Abstract
A method of rebuilding a pressure control solenoid includes uncrimping a housing of the solenoid, and disassembling the solenoid. An original spool valve of the solenoid is removed from a hydraulic bore of the solenoid. The hydraulic bore is reamed such that an inner diameter of the bore is enlarged. A replacement spool valve is inserted into the hydraulic bore. An outer diameter of the replacement spool valve is larger than an outer diameter of the original spool valve.
