<p>A method is described for controlling a powertrain of a vehicle. In particular, the method attempts to minimize transmission gear separation, or "clunk". Under some circumstances, it is determined whether torque converter output speed has become greater than torque converter input speed while the torque converter was unlocked. Such a situation represents a change from positive powertrain output to negative powertrain output. If such a situation has occurred, under certain circumstances, the torque converter is then locked.</p> |
