A transmission comprising a main change speed mechanism, an auxiliary change speed mechanism, a rear differential mechanism and a cassette type supplementary change speed mechanism. The supplementary change speed mechanism acts on the transmission through an opening defined in a transmission case housing the transmission. The supplementary change speed mechanism is housed in and supported by a supplementary change speed case which is attached to the transmission case. Transmissions of various specifications may be provided by making various types of supplementary change speed mechanism. The supplementary change speed mechanism is applicable to a propelling transmission line and/or a power takeoff transmission line. |
