Ratio Control Motor
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2007 MINI Cooper, 2006 MINI Cooper, 2005 MINI Cooper, 2004 MINI Cooper, and 2003 MINI Cooper. However, it is still accessible from the selected car via links, so may be relevant.
The Ratio Control Motor is housed inside the transmission, adjacent to the oil cooler pipe connections. The motor and solenoids are connected to the main harness via a circular connector. The motor is operational in all transmission modes and controls the hydraulic control unit to adjust the primary pulley to the appropriate position. The motor which controls the transmission ratio is a linear actuator and a bi-polar stepper motor.
