Beschreibung
Zusammenfassung:	A control apparatus for a vehicular transmission comprising: vehicle speed detecting means, accelerator opening angle detecting means (91); and gear-shift control means (8D). The vehicle speed detecting means includes: output shaft rotation speed detecting means (90) for detecting a rotation speed of an output shaft of the automatic transmission; road wheel rotation speed detecting means for detecting rotation speeds of road wheels (90B through 90E); and calculating means (8B) for calculating the vehicle speed from the information of the road wheel rotation speeds when a preset condition as a condition under which vertical variations of the rotation speed of the output shaft are generated is established and for calculating the vehicle speed from the output shaft rotation speed information if the preset condition is not established.
