AUTO TRANSMISSION
KYRON SM - 2005.09
T-Tronic DC 5-speed automatic transmission is an elec-
tronically 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 de-
signed 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 operat-
ing 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.
