TORQFLOW TRANSMISSION
Komatsu TORQFLOW transmission consists of a water-cooled,
3-element, 1-stage, 1-phase torque converter with lockup clutch
and a planetary gear, multiple-disc clutch transmission which is
hydraulically-actuated and force-lubricated for optimum heat
dissipation. Gearshift lock lever and neutral safety switch
prevent accidental starts.

STEERING SYSTEM
PCCS lever, joystick-controlled, wet multiple-disc steering clutches
are spring-loaded and hydraulically released. Wet multiple-disc
steering brakes are spring-actuated, hydraulically released, and
require no adjustment. Steering clutches and brakes are inter-
connected for easy, responsive steering.
