1. OVERVIEW
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 -
