ABSTRACT:
The present invention provides a method for controlling the partial frictional engagement between the torque converter and the vehicle engine called "partial lock-up" mode of operation to reduce the rotational speed difference between torque converter and the engine. The present invention eliminates surges that occur for partial lock-up which may result in a harsh shift.
