Q: Replaced trans, won't shift on 1998 Mercedes-Benz S420

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
We replaced the trans, & it won't shift, even manually. We replaced the tcm with a used one, but neither the old one or the used one has voltage to the solenoids. The white wire (+) has no voltage. It supplies power to the solenoids from the tcm.

What's the line pressure? Does the TCM see the correct gear positions when you move the selector arm? Is there any DTC in the TCM, ECM perhaps the rest of the modules?
