Abstract: A transmission control device has two mutually oppositely arranged counter-components, for example control boxes, and a planar transmission control plate, which is arranged between the two counter-components. The transmission control plate seals the clearance between the two counter-components or their channel portions and bores in the form of a flat seal. The plate also provides through-openings between channels or bores, respectively, in the opposing counter-components, where the fluid in the channels controls the function of a transmission. The sealing function is realized by stamped beads and/or partial coatings. Transmission control plates therefore have fluid through-flow openings so the fluid can flow through from one side of the plate to the other side of the plate.
