The present invention solves bore wear due to inefficient design of OEM pressure regulator valve through an improved pressure regulator valve with lands having narrower diameters and longer lengths, the lands additionally having a grooved design, and a second land having a beveled edge to stabilize fluid regulation. Narrower lands allow for better ATF lubrication in a bore. Longer lands allow for the valve to be dropped into a bore to interact with non-damaged lengths of the bore without further machining. The beveled edge regulates pressure, further reducing bore wear.

A motor control method for a shift-by-wire system recognizes a current position of a switched reluctance (SR) motor at a point in time when a shifting request is input as a start position and determines whether the current position of the SR motor is the same as a target position, applies a current for rotating the SR motor toward the target position when the current position and the target position are not the same, counts time until a point in time when an actual motion of the SR motor is sensed, performs advanced-angle control of increasing a rotation speed of the SR motor when the counted time exceeds the time reference value, and measures a current applied to the SR motor and increases the advanced-angle control or performs retarded-angle control of decreasing the rotation speed of the SR motor, depending on the measured current value.

A system and method for an automotive transmission includes one or more restrictor devices that are installed within a valve body of the automotive transmission to improve performance by establishing a flow limit along the compensator circuit. The complex fluid circuits of certain automotive transmissions having eight to ten speeds allow line pressure supply to bleed out during certain critical functions, such as low rotations per minute hot engagements, which can severely damage the transmission. By limiting flow, the line pressure supply can be preserved to prevent the compensator circuit from bleeding out in these critical functions. The instant invention limits flow by replacing the standard compensator valve with a compensator valve that has a larger spool diameter. Flow is further reduce by another restriction device placed along the compensator circuit between the compensator valve and the clutch drums.
