Continuously variable transmission apparatus (12, 80) utilizing either a dual viscous clutch (86) or an impeller type hy- drodynamic torque converter (40). In one embodiment (fig. 1), the hydrodynamic torque converter (40) is operatively con- nected to an input shau (16) by intercon- nection to splitter (22), planet carrier (36) and an output shaft (18). The hydrody- namic torque converter (40) and splitter (22) is operable through a clutch assembly (38), an output planetary gear set (24) and a viscous coupling (74) between the carrier (73) and the ring gear (76) of the plane- tary gear set (24) to continuously change the speed between the input shaft (16) and output shaft (18). In the other embodiment (fig. 2), a dual stage viscous type coupling (82) is connected to the input shaft (16) through a planetary splitter (42) and to the output shaft (18) through a planetary gear set (84). The planet carrier (96) is con- nected to the sun gear (62) and the ring gear (91) in which the sun gear (62) and the ring gear (91) are viscously coupled for continuously varying the output shaft (18) rotation.
