    摘要: A clutch piston assembly increases the clamping pressure within a transmission or torque converter, without increasing the oil pressure, in order to reduce the slippage of the clutches against the reaction plates and has a piston housing that receives a cylinder bore ring atop of which is seated a cylinder bore. The cylinder bore has a series of progressively wider inner grooves with the uppermost groove being the widest yet substantially narrower than either of the cylinder bore ring's grooves, thereby decreasing the overall apply area of the central bore thereby increasing the clamping pressure that can be exerted by the clutch piston assembly.

    摘要: A torque converter stator has interchangeable blades and has a body member with a central hub and an annular wall. Dovetail openings are located on an outer surface of the annular wall. Each blade has a dovetail pin that is removably received within a respective one of the dovetail openings. A cover plate is removably attached to the body member in order to secure the blades in place within their respective dovetail openings. A heated duct ring is positioned over the outer ends of the blades and allowed to heat shrink into contact with these ends as the duct ring cools and shrinks, thereby securing the duct ring to the remainder of the stator.
