Lubricates and cools the mechanical part of the transmission, and limits the pressure in the torque 
converter. 

Lubrication Pressure Regulating Valve, Function 
 
See LUBRICATION PRESSURE REGULATING VALVE, FUNCTION.  

Lubrication Pressure Regulating Valve, Function 

Operation - At the working pressure regulating valve (22) surplus oil is diverted to the lubrication pressure 
regulating valve (23), from were the lubrication pressure (p-Sm) is used in regulating amounts to supply the 
transmission lubrication system including the torque converter. See Fig. 76

Overlap Regulating Valve, Location 
 
Each shift group is assigned one overlap regulating valve. The 1-2/4-5 overlap regulating valve (30a) is 
installed in the valve housing of the shift plate (2b), the 2-3 overlap regulating valve (30b) and 4-5 (30c) 
are installed in the valve housing of the shift plate (2a). See Fig. 77

Overlap Regulating Valve, Location 
 
The overlap regulating valve regulates the pressure reduction during a shift phase. 

Overlap Regulating Valve, Function

Overlap Regulating Valve, Function 

Operation - During the shift phase the pressure in the disengaging shift actuator is controlled depending on the 
engine load (modulating pressure (p-Mod)) and the pressure in the engaging shift actuator. The regulated 
pressure is inversely proportional to the transfer capacity of the activating shift actuator (regulated overlap). See 
Fig. 78
