Looking for walkthrough ... electrical troubleshooting of TCC Stuck On tranny prob

I saw a very complete walkthrough of steps to take to rule out electrical problems before tearing into the 4T65E tranny. After an hour of Google, I can't find it again.

I thought I had bookmarked the thread, but after checking all the computers, I don't have the link.

Does anyone know the thread I'm looking for? It may not be on this site ...

I'm desperate ... I really don't want to tear into this tranny, especially if it turns out to be a simple electrical glitch.

Thanks so much for all y'all's help.

in your case AllDataDiY ($25) would be a wise investment.

I used to have an AllData account for each of the cars, but it was such a joke .. .nothing but the same info I could get for free with some google searching. But, that was 6 years ago. Did they get any better?

I've seen this specific info in a web forum .. and I can't find it now, nor can I find a bookmark that I thought I made.
