ACCUMULATOR

DESCRIPTION

The 4XTE 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
and underdrive accumulators are located within the
transaxle case, and are retained by the valve body
(Fig. 164).

The low reverse accumulator (Fig. 165) is also

located within the transaxle case, but the assembly is
retained by a cover and a snap-ring.

The 2/4 accumulator is located in the valve body. It

is retained by a cover and retaining screws (Fig.
166).

OPERATION

The function of an accumulator is to cushion the

application of a frictional clutch element. When pres-
surized fluid is applied to a clutch circuit, the appli-
cation force is dampened by fluid collecting in the
respective accumulator chamber against the piston
and spring(s). The intended result is a smooth, firm
clutch application.

DRIVING CLUTCHES

DESCRIPTION

Three hydraulically applied input clutches are used

to drive planetary components. The underdrive, over-
drive, and reverse clutches are considered input
clutches and are contained within the input clutch
assembly (Fig. 167). The input clutch assembly also
contains:

• Input shaft

• Input hub

• Clutch retainer

• Underdrive piston

• Overdrive/reverse piston

• Overdrive hub

• Underdrive hub

OPERATION

The three input clutches are responsible for driving

different components of the planetary geartrain.
