G288 MANUAL TRANSAXLE

DESCRIPTION

The Getrag 288 5-speed transaxle (Fig. 2) is a con-

stant-mesh transaxle that is synchronized in all gear
ranges.

The transaxle consists of four major sub-assem-

blies: the input shaft, output shaft, reverse shaft, and
integral differential assembly. The transaxle is of a
split-case design, utilizing a transaxle housing and
clutch housing to contain as well as support the
geartrain via a combination of roller and needle bear-
ings.

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 pro-
vides a higher mechanical advantage, resulting in
less friction and lower shift cable loads for smoother,
more positive operation. The shift pattern is shown
in (Fig. 1).

The Getrag 288 transaxle is available with the

2.2L Turbo Diesel and 2.4L Turbo Engine options. Its
gear ratios are as follows:

TRANSAXLE IDENTIFICATION

The transaxle identification label is found on

clutch housing, near the differential cavity (Fig. 3).
The label consists of the transaxle part number, as
well a 12-digit engine identifier/build date code (Fig.
4). Digits 1-3 are the identifier (TCG = 2.2L Turbo
Diesel — TBU = 2.4L Turbo). Digits 4-6 represent the
day of year built. The 7th digit represents the calen-
dar year of build, and the remaining 5 digits are the
build sequence number. For example, a transaxle
with the identifier “TCG114100003” is considered to
be the 3rd transaxle built on the 114th day of the
year 2001, and goes behind the 2.2L Turbo Diesel.

OPERATION

NEUTRAL

Engine power is transmitted to the input shaft via

the clutch assembly and the input shaft turns. Since
no synchronizers are engaged on either the input or
output shafts, power is not transmitted to the output
shaft and the differential does not turn (Fig. 5).
