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 1.

Operation ▶
Description Mode Conditions
Driving mode 2H 2 Wheel drive
(rear wheel)Rear-wheel drive mode. This is used under
normal or high-speed driving conditions on public
roads or highways.
4H 4 Wheel drive
(high speed)This is used under sandy, muddy or snow-
covered road conditions
4L 4 Wheel drive
(low speed)This is used for maximum traction.
When cornering with low speed in 4WD condition,
there could be tire dragging, some
mechanical shocks and resistances in vehicle’s
drive train. These are normal conditions due to
internal resistance in the drive train when the
4WD system is properly working
Mode change2H ↔

70 km/h or less

↔4 Wheel drive
(low speed)
To make the mode change easily, stop the
vehicle on level ground and turn the mode
switch to the desired position and move the
shift lever to "N"-"R"-"N" while depressing
the brake pedal. For Automatic Transmission:
Stop the vehicle on level ground and move
the gear selector lever into the “N” position.
Turn the switch to the desired position. -
For Manual Transmission:
Stop the vehicle on level ground and move
the gear selector lever into the “N” position.
Then turn the switch to the desired position
while depressing the clutch pedal. -
