Abstract
In a control apparatus for an automatic transmission having multiple speeds constituted by four sets and speed selecting mechanisms corresponding to the four sets, assuming the speeds as seven among eight speeds of A to H in order of gear ratio, the four sets are constituted by a first set of A having a largest gear ratio and C that is next but one; a second set including at least H having a smallest gear ratio; a third set of B and D between two of the first set; and a fourth set including two of E, F and G between the second and third sets, and one of first and second pressure regulators selectively supplies hydraulic pressure to two of the mechanisms corresponding to the first and second sets, while the other thereof selectively supplies hydraulic pressure to two of the mechanisms corresponding to the third and fourth sets.
