Hydraulics Fundamentals: Accumulators & Shift Feel
As electronics came into play, solenoids were added to the accumulator circuits, giving better control to the shift feel based on driving conditions, thereby eliminating the need for some valves. In many newer 6- and 8-speed transmissions, "traditional" accumulators and related valves are no longer needed.

A hydraulic accumulator is a part of a hydraulic system that stores the energy created by the pressure on the hydraulic fluids. Hydraulic accumulators are used as pressure storage reservoirs. They contain hydraulic fluid, and this fluid is pressurized with an external source.
Contact UsHydraulic Accumulators
Charge these accumulators to the pressure you need, and they will help a system maintain a constant pressure during pump failure. Mount them in any orientation. UN/UNF (SAE Straight) thread connections have straight threads and are also known as O-ring Boss fittings.. Note: For safety, do not disassemble accumulators while they''re under pressure.
