WARNING: This page is about a different car, the 2019 Ford F-550 Super Duty, 2019 Ford F-450 Super Duty, 2019 Ford F-350 Super Duty, and 2019 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
The MSOS 4WD system consists of the following components:
- Manual shift lever
- Transfer case assembly
- Manual front wheel hub locks
The Manual Shift-On-Stop transfer case is a 2-piece aluminum design. The transfer case transfers engine power from the transmission to the front and rear axles. Vehicles equipped with the Manual Shift-On-Stop system allow the operator to choose between 2WD and 2 different 4WD modes. The MSOS 4WD system is engaged or disengaged by rotating the control for both front wheel hub locks from the FREE or LOCK position, then manually engaging or disengaging the transfer case with the floor-mounted shifter.
