1 - PULLEY RATIO LINKAGE

2 - STEPPER MOTOR

3 - RATIO CONTROL VALVE

4 - LINE PRESSURE

5 - SECONDARY VALVE

6 - SECONDARY PULLEY

7 - PRIMARY PULLEY

The pulley ratio linkage moves to the left direction of the stepper motor. The line pressure circuit opens due to the movement of the ratio control valve which links to the pulley linkage, and line pressure is applied to the primary pulley.

The secondary valve moves to open and fluid in the secondary pulley is drained while maintaining the pulley pressure.
