In a transmission with a countershaft and a planetary reduction gear unit, particularly for automobiles, having an input shaft (1) an output shaft (2), an intermediate shaft (23) fixed and loose pinions and gears which are in constant mesh alternately with one another and are releasably connectable to the shafts. The planetary reduction gear unit (28) comprises a ring gear (30) fixed against rotation, a sun wheel (33) driven by way of a set of pinions and gears and mounted on the intermediate shaft (23) and a planet carrier (32) connected to the output shaft. A member of a pinion-gear pair (16) is carried by the intermediate shaft (23) and is releasably connectable to the intermediate shaft (23) and the output shaft (2).
