Abstract: For motor vehicles equipped with overdrive-equipped transmissions normally biased in one of the overdrive or non-overdrive modes of operation, a method for automatically biasing the transmission (100) to the alternate mode of operation, and apparatus (10) to pratice the method. Normally used to bias transmissons (100) from the overdrive to the non-overdrive mode of operation, the apparatus (10) and method taught herein are particularly well-suited for operation in conjunction with automatic transmissions, and are actuated uniquely with each ignition run cycle. Alternatively, the method and apparatus (10) may, with equal facility, incorporate other vehicle operations and conditions to actuate its overdrive biasing function.
