The truck: 1992 7.3 N/A E4OD. Came to me with some sort of Jet brand shift controller. I leave it in the stock position.
Pulled codes, but don't know how to make sense of them. I believe they are two digit codes, but have read about three digit codes being used in later models...

Symptom 1: Starting truck, O/D light does not flash. Truck shifts normally up to 35 where lockup should be. Then O/D light begins to blink and does so until the engine is shut down. even restarting within 10 sec, the O/D light does not flash until 35mph
Symptom 2: Start truck and use button on shifter to turn O/D off. The truck shifts normally up to 55. Turn O/D on, and light begins to blink.
When the O/D light is blinking, the trans is in what I assume to be "limp" mode. That is, firmer than normal shifts. Some work was done to the transmission in the past few years. I am in the process of finding out exactly what was done.
Fluid is normal in appearance when compared to new fluid.
I adjusted the FIPL yesterday. 1.07v at idle. 3.90 at WOT.
I have the battery disconnected right now trying to clear out the memory.
Any direction is appreciated as I'd rather not throw parts at this thing. I have a sneaking suspicion something if fd up with my TC.... I'd rather not find that to be the case....
