How do Transfer Case Shift Motors work?
As the transmission output shaft spins, splines on that shaft are turning the input shaft for the transfer case. That provides rotational power to the transfer case, which is then distributed to the output shaft by one of two sets of gears. One set of gears will drive only the rear wheels, and the other set of gears will drive only the front wheels. The rear wheels will always be connected, so the switching will only lock in the front wheels. Transfer cases have a locking function as well, and this allows the front and rear wheels to turn at the same speed regardless of the load on each wheel. Again, there is more, since many transfer cases have two speeds - hi and lo. These are typically selected electronically through a transfer case shift motor the same as four-wheel or two-wheel drive is selected. Modern transfer cases have the added benefit of torque vectoring. This function allows a percentage of power from the transmission to be sent to the front or rear wheels on demand.

What are the symptoms of a bad Transfer Case Shift Motor?
Modern vehicles with electronically shifted transfer cases will show warning lights for the transfer case, traction control, and possibly anti lock brake systems, as well as any other manufacturer specific all wheel drive system warning light. Furthermore, the switch to change the transfer case between ranges and drive modes may blink or not light up at all. This is to signal that the electronic portion of the transfer case is inactive. Lastly, the transfer case may be stuck in one drive mode and/or drive range, or switch between these ranges without request from the driver.
Can I drive with a bad Transfer Case Shift Motor?
Since the transfer case is essential to drive, any failure resulting in inability to operate the vehicle normally will require immediate repair. In some cases, the transfer case shift motor can be disconnected to prevent erratic shifting, but if another drive mode is needed, it will be unavailable.
How often do Transfer Case Shift Motors need replacement?
Transfer case shift motors in some makes and models are known for frequent failure, even in the first 50,000 miles. However, this is not typical, especially when shifting procedures from the manufacturer are followed. This is the best way to help the transfer case shift motor continue operation.
