40TE AUTOMATIC TRANSAXLE

ACCUMULATOR

DESCRIPTION

Fig. 157 Underdrive And Overdrive Accumulators:

The 4XTE underdrive, overdrive, low/reverse, and 2/4 clutch hydraulic circuits each contain an accumulator. An accumulator typically consists of a piston (2), seal rings (3) return spring(s) (1) (Fig. 157) and a cover or plug. The overdrive and underdrive accumulators are located within the transaxle case, and are retained by the valve body

Fig.158 Low/Reverse Accumulator:

The low reverse accumulator (1) (Fig. 158) is also located within the transaxle case, but the assembly is retained by a cover and a snap-ring.

Fig.159 2/4 Accumulator Assembly:

The 2/4 accumulator is located in the valve body (1) (Fig. 159). 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 chamber against the piston and spring(s). The intended result is a smooth, firm clutch application.
