Abstract:
1. A clutch accumulator assembly for replacement of an original equipment clutch accumulator assembly of an automatic transmission, wherein the original equipment clutch accumulator assembly comprises an accumulator piston having a cylindrical sidewall being disposed in a mating bore within a valve body of the transmission, an accumulator pin extending through a central bore in the accumulator piston and defining a pin/piston interface, said pin being secured within a hole in the valve body located along the center axis of said mating bore, a seal ring radially disposed about the accumulator piston, a compression spring disposed within the piston, and an accumulator cover securing the clutch accumulator assembly within the valve body of the transmission, said clutch accumulator assembly comprising: a modified accumulator piston having a solid radial web structure wherein the the pin/piston interface is eliminated; piston sealing means installed on said modified accumulator piston for sealing said accumulator piston within its mating bore; piston guiding means installed on said modified accumulator piston for guiding the reciprocating movement of said modified accumulator piston during operation; a compression spring disposed in coaxial relation to said accumulator piston; and plugging means for insertion within the hole in the mating bore in substitution of said accumulator pin.
