BANDS

DESCRIPTION

KICKDOWN (FRONT) BAND





The kickdown, or "front", band (Fig. 72) holds the common sun gear of the planetary gear sets. The front (kickdown) band is made of steel, and faced on its inner circumference with a friction-type lining. One end of the band is anchored to the transmission case, and the other is acted on with a pushing force by a servo piston. The front band is a single-wrap design (the band does not completely encompass/ wrap the drum that it holds).

LOW/REVERSE (REAR) BAND





The low/reverse band, or "rear", band (Fig. 73) is similar in appearance and operation to the front band. The rear band is also a single-wrap design (the band does not completely encompass/wrap the drum that it holds).

OPERATION
KICKDOWN (FRONT) BAND
The kickdown band holds the common sun gear of the planetary gear sets by applying and holding the front clutch retainer, which is splined to the sun gear driving shell, and in turn splined directly to the sun gear. The application of the band by the servo is typically done by an apply lever and link bar.

LOW/REVERSE (REAR) BAND
The rear band holds the rear planet carrier stationary by being mounted around and applied to the low/reverse drum.

ADJUSTMENTS ADJUSTMENT- BANDS FRONT BAND
The front (kickdown) band adjusting screw is located on the left side of the transmission case above the manual valve and throttle valve levers.
1. Raise vehicle.





2. Loosen band adjusting screw locknut (Fig. 74). Then back locknut off 3 - 5 turns. Be sure adjusting screw turns freely in case. Apply lubricant to screw threads if necessary.
3. Tighten band adjusting screw to 8 Nm (72 in. lbs.) torque with Inch Pound Torque Wrench C-3380-A, a 3-inch extension and an appropriate Torx socket.

CAUTION: If Adapter C-3705 is needed to reach the adjusting screw, tighten the screw to only 5 Nm (47 - 50 in. lbs.) torque.

4. Back off front band adjusting screw 2-7/8 turns.
5. Hold adjuster screw in position and tighten locknut to 41 Nm (30 ft. lbs.) torque.
6. Lower vehicle.

REAR BAND
The transmission oil pan must be removed for access to the rear band adjusting screw.
1. Raise vehicle.
2. Remove transmission oil pan and drain fluid.
3. Loosen band adjusting screw locknut 5-6 turns. Be sure adjusting screw turns freely in lever.





4. Tighten adjusting screw to 8 Nm (72 in. lbs.) torque (Fig. 75).
5. Back off adjusting screw 2 turns.
6. Hold adjusting screw in place and tighten locknut to 34 Nm (25 ft. lbs.) torque.
7. Position new gasket on oil pan and install pan on transmission. Tighten pan bolts to 13.6 Nm (125 in. lbs.) torque.
8. Lower vehicle and refill transmission with Mopar ATF +4, Type 9602 fluid.
