Shift Valve Pressure, Function 

Operation  

The shift valve pressure is derived from the regulating valve pressure, regulated at the shift valve pressure 
regulating valve and is then present:  



1-2 And 4-5 Shift Solenoid Valve (Y3/6Y3)  



3-4 Shift Solenoid Valve (Y3/6Y4)  



2-3 Shift Solenoid Valve (Y3/6Y5)  



Torque Converter Lockup PWM Solenoid Valve (Y3/6Y6)  



3-4 And 2-3 Shift Pressure Valve Shift Valve  

The shift valve pressure controls the command valves via the upshift/downshift solenoid valves.

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. 138. 

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

Shift Pressure Shift Valve, Location 
 
Each shift group possesses one shift pressure shift valve. The 1-2/4-5 shift pressure shift valves (29a) and 
2-3 shift pressure shift valve (29b) are installed in the valve housing of the shift plate (2b), the 3-4 shift 
pressure shift valve (29c) is installed in the valve housing of the shift plate (2a). See Fig. 139. 

Shift Pressure Shift Valve, Task 
 
To assign shift pressure to the engaging shift actuator and to assign the overlap pressure, controlled by the 
overlap regulating valve, to the disengaging shift actuator.
