A gasket for automotive engine transmission, made from a cross-linking composition comprising 100 parts by weight of a polymer prepared by dissolving or swelling a noncrystalline fluoropolymer in an acrylic monomer and polymerizing the monomer, 0.1 to 100 parts by weight of a filler, and 0.1 to 10 parts by weight of a cross-linking agent. This gasket is excellent in mechanical strength and resistance to engine oil bubbling at high temperatures and also in compression set, resistances to automatic transmission fluid and long-life coolant, and durability.
