Just pull back the passenger carpet and unbolt the steel liner. TCU is right next to the airmatic.

There are several black boxes under the passenger carpet plate, so make sure you send the TCU out to be tuned and not your airmatic module.

Is the TCU for the E63 located in the same place as the E55?

No its inside your transmission on the valve body. It is what you would think of as the conductor plate on a 722.6.

When you're looking at the 3 boxes it is the bottom driver's side box. It will have 2 connecting wires.
