Here's the situation:
(1998, 4.0L, 4wd, 5R55E Auto, 230K miles)
I had gotten home from a 1200 mile drive two days before transmission failed. At the time it failed I was driving it for the first time since the trip and was about 6 blocks from home. I was turning out onto a busy street from a stop sign and gunning it pretty good to get in-between traffic and I suddenly lost (Drive). The engine was still revving, but the truck was no longer moving. After some panic I downshifted into (2) and the truck started moving again. I continued to the store, and I think I used both (1) and (2) on the trip there and home. I can't recall for sure but it's possible (Drive) worked on the way home.
I made it home but eventually lost all drive, even in (1) and (Reverse). I had seen no leaks of fluid at any time, but added some fluid (don't recall how much- probably a quart or two) just in case and it didn't seem to make any difference. After some searching of those symptoms on this forum I figured it was probably time to rebuild the transmission. I had some problems removing the rear drive shaft as part of the process of removing the transmission so the truck sat for quite a while.
I finally got the transmission out and disassembled, and I didn't see anything that looked like a problem. So I'm thinking what: the Valve Body and/or Pump is failing? Does the Torque Converter fail and what does that look like?
Here's something else I didn't notice until I got the transmission removed: it was a previously "Ford Remanufactured" transmission. (I got the truck in 2016 with 180K or so miles on it.)
Thoughts?
