摘要：
A method of regulating operation of an automatic transmission includes identifying a tie-up condition of the automatic transmission, adjusting a pressure of a transmission element in response to the tie-up condition and determining whether a first gear ratio of the automatic transmission holds. The pressure is set to zero if the gear ratio does not hold and a faulty transmission element is identified as one associated with a second gear ratio that is lower than said first gear ratio.
