Automatic Torque Coupling (ATC) Solenoid

WARNING: This page is about a different car, the 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.

The Automatic Torque Coupling (ATC) solenoid is integral to the Rear Drive Unit (RDU), and applies clutch pressure as controlled by the AWD relay module to increase or decrease torque to the rear wheels. The Rear Drive Unit (RDU) transfers torque from the drive shaft to the rear wheels depending on the specific request from the FWD system module (PCM). The Rear Drive Unit (RDU) and Automatic Torque Coupling (ATC) solenoid are serviced in Chassis, Driveline article. Refer to: Axle Assembly .
