There isn't a separate transmission ECU on these trucks, it's all done through the main ECU behind the glove box.
Having said that, I had a pending random misfire code that kept popping up on my 97. When I was having transmission problems (wouldn't shift out of 1st when cold), one of the things I tried doing to fix it was replacing the ECU with one from a junk yard.
While it didn't fix my transmission problem, the code has never came back since.
Moral of story, an ECU can have issues and throw codes that are not legit. I'm not saying that is what is going on with your truck, but it is a possibility.
