Band: Description and Operation
46RE - Automatic Transmission
BANDS / DESCRIPTION
KICKDOWN (FRONT) BAND
The kickdown, or "front", band (Fig. 78) 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. 79) 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.
