Mechatronic Module

Mechatronic Module: The mechatronic module is a combination of the hydraulic valve body and electronic control module which are installed in the oil sump. This is the first time the mechatronic module is used in a BMW automatic transmission. This offers the advantages of improved stiff quality, increased driving comfort and increased reliability due to the reduced number of electrical connections and interfaces.

The hydraulic valve body contains valves, springs, dampers and electric solenoid valves. The electronic control module manages the complete electronic control of the transmission and is an integral part of the valve body (replaceable as a complete unit). The electronic control module is completely sealed and oil tight.




The electronic-hydraulic transmission gearshifts in the GA6HP26Z are controlled by 3 solenoid valves and 6 electronic pressure control valves. These components are not separately replaceable at this time.
