Abstract
In an apparatus for controlling an automatic transmission for a vehicle in which, at the time of gear engagement due to changing over from a reverse range or a neutral range to a forward range, a speed-change stage of the automatic transmission is shifted down to a low-speed stage after once setting it to a predetermined high-speed stage. The apparatus has a detector for detecting an amount of slippage of high-speed stage engaging elements which establish the high-speed stage and a control device for controlling to shift down, at the time of gear engagement, to the low-speed stage after the amount of slippage of the high-speed stage engaging elements has lowered to a predetermined value or smaller.

An apparatus for controlling an automatic transmission for a vehicle in which, at a time of gear engagement due to changing over from a reverse range or a neutral range to a forward range, a speed-change stage of said automatic transmission is shifted down to a low-speed stage after once setting it to a predetermined high-speed stage, said apparatus comprising:
- detecting means for detecting an amount of slippage of high-speed stage engaging elements which establish the high-speed stage;
- and
- control means for controlling to shift down, at the time of gear engagement, to the low-speed stage after said amount of slippage of said high-speed stage engaging elements has lowered to a predetermined value or smaller.
