Mercedes 722.0 Automatic TransmissionThe Mercedes-Benz first series of automatic transmission, designated with series model numbers 722.0, 722.1 and 722.2, is a family of three and four-speed transmission for engines with longitudinal layout on rear wheel drive passenger cars.

This series were the first Mercedes-Benz true automatic transmissions developed in house. Alternatively, they bought other automatic units from other vendors, such BorgWarner.

Mercedes 722.1 Automatic TransmissionBefore this, the company used semi automatics systems like a vacuum-power shifting for overdrive or the "Hydrak" hydraulic automatic clutch system.

Control of the fully automatic system is fully hydraulic and it uses electrical wire only for the kick-down solenoid valve and the neutral safety switch.

Three-speed units use two planetary gear sets and four-speed units use three planetary gear sets.Mercedes 722.2 Automatic Transmission

Mercedes-Benz 722.2 4-Speed is a (Hydraulic) Automatic Transmission.

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).

722.0 (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 a torque converter instead of fluid coupling. The transmission is used in V8 engines as a 3-speed unit.

722.1 (W4B025)

The 722.1 is a 4-speed unit, the last model released in the series, that also uses a torque converter. Used with l4, l5 and l6 engines, it was not used in V8 models because it wasn't designed to handle that amount of torque, instead the 722.0 was used in those V8 engine applications. In normal situations, this model transmission rests stationary in 2nd gear, but uses 1st gear when the vehicle starts moving and throttle is applied, or if L position is selected with the gear selector.
