FLUID
STANDARD PROCEDURE - FLUID DRAIN AND
REFILL
The fill and drain plugs are both in the rear case
(Fig. 70).
(1) Raise vehicle.
(2) Position drain pan under transfer case.
(3) Remove drain and fill plugs and drain lubri-
cant completely.
(4) Install drain plug. Tighten plug to 41-54 N·m
(30-40 ft. lbs.).
(5) Remove drain pan.
(6) Fill transfer case to bottom edge of fill plug
opening with Mopar
t ATF +4, type 9602, Automatic
Transmission fluid.
(7) Install and tighten fill plug to 41-54 N·m
(30-40 ft. lbs.).
(8) Lower vehicle.
FRONT OUTPUT SHAFT SEAL
REMOVAL
(1) Raise vehicle.
(2) Remove front propeller shaft. (Refer to 3 - DIF-
FERENTIAL & DRIVELINE/PROPELLER SHAFT/
PROPELLER SHAFT - REMOVAL)
(3) Remove front output shaft companion flange.
(4) Remove seal from front case with suitable pry
tool (Fig. 71).
INSTALLATION
(1) Install new front output seal in front case with
Installer Tool 8143-A as follows:
(a) Place new seal on tool. Garter spring on seal
goes toward interior of case.
(b) Start seal in bore with light taps from ham-
mer (Fig. 72). Once seal is started, continue tap-
ping seal into bore until installer tool seats against
case.
(2) Install the front output shaft companion flange.
Tighten the flange nut to 122-176 N·m (90-130
ft.lbs.).
(3) Install the front propeller shaft. (Refer to 3 -

MODE SENSOR
DESCRIPTION
The transfer case mode sensor (Fig. 73) is an elec-
tronic device whose output can be interpreted to indi-
cate the shift motor shaft’s rotary position. The
sensor consists of a magnetic ring and four Hall
Effect Transistors to create a 4 channel digital device
(non-contacting) whose output converts the motor
shaft position into a coded signal. The TCCM must
supply 5VDC (+/- 0.5v) to the sensor and monitor the
shift motor position. The four channels are denoted
A, B, C, and D. The sensor is mechanically linked to
the shaft of the cam which causes the transfer case
shifting. The mode sensor draws less than 53 mA.
OPERATION
During normal vehicle operation, the Transfer Case
Control Module (TCCM) monitors the mode sensor
outputs at least every 250 (+/-50) milliseconds when
the shift motor is stationary and 400 microseconds
when the shift motor is active. A mode sensor signal
between 3.8 Volts and 0.8 Volts is considered to be
undefined.
Refer to for the relative angles of the transfer case
shift sector versus the interpreted transfer case gear
operating mode. Refer to for the sensor codes
returned to the TCCM for each transfer case mode
sensor position. The various between gears positions
can also be referred as the transfer case’s coarse
position. These coarse positions come into play dur-
ing shift attempts.
