Abstract

In a shift control apparatus in a vehicle automatic transmission, up-shift is carried out from a low velocity step to a high velocity step. When a rotational blow is generated, a controlling device controls the releasing side element of frictional engaging elements in such a target that the releasing side element of frictional engaging elements slips on the mating member with the engaging side element of frictional engaging elements moving for engagement.
