Disassembly of valve body on 722.5 gearbox

Hello!

Today I decided to get deeper into the mistery of the valve body of my car's gearbox. Due to the fact that my mechanic was just changing the malfunctioning body with another valve body (that was not working neither) - we did that 4 times and the transmission still wouldn't work - I took matters in my own hands and I opened up a "tranny brain" to clean it properly. It seemed to be a very good ideea because the only things I didn't find in there were dead dinosaurs. The damper housing was amazingly dirty and some of the pistons were blocked by tiny parts of destroyed clutch discs. I cleaned the whole thing but, when I reassembled it, I got a part that didn't fit anywhere. It's a metal valve with a spring. I looked on the pictures I had and it's seems that it's an optional valve. The whole body has been opened up before (looks like it) and they put in parts from another one. And, instead of a check ball, they put in that spot that valve which was supposed to be somewhere else, anyway. It's number 5 on the picture, but I found it right instead of one of the balls in the middle. Did any of you disassembly the valve body? Is there any tutorial that I can check out?





PS: It seems it is the same valve body used on all the 722 trannies since '81 till '95. With minor changes during the years, off course.
