Abstract
Herein disclosed is a transaxle casing to be used with a transverse type automatic transmission. An arcuate partition extending from the top to the bottom of a transmission gear case is disposed between the radially outermost rotary member of the transmission gear seat and a cover wall and in front of the transmission gear set with respect to the running direction of a vehicle. An oil sump is disposed below the transmission gear set. Thus, the lubricating oil splashed away the rotary member is guided into an oil return passage extending between the partition and the cover wall and opening into the oil sump so that it may be prevented from being caught again by the transmission gear set and heated to a high temperature.
