Abstract

A transmission hydraulic control system with a bracket mounted solenoid is provided which reduces leakage by providing a direct interface between a solenoid sleeve and a valve body that doesn't require high precision cartridge and valve body cylindrical bore machining. Simpler flat surface machining replaces the bore cartridge geometry to provide a solenoid interface. A hold down bracket secures the solenoid valve in position on the valve body.
