Abstract
A method of draining transmission fluid through a drain hole of a transmission having an electrically driven auxiliary oil pump therein is provided. The method includes enabling, at a service computer, an oil drain service. The auxiliary oil pump is commanded on such that transmission fluid is pumped throughout the transmission and out of the drain hole. A determination is made whether the transmission fluid has sufficiently been drained out of the drain hole. The auxiliary oil pump is commanded off based on a determination that sufficient transmission fluid has been sufficiently drained out of the drain hole.
