(5) If the turning torque is within specifications,
remove tools. Setup is complete.
(6) If turning torque is not within specifications
proceed with the following steps to obtain proper
shim selection:
(a) Remove differential bearing retainer from
the transaxle case.
(b) Remove the bearing cup from the differential
bearing retainer using Tool 6062A.
(c) Remove the existing shim from under the
cup.
(d) Measure the existing shim.
NOTE: If the turning torque was too high when
measured, install a 0.05 mm (0.002 inch) thinner
shim. If the turning torque is was too low, install a
0.05 mm (0.002 inch) thicker shim. Repeat until 5 to
18 inch-pounds turning torque is obtained. Refer to
the “Differential Bearing Shim Chart.” Oil Baffle is
not required when making shim selection.
(e) Install the proper shim under the bearing
cup. Make sure the oil baffle is installed properly
in the bearing retainer, below the bearing shim
and cup.
(f) Install the differential bearing cup, shim, and
oil baffle using Tool 5052 and C-4171. Seal the
retainer to the housing with MOPARt Silicone
Rubber Adhesive Sealant and torque bolts to 28
N·m (250 in. lbs.).

torque should be within 5–18 in. lbs.
GOVERNOR
DESCRIPTION
The governor assembly is fastened to the transaxle
transfer shaft. It consists of a governor body, weight,
valve, and shaft.
OPERATION
The governor meters hydraulic pressure, and this
metered pressure is used to signal the transmission
when it is time for a shift to occur. It does this by
balancing governor pressure on one side of a shift
valve, and throttle pressure on the other. When gov-
ernor pressure increases far enough to overcome the
throttle pressure on the valve, a shift occurs.
With the gearshift selector in a forward driving
range, line pressure flows from the manual valve and
down to the governor valve. When the output shaft
starts to rotate with vehicle motion, the governor
