ABSTRACT:
An automatic transmission with an anti-creep control apparatus includes a torque converter connected to the engine, first and second friction elements, and a control unit. The first friction element is operated when the automatic transmission is put in a drive range. The second friction element performs to prevent a reverse rotation of an output shaft of the automatic transmission. The control unit executes an anti-creep control controls, controlling the second friction element to prevent a reverse rotation of an output shaft of the automatic transmission when the anti-creep control is executed, holds the engagement of the second friction element during a time period from the time when the anti-creep control is cancelled to the time when the first friction element is fully engaged, and disengages the second friction element thereafter.
