Abstract

A vehicle includes a transmission and a controller. The transmission has clutches that are configured to establish multiple speed ratios, including a first clutch. The first clutch has a measured drag torque distribution. The measured drag torque distribution has a median and a standard deviation. The controller is programmed to increase a pressure at a rate to engage the first clutch and to increase the rate in response to a measured first clutch torque exceeding the median by a predetermined multiple of the standard deviation.
