GF27.60-P-5213ACM Overlap regulating valve, component description
- TRANSMISSION 722.643/649
- refinement package
- as of model year 09

Component Identification:

Location
An overlap regulating valve is assigned to each shift group. The 1 - 2 or 4 - 5 overlap regulating valve is installed in the valve body of the valve body assembly, the 2 - 3 and 3 - 4 overlap regulating valves are installed in the valve housing of the valve body assembly.

Task
The overlap regulating valve regulates the pressure reduction during a shift phase.





Function
During the shift phase the pressure in the disengaging actuator is regulated depending on the modulating pressure (engine load) as well as on the pressure in the engaging actuator. The regulated compression is inversely proportional to the transmission capability of the engaging actuator (regulated overlap).
