How does the transfer case shift motor work?
How does the transfer case shift motor work?
The four-wheel drive (4WD) control module controls the transfer case shift motor that shifts between 4WD HIGH, 4WD LOW, and 2WD modes. The 4WD control module accomplishes shifts by interpreting inputs from the following:
Can a transfer case be changed in a 4WD truck?
The entire motor can be replaced, or just the less expensive encoder inside can be changed. The transfer case encoder motor moves the transfer case selector automatically. In Auto 4WD, it continually moves the input shaft of the transfer case to vary the amount of torque that goes to the front driveshaft.
How does the transfer case control module work?
As you already know, the TCCM controls the shifting in the 4WD system. But, how does it do that? The module determines the processing of the shift by using the speed of the vehicle and the real-time transfer case mode. if the shift is possible, the TCCM will complete it by activating the transfer case encoder motor.
Why is my transfer case not moving properly?
If the transfer case won’t go to the proper position, or behaves erratically, it could be the encoder inside the encoder motor. If it does not move at all, it could be the motor itself. The entire motor can be replaced, or just the less expensive encoder inside can be changed.

Are there lights on the transfer case selector switch?
Service 4wd and no lights… the lights on the transfer case selector switch in the dash no longer comes on. it does flash when turning the key to start the truck, but it remains in two wheel drive. Ive changed the selector switch, but that did not work.
Is there any way to test the transfer case?
If a new shift motor assembly must be installed, it will be necessary to shift the transfer case to the AWD position prior to motor installation. Raise the vehicle on a suitable hoist.Remove the front propeller shaft.
