Automatic Transmission (AT), Function

Transmission Without Touch Shift 722.6 In Model 163

Automatic transmission 722.6 is an electronically controlled 5-speed transmission with a lockup clutch in the

The ratios for the gear stages are achieved by three planetary gear sets. The 5th gear is designed with a step-up
ratio as an overdrive.

Shifting is initiated electronically. The gears are shifted by the corresponding combination of three
hydraulically actuated multi-disc clutches and two mechanical freewheels.

CAUTION: Inspect headless setscrews and plastic clips, replace if necessary.

NOTE:

There are 6 headless set screws and plastic clips.

NOTE:

There are 4 headless set screws and plastic clips.
