Lubrication System For The Transmission
LUBRICATION SYSTEM SCHEMATIC
1. Oil screen. 2. Lubrication relief valve. 3. Hydraulic controls. 4. Oil pump. 5. Torque converter. 6. Transmission reservoir. 7. Oil cooler.The oil that is necessary for the operation and lubrication of the transmission is made available by oil pump (4). The gear that drives the pump (4) is fastened to the impeller housing of the torque converter (5) and turns at engine speed. The rotation of the pump is one and one half of engine speed.The oil reservoir (6) for the transmission is in the bottom of the transmission case. The oil is pulled through a screen (1) by the pump (4). The pump oil goes to the hydraulic controls (3).Valves in the hydraulic controls (3) send oil to the clutches in the transmission and to the torque converter (5). Oil from the torque converter goes through the oil cooler (7) and then through the lubrication relief valve (2) to the reservoir (6).
