1 Speed Torque on Demand Transfer Case

The 1 speed torque-on-demand system consists of the following components:

• Drive Mode Select Module
• TCCM (located near the passenger kick panel)
• IWE (integrated wheel end) solenoid (located on cowl near brake booster)
• (2) IWE vacuum actuators (one on each front hub)
• (2) IWE clutch rings (one on each front hub)
• Transfer case with high capacity clutch.
• 4WD mode indicators and messages in the IPC message center

Vehicles equipped with the 1-speed torque-on-demand system can operate in 2WD (2H), 4WD High (4H) or 4WD AUTO (4A).

The transfer case is equipped with an electronically controlled high capacity clutch which is located inside the transfer case. The clutch provides torque to the front driveline in 4WD mode.

The transfer case is shifted electronically based on the selected drive mode.

Lincoln Drive Modes allows the operator to select different drive modes. Each mode will select the appropriate transfer case mode for the terrain with no additional input from the operator.
