BMW 5L40E with Harsh Shifts!
This car has 59000 on it came in with hard shifts. It was very clean when I pulled the pan. I did the valve body first, pressure regulator and feed limit bore (some wear here) but no change so I sold the overhaul.

Note the severe wear of the aluminum on both sides of where the Teflon seal rides. I never found any sign of the rubber expander maybe this is what happens if you leave it out. more
