ACCUMULATOR
DESCRIPTION
The 42RLE underdrive, overdrive, low/reverse, and
2/4 clutch hydraulic circuits each contain an accumu-
lator. An accumulator typically consists of a piston,
return spring(s), and a cover or plug. The overdrive (1)
and underdrive (2) accumulators are located within the
transmission case, and are retained by the valve body.
The low reverse (1) accumulator is also located within
the transmission case, but the assembly is retained by
a cover and a snap-ring.
The 2/4 accumulator (5) is located in the valve body. It
is retained by a cover and retaining screws.

OPERATION
The function of an accumulator is to cushion the application of a frictional clutch element. When pressurized fluid is
applied to a clutch circuit, the application force is dampened by fluid collecting in the respective accumulator cham-
ber against the piston and springs. The intended result is a smooth, firm clutch application.

BEARINGS
ADJUSTMENTS
BEARING ADJUSTMENT PROCEDURES
Take extreme care when removing and installing bearing cups and cones. Use only an arbor press for installa-
tion, as a hammer may not properly align the bearing cup or cone. Burrs or nicks on the bearing seat will give a
false end play reading, while gauging for proper shims. Improperly seated bearing cup and cones are subject to
low-mileage failure.
Bearing cups and cones should be replaced if they show signs of pitting or heat distress.
If distress is seen on either the cup or bearing rollers, both cup and cone must be replaced.
NOTE: Bearing drag torque specifications must be maintained to avoid premature bearing failures.
Used (original) bearing may lose up to 50 percent of the original drag torque after break-in.
NOTE: All bearing adjustments must be made with no other component interference or gear inter-mesh.
Oil all bearings before checking turning torque.
