Torque Converter Recommendation
I'm looking for a recommendation on which torque converter to buy for my 93 Ford F250 7.3 IDI. I'm having what appears to be a common issue where the OD light comes on and the truck goes into limp mode.
The transmission was rebuilt and had an issues several months later. It was taken back and they rebuilt it again. After that it worked fine for the longest time. At one point the truck had a trailer hitch / cable issue and it seems like shortly after that repair it started having this limp mode issue. I read a forum post that tied the limp mode issue to tail lights / trailer wiring.
I've read so much about the torque converter being the main issue, I've decided to start with replacing it since the company that did the transmission rebuild was said to use cheap converters. So what I'm looking for is the EXACT converter to purchase that is higher quality and from Auto Zone, Rock Auto or Amazon. I see way to many options and I'm sure I'm simplifying this more than I should. Thanks in advance for any help and please ask questions if it will help you make a recommendation.

1st off I can't imagine faulty tail light wiring causing your Transmission to go into Limp Mode as the Electrical Circuits are not common to the PCM.
IF your Tranny E4OD is in limp mode OD Cancel lamp Flashing then you need to read the Code from the PCM to determine the method of troubleshooting before just Assuming the Torque Converter is bad.
there is no Torque converter sensor to make it go into Limp Mode.

The codes were 23, 62 and 67. The main code was 62 which is excess torque converter slippage. The code 67 was park neutral circuit failure.
Some where in my research I saw a thread on wiring to the tail lights and or trailer wiring hitch being an issue and I connected that with the OD light coming on.
Thoughts?

23 is FIPL 62 being converter Clutch slippage .... 23 is often caused by not holding WOT while pulling codes 62 is often the solenoid pack plug. https://www.ford-trucks.com/forums/1...s-harness.html
67 I would do pinpoint tests on the MLPS
I would be more suspicious of electrical issues... while the lockup piston could be cracked causing the 62
I still don't see relationship with tail lights.
Maybe @Mark Kovalsky will Chime in and give more insight ....

I really appreciate your feedback! I must tell you that I am new to working on a diesel so please bear with me and some of my questions.
Thanks for the help. That link was really encouraging and I'm completely down with spending a few hours doing some cleaning and wire repair...
Thanks again and I'll let you know how it turns out.

yeah I hate to see someone spend money if it is not needed always best to verify the issue first.
My experience is that anytime a torque converter has failed I had to go thru the Tranny too

There is a quick way to see if the converter clutch apply piston has cracked. Open the inspection plate on the bellhousing and look at the front face of the converter. If it's blued or otherwise discolored from heat the converter needs to be replaced.

Code 62 on these trucks is almost always present whenever something electrical goes wonky on these E4OD equipped trucks. Don't jump to condemning hard parts or you could still see the issue. Start with focusing on the Code 67 (probably a faulty range sensor) and once cured, you'll likely no longer have the 62 slip code either.
