lockup clutch (p-KUB) depending on the control pressure in converter lockup clutch (p-S/KUB). See Fig. 80.

is:  

Engaged  

Disengaged  

N 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. 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).
