lock up, the trans for whatever reason is just not doing so.
You're now left to possible problems like a seal on the torque converter shaft, a stuck valve in the valve body or a bad torque converter as Mark Kovalsky pointed out.
More often then not because of the type usage these trucks see over the years, problems like this tend to be electrical in nature, just not so in your case sorry to say.
While it is possible you have a weak solenoid, or a very weak connection to it, but still enough connection to make it "click", or both, I doubt it.

It sounds like there's nothing else I can trouble shoot.
The way this truck has been used for the last 15 years is that it has been taken very good care of, always parked out of the weather, not of roaded and always highly maintained, never had an electrical problem. The truck looks almost new still.
But it has seen it's fair share of towing in those years. I changed the trans fluid regularly, some times a couple of times a year. But in hindsight I should of installed a bigger trans cooler.
With that being said I guess I'm not too suprised that it would be mechanical and not electrical.
Do you think a transmission shop can narrow the problem down more with thier equipment. Or is this as far as they can go?

If your truck was to come into my shop with that problem and that code I would recommend pulling that transmission and inspecting the whole unit to see what condition its in. Based on that I would recommend a minimum of a converter replacement and a pump rebuild with modifications for lock up and pressure control, but in most cases there will be other areas inside the transmission that need to be addressed and it would in up as a complete rebuild.
Do it right and do it once.

jk080,
With my description of every other aspect of the transmmision working flawlesly, at least it seems so. With the exeption of the overheating in OD, do you think that other damage has occurred? Or just worn out with mileage, or both?
Your description shows that you have a lot of experience and I'm open to everybody's opinion.
I'm just trying to get off on the cheap since I can't afford a rebuild at this time. But if that is the best way to go I'll hold off for now. As it has been said before don't throw good money after bad.

92m, you should really have started your own thread but the answer to your question is no. The bellhousing is different. You need one out of a 300 six, 302 or a 351 motor.
MT, you have some great info here. Super electronic diagnostic advice from danr1, great tutorial on the converter operation from MK and practical advice from a professional trans builder, jk080.
We all need thinking time now.

Although we did not narrow it down to the exact problem this thread might be informational to others in the future.

Yea that be my suggestion, hate to see ya pull the trans and only installing a new TC just to end up right back in the same boat after all that work.
Pulling one of them monsters out and putting it back in is no fun task, add to that if its a 4x4 model and you got a job, not an adventure.....

Similar issue for me as my truck drives fine when the overdrive button is in the off position. If overdrive is turned on it doesn't want to shift around 45-50 mph. It kind of stalls and eventually will shift but sometimes it will lurch into it.
I usually just drive without overdrive on. Tranny was rebuilt about 7-8 months ago with less then 3k mileage on it.
