The Getrag 288 5-speed transaxle is a constant-mesh transaxle that is synchronized in all gear ranges. See Fig 1.

The transaxle consists of four major sub-assemblies: the input shaft (4), output shaft (5), reverse shaft (3), and integral differential assembly (6). The transaxle is of a split-case design, utilizing a geartrain housing (1) and clutch housing (2) to contain as well as support the geartrain via a combination of roller and needle bearings.

The transaxle shift system consists of a mechanical shift mechanism, shift rails and forks, and gear shift cables. The unique design of this shift system provides a higher mechanical advantage, resulting in less friction and lower shift cable loads for smoother, more positive operation.
