The 41TE 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) and a cover or plug. The overdrive and underdrive accumulators are located within the transaxle case, and are retained by the valve body.

The low reverse accumulator (1) 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 (1) . 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
