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 direction 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 transmission hydraulic control relief valve. The oil flow is divided in the transmission hydraulic control relief valve. The torque converter and the clutch solenoid modulating valves receive the oil flow that is divided. The torque converter inlet relief valve limits the oil pressure to the torque converter to a maximum pressure of 900 70 kPa (130 10 psi).The torque converter outlet pressure is 414 34 kPa (60 5 psi).Torque Converter Outlet Relief Valve

Illustration 3 g03353695The torque converter outlet relief valve controls the minimum pressure in the torque converter. When the pressure in the torque converter falls below 414 34 kPa (60 5 psi), the force of spring (1) moves spool (2) to the right in order to limit oil flow to the oil cooler.The outlet relief valve is mounted to the right side of the torque converter cover.Spacers (3) are used to adjust the closing pressure of the relief valve.
