Disclosed is a control apparatus for a vehicular transmission comprising: a vehicle speed sensor; an accelerator opening angle sensor; and a gear-shift control section (8D) of a CVTECU 8. The vehicle speed sensor includes: an output shaft rotation speed sensor (90) configured to detect a rotation speed (rotation numbers) of an output shaft (41) of the automatic transmission; road wheel rotation speed sensors configured to detect rotation speeds (rotation numbers) of four road wheels (90B through 90E); and a vehicle speed calculating section (8B) of CVTECU 8 configured to calculate the vehicle speed from the information of the road wheel rotation speeds when a preset predetermined condition as a condition under which vertical variations of the rotation speed of the output shaft are generated is established and calculate the vehicle speed from the output shaft rotation speed information if the predetermined condition is not established.
