In a motor vehicle powertrain that includes a diesel engine, a particulate filter and a torque converter, a method for correcting an indicated engine output torque includes estimating a magnitude of torque being transmitted from the engine to the torque converter while regenerating the particulate filter, determining a reference magnitude of current engine torque being produced while regenerating the particulate filter, determining a torque error from a difference between the estimated magnitude and the reference magnitude, recording the torque error, determining a current torque error from the recorded torque error using a current engine speed and a current reference engine torque as indices to the recorded engine toque error, producing a corrected engine torque from the sum of the current torque error and the current reference engine torque, and using the corrected engine torque to control operation of the transmission.
