Today I disassembled and cleaned the valve body. Things went pretty smoothly. Some valves were hard to get out. According to the manual, the valves should slide out by their own weight. Some would not do this. I had to smack the valve body with my hand to get them out or gently nudge them with a small screwdriver.
The body wasn't too dirty. There was definitely a coating of graphite like powder on most things. I also found two bolts that were not tight. That certainly would not help my situation.
I did not see any damage to the parts, except both pistons show score lines (pic below). I do not know if this is a problem or not. The seals were pliable and actually looked great. The pistons were hard to pull out of the bores. Also, the low range piston with the fast acting piston sticking out was very difficult to get to move back in. I actually had to turn it over and put body weight on it to get it to move. After cleaning, I lubed it up with trans fluid and it moved more freely.
As I assembled all of the pieces, I lubed them with trans fluid. Everything went in smoothly with no binding.
One valve threw me for a loop because there was an end that came off and a small valve was inside. This shot out when I was cleaning it and I didn't know how it went back together. Took the same valve out of my spare valve body and, of course, it slipped out before I had a chance to examine it's placement! Thank God for the parts list!
Took a peek in the trans pan and I did see 3-4 small pieces in there. Very tiny and only a couple. I know that more pieces didn't leave the pan when I drained it because the fluid all left through the cooler line! Hopefully that is a good sign that there is not internal damage.
Lost light so I had to stop for the night. Still need to reassemble the upper and lower bodies onto each other. I hope this makes a difference in my transmission's performance! Below are some pics of the disassembly. I didn't have enough light to take pics of the parts cleaned.
