The invention relates to a lubrication system for a gearbox (1 ) in a vehicle, such that the gearbox (1 ) comprises a gearbox housing (2), an input shaft (3), an output shaft (4), a countershaft (5) and a number of gearwheels (8, 9, 10, 13, 14, 15, 16, 17, 18) and the lubrication system comprises an oil sump (6) which is situated in the gearbox housing (2) and a container (7) which is intended for temporary storage of lubricating oil and is situated above said oil sump (6). According to the invention, said container (7) is provided with an aperture (19) which faces substantially away from the oil sump (6), which container (7) is intended to be able via said aperture (19) to capture oil which splashes in the gearbox (1 ) when the vehicle's longitudinal axis (A) is parallel to a horizontal plane, and that said container (7) is so arranged that at least part of the oil in it is allowed to run back from the container (7) to the oil sump (6) via said aperture (19) by force of gravity when the vehicle's longitudinal axis (A) is at an angle to said horizontal plane. The invention relates also to a gearbox (1 ) which comprises a lubrication system according to the present invention.
