Lock-up System

Lock-up Clutch

1. Operation (clutch on)

With the lock-up clutch on, fluid in the chamber between the converter cover and lock-up piston is discharged, and the

converter fluid exerts pressure through the piston against the converter cover. As a result, the converter turbine is locked

on the converter cover firmly. This bypasses the converter, placing the vehicle in direct drive.

2. Operation (clutch off)

With the lock-up clutch off, fluid flows in the reverse of CLUTCH ON. As a result, the lock-up piston moves away from the

converter cover, and the torque converter lock-up is released.
