GF27.60-P-5123-01G Torque Converter Lockup Clutch Regulating Valve, Function

GF27.60-P-5123-01G Torque converter lockup clutch regulating valve, function
- TRANSMISSION 722.6





Operation
The converter lockup clutch regulating valve (27) regulates the working pressure in the converter lockup clutch (p-KUB) depending on the control pressure in the converter lockup clutch (p-S/KUB).

Depending on the working pressure in the converter lockup clutch (p-KUB) the converter lockup clutch (KUB) is:
^ Engaged
^ Disengaged
^ in slip mode

In the lower position of the converter lockup clutch regulating valve (27) lubricating oil (p-Sm) flows through the torque converter and oil cooler (65) into the transmission (converter lockup clutch depressurized). In its regulating position (slipping, torque converter lockup clutch pressurized), a reduced volume of lubricating oil (p-Sm) flows through the annular passage (27a) bypassing the torque converter and passing direct through the oil cooler (65) into the transmission. 65 The other part of the lubricating oil (p-Sm) is led via the restrictor (a) into the torque converter for cooling the converter lockup clutch (KUB).
