One output drives the front axle; the other output drives the rear axle. On most vehicles today, this torque is evenly divided as the Powertrain Control Module (PCM) sees fit. There are many inputs into the PCM that allows the PCM to split the torque in the most efficient manor and maximum traction. This method of having a computer make decisions on the torque split of the transfer case is sometimes referred to as an On-Demand - transfer case. This torque split happens seamlessly, and imperceptible to the driver…until it’s needed.

Sadly, our experience has been that most drivers don’t know if their AWD or 4X4 system is not working until they get in a driving situation where it is an imperative for the system to work. If the system doesn’t work, a stuck vehicle is often the result; and it’s never at a convenient time or place. This is why a large percentage of AWD and 4X4 transfer case system repairs end up being towed into our shop. We typically see the highest number of transfer case repairs as winter starts to set in.

The good news is that most such repairs never need a new transfer case. We have found that the most common problem with today’s transfer cases is the electronic system that operates it. Many times it is a switch, sensor, or most often, the electric shift motor to the transfer case is not working. All of these electrical problems are repairable in the vehicle, without major expense.

When transfer case problems do turn out to be more serious, it's extremely common for us to find the factory fluid still in the transfer case; few drivers know about routinely changing the transfer case lubricant. Most transfer cases require special lubricant; some, only the factory fluid will work. It takes an expert to know the difference. We’ve been fixing transfer case problems since 1973 and guaranteeing the solution to stay fixed.

If you are suspicious of a problem with your transfer case, just give us a call and we can answer your questions or set an appointment to perform a full check-up.
