Abstract
An off-axis transmission pump is driven via an idler gear. To reduce the transmission of gear noise, the idler gear is supported by a plastic cover. The plastic cover includes a molded-in metal insert to harden the cover in the vicinity of the idler gear. The metal insert may include inner and outer sleeves which may be connected by radially extending arms. The plastic cover is located relative to a front cover by at least two locating features.
