5. Secure control unit (7) with self-adhesive felt on the transmission tunnel.

   The control unit (7) must be fixed in place so that vibrations and damage are ruled out. This must not adversely affect the removal/installation of adjacent components.

6. Remove damping material on the transmission tunnel in the area of the control unit (see arrow in picture). Strap down excess lengths of wiring harnesses and fix in place.
