(20) Lube relief valve
(21) Temperature sensor The transmission is controlled and lubricated by oil that is supplied from the sump (15) of the power train hydraulic system by power train oil pump (13).Oil is taken from the sump of the hydraulic system by the oil pump and oil is fed via oil filter (11) and oil filter (17) to the following components:
Modulating Valve (Torque Converter Lockup Clutch)
Modulating Valves (Electronic Clutch Pressure Control)
Transmission Hydraulic Control Relief Valve
Torque ConverterTest points for oil pressure and two oil temperature sensors are incorporated in the hydraulic system.Control of the planetary transmission is achieved by electronically activated modulating valves (19) that allow oil to fill the various clutches in the planetary transmission.Torque converter (4) allows the power to be transmitted smoothly from the engine to the planetary transmission. The torque converter allows the speeds of the engine and the transmission to be matched smoothly. Once the speeds are matched, the modulating valve for the torque converter lockup clutch (9) engages the clutch in the torque converter. The torque converter provides direct drive from the engine to the planetary transmission.Oil is fed to the torque converter and the oil transmits the drive from the engine to the planetary transmission. Outlet oil from the torque converter goes to the oil cooler and forward via relief valve (20) as lubricant for the transmission.
