HOLDING CLUTCHES
DESCRIPTION
Two hydraulically applied multi-disc clutches are
used to hold planetary geartrain components station-
ary while the input clutches drive others. The 2/4
and Low/Reverse clutches are considered holding
clutches and are contained at the rear of the trans-
mission case (Fig. 156).

OPERATION

NOTE: (Refer to 21 - TRANSMISSION/AUTOMATIC -
42RLE - DIAGNOSIS AND TESTING) for a collective
view of which clutch elements are applied at each
position of the selector lever.
2/4 CLUTCH
The 2/4 clutch is hydraulically applied in second
and fourth gears by pressurized fluid against the 2/4
clutch piston. When the 2/4 clutch is applied, the
front sun gear assembly is held or grounded to the
transmission case.
LOW/REVERSE CLUTCH
The Low/Reverse clutch is hydraulically applied in
park, reverse, neutral, and first gears by pressurized
fluid against the Low/Reverse clutch piston. When
the Low/Reverse clutch is applied, the front planet
carrier/rear annulus assembly is held or grounded to
the transmission case.
