722.2 (K4C025 and K4A040)

The 722.2 is the first of the series, launched in April 1961 for the W111 220SEB, later replaced with the 722.0 and 722.1. It is a 4-speed unit and uses fluid coupling (also referred in some manuals as hydraulic/automatic clutch).

722.1 (W4B025)

The 722.1 is a 4-speed unit, the last released in the series, that also uses torque converter. Used in l4, l5 and l6 engines, it was not used in V8 models because it wasn't designed for handle that amount of torque, instead the 722.0 was used in those engines. In normal situations, it starts in 2nd gear, but it will use 1st gear if kick-down is actuated (full throttle) or if L position is selected in gear selector.

722.0 (W3A040 and W3B050)

The 722.0 is the strongest of the series, starting with the W3A040, W3B050 and a reinforced W3B050 (722.003) exclusively used in the W116 450 SEL 6.9. The second in the series, it was released initially for the W116 450SE and SEL in August 1972, and it uses torque converter instead of fluid coupling. The transmission is used in V8 engines as a 3-speed unit.
