Patent ID: 11933326

Abstract:
A drop-in signal accumulator piston assembly replaces an original equipment (OE) signal accumulator piston in a vehicle transmission hydraulic circuit. The OE signal accumulator piston is positioned in a bore in a valve body that has an open end and a fluid port. The drop-in signal accumulator piston assembly includes a cylindrical sleeve having open first and second ends and a piston positioned in the sleeve. A spring is positioned in part in the piston and in part extending beyond and end of the piston. A plug is positioned in the bore adjacent the sleeve. The sleeve is positioned in the valve body bore, with the piston, and the spring, and the plug is positioned in the valve body bore to enclose the sleeve, the piston and the spring in the valve body bore. A method for replacing an original equipment (OE) signal accumulator piston in a transmission hydraulic circuit is disclosed.
