The electrically variable transmission family of the present invention provides low-content, low-cost electrically variable transmission mechanisms including first and second differential gear sets, a battery, two electric machines serving interchangeably as motors or generators, and up to five selectable torque-transfer devices, and a dog clutch. The drilling tool drills the port hole to size in a solid material for the minor thread diameter in combination with forming the port in a single operation. The reservoir is in fluid communication with the nozzle.
