Torque Converter (1) Rotating housing. (2) Impeller. (3) Gear. (4) Inlet port. (5) Output shaft. (6) Turbine. (7) Stator. (8) Adapter. (9) Carrier assembly. (10) Outlet port.The torque converter is located at the input end of the transmission. The torque converter housing is bolted to the flywheel housing. Output torque from the torque converter enters the planetary transmission through either the Number 1 sun gear or the Number 2 sun gear. The gear that receives the output is dependent upon the directional clutch that is engaged.Oil for the operation of the torque converter is supplied by the transmission oil pump. Oil from the transmission oil pump flows to the torque converter housing. The oil flow is divided in the torque converter housing. Oil flows to the transmission hydraulic control relief valve and the transmission modulating solenoid valves. The transmission hydraulic control relief valve allows P3 converter inlet oil to flow to the torque converter at a nominal pressure of 550 kPa (80 psi). The torque converter inlet relief valve limits the oil flow to the torque converter to a maximum pressure of 900 70 kPa (130 10 psi). The torque converter inlet relief valve is located in the torque converter housing beneath the transmission hydraulic control relief valve.The torque converter outlet pressure is 415 kPa (60 psi).Rotating housing
