If you know answer to this because you have an extra 722.3 valve body, I'd be willing to buy that valve body from you.

Looking for a spare, junk 722.369 valve body. I'll pay a decent price + shipping. Poor condition is fine. I'm trying to understand the layout of the springs & valves because I think my no upshift problem could be due to how i mis-assembled my valve body .

I think any 89+ 722.3 valve body will work - a close match is the 722.369 from E320, E420 etc or the 722.358 will probably work well.
Will pay $65 shipped, or higher if needed.
If this number's on the outside, it will work:
