Mercedes first introduced the "722" models in model year 1980. The 722.3 is found in most models and the 722.4 is found in the 190 vehicles. This manual covers the procedures necessary to overhaul and repair both of these units. This manual also covers the differences between the units in the valve body and governor. The basic internal components such as the pump, gearsets, drums clutches and bands are the same. This manual includes both the original manufacturers information along with some of the engineering changes and updates.

We wish to thank Mercedes Benz for the informationand illustrations that have made this booklet possible.
