SYSTEMS OPERATION - Continued
Cross-drive transmission is controlled by driver with steering and shifting
controls and brake pedal. Transmission hydraulic torque converter multiplies engine torque
providing automatically variable torque output through planetary gearsets and hydraulically
operated clutches and bands to final drive units, sprockets, and tracks.
TRANSMISSION ADJUSTMENTS. Adjustments are made to mechanical linkages on rear of
TRANSMISSION MOUNTS. Located one each side of transmission serve as powerplant
installation guides and mounts.
TRANSMISSION OIL COOLER. Oil flowing through oil coolers on each side of engine is
cooled by air drawn in by engine cooling fans. Cooled oil flows through main oil supply
line, and flow control thermostats in coolers stop oil circulation until oil is at operating
SHIFTING CONTROLS. Shifting controlled by shift lever through system of mechanical
links to transmission shift valve that hydraulically controls transmission driving range
