1. OVERVIEW
▶DC 5-Speed Automatic Transmission
DCAG 5-speed automatic transmission is an electronically controlled 5-speed transmission with a
lockup clutch in the torque converter. The ratios for the gears are realized by three planetary gear sets.
The 5th gear is designed with a step-up ratio of 0.83 as an overdrive. The selector lever is controlled by
electronically and mechanically. The gears are shifted by the corresponding combination of three
hydraulically actuated multiple-disc brakes, three hydraulically actuated multiple-disc clutches and two
mechanical one-way clutches. This electronically controlled automatic transmission adjusts the
operating pressure to provide proper shifting in relation to engine power. This function improves shifting
quality significantly. And, the driver can select "S" (Standard) mode or "W" (Winter) mode according to
the driving conditions. This automatic transmission provides two gears even during reverse driving. The
internal sensors and controls are connected to TCU by cylindrical 13-pin connector.
DCAG 5-speed automatic transmission offers the following advantages:
Improved shifting quality
More gears
Extended working life and reliability
Reduced fuel consumption
