A transfer includes: an input shaft; an output shaft; a high-low switching mechanism; an output member whose output destination is different from output destination of the output shaft; a clutch for transmitting a power to the output member; a first transmitting mechanism for transmitting movement of an internally threaded member to the clutch; and a drum cam having a cam groove. The cam groove includes a first inclined section that causes the high-low switching mechanism to be switched between a high-speed gear stage and a low-speed gear stage, and a second inclined section that causes the first transmitting mechanism to be switched between (i) a separated position in which the first transmitting mechanism is separated from the clutch and (ii) a contact position in which the first transmitting mechanism is in contact with the clutch, while the high-speed gear stage is established in the high-low switching mechanism.

A method for forming a component utilizing ultra-high strength steel and components formed by the method. The method includes the step of providing a flat blank of ultra-high strength 22MnB5 steel. The next step of the method is, cold forming the flat blank into an unfinished shape of a component while the blank is in an unhardened state. The method continues by providing an inert atmosphere. Then, heating the unfinished shape of the component in the inert atmosphere. The method proceeds by forming a finished shape of the component using a quenching die resulting in a fine-grained martensitic component material structure and enabling net shape processing to establish fmal geometric dimensions of the components.

A dog clutch for an automatic transmission includes a mating clutch that defines a plurality of helical splines and a sliding clutch that defines a plurality of helical splines. The helical splines of the sliding clutch mesh with the helical splines of the mating clutch in an engaged configuration. The dog clutch also includes a synchronizer positioned at the sliding clutch. A related automatic transmission is also provided.

An automotive driveline component has a housing and a shipping cap. The automotive driveline component can be a component of a power transfer unit (PTU), a final drive unit (FDU), a rear drive module (RDM), or a drive shaft. The housing has a wall that partly or more defines an opening. The opening is open to an exterior of the housing when the automotive driveline component is in an uninstalled state. The shipping cap can be temporarily secured in the opening. The shipping cap has a liquid collector for precluding residual lubricant in the housing from pooling at the opening. The liquid collector can be in the form of a sump, an absorbent material, or both.
