Group: 27
SUBJECT:
All Passenger Vehicles with 722.9 (7G-Tronic) Transmission Adaptation Values of the 6-5 Downshift Close to the Negative Limit
In vehicles equipped with the 722.9 (7G-Tronic) transmission, when evaluating the adaptation data in the transmission electronic control module, if it is noticed that the cycles of the adaptation data of K1 are very far into the negative range on the 6-5 downshift this alone is not cause for a technical repair if no complaint exists.
Only if the adaptation data of K1 is also at the limit value for the 2-3 shift is there an indication that a technical malfunction exists. For further information about K1 replacement, refer to Star TekInfo DTB P-B-27.60/88a.
If other complaints exist regarding shift quality, a complete evaluation must be carried out as per the EDAC 722.9 diagnosis tree.
