Where is the encoder motor on a GM transfer case?
Access to datastream information for GM’s NVG 246 system makes most problems simple to locate and diagnose, as our case studies demonstrate. These systems also allow bidirectional control for many outputs. The encoder motor (arrow) is mounted on the front of the transfer case and is used to lock it into 4WD.

Can a bad transmission be a transfer case?

Despite this, the symptoms of transmission failure can mimic those of a bad transfer case. This can sometimes result in confusion for vehicle owners who are attempting to fix their car themselves.
