Jeep Cherokee (XJ): Transmission cooler. Brake transmission shift interlock mechanism
DESCRIPTION MAIN COOLER The transmission main cooler is located in the
radiator. The main cooler can be flushed when necessary,
however, the cooler is not a repairable component.
If the cooler is damaged, plugged, or leaking,
the radiator will have to be replaced. AUXILIARY COOLER The auxiliary cooler is mounted in front of the
radiator at the driver side of the vehicle (Fig. 36).
The cooler can be flushed when necessary, while
mounted in the vehicle. The cooler can also be
removed for access, repair, or replacement as needed.
The main and auxiliary coolers should both be
flushed whenever a transmission or converter clutch malfunction generates
sludge, debris, or particles of
clutch friction material.
1 - COOLER INLET LINE COOLER SERVICE The main cooler (and radiator) and the auxiliary
cooler can be removed for service or access to other
components. Auxiliary cooler removal requires that
the front bumper and radiator support be removed
for access to the cooler lines and attaching bracket. DESCRIPTION The Brake Transmission Shifter/Ignition Interlock
(BTSI), is a cable and solenoid operated system. It
interconnects the automatic transmission floor
mounted shifter to the steering column ignition
switch (Fig. 37). OPERATION The system locks the shifter into the PARK position.
The Interlock system is engaged whenever the
ignition switch is in the LOCK or ACCESSORY position.
An additional electrically activated feature will
prevent shifting out of the PARK position unless the
brake pedal is depressed at least one-half an inch. A
magnetic holding device in line with the park/brake
interlock cable is energized when the ignition is in
the RUN position. When the key is in the RUN position
and the brake pedal is depressed, the shifter is
unlocked and will move into any position. The interlock
system also prevents the ignition switch from
being turned to the LOCK or ACCESSORY position
(Fig. 38) unless the shifter is fully locked into the
PARK position. 1 - SHIFT MECHANISM

Inspect the connecting rod bearings for scoring and
bent alignment tabs (Fig. 28) (Fig. 29). Check the
bearings for normal wear patterns, scoring, grooving,
fatigue and pitting (Fig. 30). Replace any bearing
that shows abnormal wear.
