On going Transmission problem for E430

Question

Hi Fanatic,
Spent 4 hours under the car today. Everything went well except no change, still wont go into gear.
Carsoft was showing 0704 error I cleared that and tried to shift without success.
shifter is connected, I'm thinking that the gear shift in the valve body went in correctly. what is next on the list.
The solenoids looked unmarked, and the oil seemed dirty but no signs of iron fillings, there was a small magnet in the oil pan that was clean.
