A transmission control unit for a wedge clutch, comprising a controller configured to send one or more signals to a switch connected to the wedge clutch, the switch being configured to demagnetize the wedge clutch by sending current in a first direction to a coil of the wedge clutch.

Method for controlling electromagnetic wedge clutch

An arrangement for a multi-clutch assembly including a popoff valve is disclosed. The arrangement also includes a first clutch, a second clutch, and a spool valve assembly. Depending on the mode, the popoff valve either provides a flowpath for residual hydraulic fluid from a latching chamber of the spool valve assembly to a vent of the popoff valve, or provides a flowpath for supplying hydraulic fluid to the latching chamber of the spool valve assembly via a fluid connection from a supply inlet to a latch port of the popoff valve.
