2-Speed Torque-On-Demand Transfer Case
WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The 2-speed torque-on-demand system consists of the following components:
- ATCM
- TCCM (located near the passenger kick panel)
- IWE (one on each front hub)
- 4WD mode indicators and messages in the IPC message center
- Transfer case with shift motor and high capacity clutch
Vehicles equipped with the 2-speed torque-on-demand system can operate in 2WD (2H), 4WD AUTO (4A), 4WD High (4H), or 4WD Low (4L). When shifting into or out of 4WD Low (4L) range, the TCCM requires that the vehicle speed is less than 5 km/h (3 mph) and the transmission is in NEUTRAL.
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 all 4WD modes.
