In a transmission series different versions of lubricant supply pumps have a uniformly designed and dimensioned coupling pin between lubricant supply pump and transmission drive shaft or take-off shaft. In addition different versions of lubricant supply pumps have a uniformly designed and dimensioned mechanical interface on their drive shaft-side housing end face side. This mechanical interface includes a centering shoulder radially surrounding the coupling pin and a circle of holes concentric to the centering shoulder provided with threaded holes for attachment screws on the drive shaft-side end face side of the lubricant supply pump.
