Abstract

An automatic transmission including a continuously variable transmission, a friction type starting apparatus and a forward and reverse changeover apparatus, comprises a sealed clutch housing rotating integrally with an engine output shaft for accommodating the friction type starting clutch and the forward and reverse changeover apparatus therein, a lubricating oil filled up in the clutch housing for cooling the starting clutch and the forward and reverse changeover apparatus and a clutch drum of the starting clutch integrally formed with the clutch housing, thereby an abrupt temperature rise in the starting clutch can be prevented and the durability of the starting clutch can be substantially improved. Further, since the friction type starting clutch and the forward and reverse changeover apparatus are packaged in the sealed clutch housing, a compact automatic transmission can be realized.
