SUBJECT:
All Passenger Models Equipped with 7G-Tronic (722.9) Transmission
No Transfer of Power from Automatic Transmission 722.9
In the above model vehicles if after replacing the electro-hydraulic control unit on automatic transmission 722.9 (7G-Tronic) you experience the below
conditions, this may be caused by an improper installation of the supply pipe for the multi-disc brake B3.
^
No gear can be selected in transmission mode "S" and there is no power flow in the transmission
^
In transmission mode "C" the vehicle can start off as usual.
To resolve, remove the electro-hydraulic control unit as described in WIS document AR27.19-P-0200w.
Before reinstallation, install the supply pipe (Figure 1) per WIS document AR27.19-P-0200w, step 6. Replacement parts are only necessary if the
original pipe was damaged during the original installation of the valvebody.
