Hydraulic control apparatus for an automatic transmission of a vehicle

A hydraulicly controlled automatic transmission drive train comprising:

• a hydraulic control apparatus with at least one hydraulicly actuated element that is selectively hydraulicly actuatable and connected to a separate output line;
• an automatic transmission body positioned adjacent to the hydraulic control apparatus, the automatic transmission body further comprising at least one hydraulicly controlled device having a separate input and being selectively actuated by a corresponding hydraulicly actuated element;
• and
• an interface board positioned between the hydraulic control apparatus and the automatic transmission body, the interface board being formed so that output lines of the hydraulic control apparatus match the corresponding inputs to the automatic transmission body.

A hydraulicly controlled continuously variable transmission drive train comprising:

• a hydraulic control apparatus with at least one hydraulicly actuated element that is selectively hydraulicly actuatable and connected to a separate output line;
• a continuously variable transmission body positioned adjacent to the hydraulic control apparatus and comprising at least one hydraulicly controlled device having a separate input and being selectively actuated by a corresponding hydraulicly actuated element;
• and
• an interface board positioned between the hydraulic control apparatus and the continuously variable transmission body, the interface board being formed so that output lines of the hydraulic control apparatus match the corresponding inputs to the continuously variable transmission body.

A method for producing a hydraulic control apparatus for clutches comprising:

• forming a hydraulic control apparatus with at least one hydraulicly actuated element that is selectively hydraulicly actuatable;
• connecting the at least one hydraulicly actuated element to a separate output line;
• positioning a transmission body adjacent to the hydraulic control apparatus, the transmission body having at least one control with a separate input;
• forming an interface board having openings therein that match respective positions of the output lines of the hydraulic control apparatus and the inputs of the transmission body;
• and
• positioning the interface board between the hydraulic control apparatus and the transmission body such that the openings of the interface board match respective output lines of the hydraulic control apparatus with inputs of the transmission body.
