    Abstract: A method of selectively matching at least one diameter of a valve spool or piston of a spool valve to at least one diameter of a valve bore in an automatic transmission valve body reduces hydraulic fluid leakage in the valve body. The method includes the steps of fabricating a spool valve having at least one spool or piston, measuring a diameter of the at least one spool or piston and identifying the spool valve as belonging to certain size class, fabricating a valve body having a plurality of machined bores, measuring the diameter of at least one portion of a bore and, based on this measurement, installing a spool valve of the appropriate size class in the bore of the valve body.

    Abstract: A solenoid assembly is disposed in a bore of a valve body where the bore includes a plurality of ports. The solenoid assembly includes a bushing or sleeve disposed in the bore. The sleeve has at least one slot that is aligned with at least one of the plurality of ports. A valve is slidably disposed within the sleeve. A solenoid has a movable armature configured to move the valve.

    Abstract: A transmission includes an input drive shaft, a drive gear, an idler gear, and a driven gear. The drive gear is rotationally fixed to the input drive shaft which, in turn, may but not necessarily, be powered by an engine. The idler gear may include a second set of gear teeth mounted to a bearing wherein the second set of gear teeth are formed from polymeric material. The second set of gear teeth for the idler gear may be in meshing engagement with the first set of gear teeth. The driven gear may include a third set of gear teeth in meshing engagement with the second set of gear teeth. The driven gear may be rotationally fixed to a pump shaft for a transmission pump. The input drive shaft, the drive gear, the idler gear, and the driven gear are configured to power a transmission pump.

    Abstract: An active thermal hydraulic control system for a transmission is provided. The active thermal hydraulic control system improves fuel economy by storing transmission fluid in areas away from rotating components during hot operation. However, during other conditions the transmission fluid is kept in the sump. The active thermal hydraulic control system includes an active thermal valve. The active thermal valve is an electro-mechanical device which converts electrical energy into thermal energy which melts a wax pellet which in turn moves a plunger. Movement of the plunger controls the opening and closing of a valve that communicates between the sump and the side or front cover of the transmission. The system improves fuel economy by as much as 0.5% by storing excess hydraulic fluid away from rotating components.
