Abstract

A low profile electric pump arrangement having a motor housing connected to a pump element of a transmission for a vehicle. An inverter housing connected to the motor housing and has a where an electronics control unit (ECU) connects through the inverter housing to selectively supply power to the motor within the motor housing. The recess and the ECU are covered and sealed off from the elements by a plastic cover. In order to obtain a low profile of the electric pump arrangement so it can fit within a desired packaging line on a transmission casing a metal bracket is over molded into the plastic cover. The metal bracket has at least one exposed surface that engages the inverter housing to hold the plastic cover onto the inverter housing in a position so that the plastic cover covers and seals the ECU and recess at the second side of the inverter housing.
