DISCONNECT
(1) Remove dust cap by pulling it straight back off
of quick connect fitting. (Fig. 1)
(2) Place disconnect tool Special Tool 8875A onto
transmission cooler line with the fingers of the tool
facing the quick connect fitting.
(3) Slide disconnect tool down the transmission
line and engage the fingers of the tool into the
retaining clip. When properly engaged in the clip, the
tool will fit flush against the quick connect fitting.

CONNECT
(1) Align transmission cooler line with quick con-
nect fitting while pushing straight into the fitting.
(2) Push in on transmission cooler line until a
“click” is heard or felt (Fig. 2).
(3) Slide dust cap down the transmission cooler
line and snap it over the quick connect fitting until it
is fully seated and rotates freely (Fig. 2). Dust cap
will only snap over quick connect fitting when the
transmission cooler line is properly installed.
NOTE: If dust cap will not snap into place, repeat
assembly step #2.
TRANSMISSION OIL COOLER
DESCRIPTION
The automatic transmission cooler is located in the
front of the radiator and behind the front fascia and
is conbined with the A/C condensor. The transmission
cooler is a heat exchanger that allows heat in the
transmission flud to be transferred to the air passing
over the cooler fins.
The Transmission oil cooler/A/C condenser assem-
blly is equipped with quick connect fitting for the
transmission oil cooler lines, a tapping block, for the
receiver/drier, and mounting provisions for the power
steering cooler.
The transmission oil cooler/AC condenser is ser-
viced as an assembly. For removal on vehicles
equipped with 2.4L/3.3L/3.8L engines, (Refer to 24 -
HEATING & AIR CONDITIONING/PLUMBING/A/C
CONDENSER - REMOVAL), vehicles equipped with
2.5L/2.8L engines (Refer to 24 - HEATING & AIR
CONDITIONING/PLUMBING/A/C
CONDENSER
-
REMOVAL). For installation on vehicles equipped
with 2.4L/3.3L/3.8L engines (Refer to 24 - HEATING
&
AIR
CONDITIONING/PLUMBING/A/C
CON-
DENSER - INSTALLATION), and vehicles equipped
with 2.5L/2.8L engines (Refer to 24 - HEATING &
AIR
CONDITIONING/PLUMBING/A/C
CON-
DENSER - INSTALLATION).
INSPECTION
Inspect all hoses, tubes, clamps and connections for
leaks, cracks, or damage. Replace as necessary. Use
only approved transmission oil cooler hoses that are
molded to fit the space available.
Inspect external coolers for leaks, loose mounts, or
damage. Replace as necessary.
