Motor, Shift: Operation: Operation
WARNING: This page is about a different car, the 2015 RAM 3500 HD and 2015 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
The transfer case shift motor responds to the Drive Train Control Module (DTCM) commands to move the transfer case shift range fork, as required, to obtain the correct transfer case operating range indicated by the instrument panel mounted selector switch. The motor only shifts between 1:1 ranges, 2.64:1 range, and neutral. Switch changes between 2WD, 4WD LO and 4WD HI are assisted by the transfer case coil.
