Abstract
A gear shift failure of an automatic transmission to a wrong gear other than an indented gear is made by estimating slippage theoretically caused in a torque converter on the basis of an engine speed and a turbine speed theoretically determined for an intended gear according to the vehicle speed and comparing the estimating slippage with predetermined reference slippage. When the estimated slippage exceeds the predetermined threshold slippage, it is decided that there has occurred a wrong shift to a gear other than the intended gear.
