Abstract
A method for manufacturing a carrier assembly of a stacked planetary gear set is provided. The method includes forming the inner and outer spiders and attaching the spiders to a back plate or to each other to form the carrier assembly. One or both of the inner and outer carrier spiders are formed from powdered metal, by precision casting, and/or by stamping. The stacked planetary gear set may be axially aligned or axially offset.
