(1) Torque converter, pulled unit, brake, and transmission hydraulic tank (2) Torque converter, pulled unit, and brake section (3) Transmission sectionThe torque converter, pulled unit, brake, and transmission hydraulic tank (1) is located on the outside of the right side of the frame. The transmission section (3) is separated from the torque converter, pulled unit, and brake section (2) by a wall inside the hydraulic tank (1). The transmission section (3) supplies oil for the operation of the transmission. The torque converter, pulled unit, and brake section (2) supplies oil to the brakes, to the brake cooling system, to the torque converter system, and to the pulled unit. An air breather for section (2) and an air breather for section (3) are located on the vertical frame member on the right side of the truck.The torque converter, pulled unit, and brake section (2) has two sight gauges. The top sight gauge is generally used for checking the oil level. The bottom sight gauge can be used when the pulled unit hydraulics are in the OPEN position. The transmission section (3) also has two sight gauges. The bottom sight gauge is used for checking the oil level with cold oil. The top sight gauge is used for checking the oil level with hot oil. See the Operation and Maintenance Manual for lubrication viscosities and for refill capacities for both sections of the hydraulic tank.Tank Ports
