CLS55 savage

I have a 2005 G500 and I have replaced the conductor plate, TCM, and plug(722.6 trans). The problem I’m encountering is the transmission is not shifting out of 1st gear. It was doing this prior to the parts replacement. I have put it on a lift and I’m getting “output” numbers from the front speed sensors, but the rears I get nothing. Here is a screen shot. Any help would be great as I cannot drive it!!
