A common sump supplies oil for the manual transaxle. When the manual transaxle is operating normally, the differential assembly, together with 1st and 2nd gears, splash oil from the sump to oil pockets in the transaxle case. From these pockets, oil travels into channels in the input and output shafts and lubricates all gear bearings. Reverse gear has its own lubrication system. First gear splashes oil into a pocket in the clutch housing. From there, oil travels through the reverse idler gear shaft to lubricate the reverse gear components.
