What happens when the transfer case is not engaged?
When the transfer case is not engaged, the internal parts that turn the front wheels don’t move. One of the most typical problems with a transfer case is failure to engage. When this occurs it can indicate a problem with the transfer case. It can also be caused by a few other things.
How does a transfer case shift motor work?
Then the clutch coil is deenergized and the transfer case shift motor engages, moving the shift forks to the desired position. This is done to accelerate the front halfshafts to equal the speed of the wheels and to initiate locking of the front hubs.
What to do if your transfer case is leaking?
Without lubrication, the parts in the transfer case will quickly burn up. It’s important to repair the leak and keep the transfer case filled. It would be smart to take it in and have someone repair it if this is the case. A sure sign that the transfer case is failing is when there is difficulty shifting with it engaged.
What is the function of a transfer case?
It is best not to ignore the symptoms of transfer case issues. The function of a transfer case is to direct the power coming from the transmission to the rear wheels all the time, and the front wheels when the driver decides they need the extra traction.
How can I tell if my transfer case is working or not?
The chart at left shows the proper contact plate status for each shift motor position. If the motor is reporting the wrong position, the transfer case will not shift to the selected mode. It’s easy enough to check if the motor is working by removing it and watching it operate while an assistant works the switch.

How to monitor the 4WD vacuum control solenoid?
You can monitor the 4WD vacuum control solenoid and the 2WD solenoid status by viewing the 4WDSOL and 2WDSOL PIDs in the GEM. The solenoids also can be commanded to engage the front differential using the AXLE ENGG PID or to disengage it using the AXLE DSCN PID.
Why is transfer case not shifting to selected mode?
If the motor is reporting the wrong position, the transfer case will not shift to the selected mode. It’s easy enough to check if the motor is working by removing it and watching it operate while an assistant works the switch. These motors do malfunction on occasion and are the most common cause of the transfer case not shifting.

Why is my transfer case not working in my car?
The issue can be attributed to outside influences (e.g., a problem with the differential or driveshaft) or it might be due to an internal transfer case concern. There are many reasons why a vehicle’s 4WD system won’t engage or disengage.
Why does transfer case pop out of 4WD?
As such, some vehicles may exhibit different symptoms. Another common problem is a transfer case that pops out of 4WD. The issue can be attributed to outside influences (e.g., a problem with the differential or driveshaft) or it might be due to an internal transfer case concern.
Is it possible to replace a transfer case?
Replacement can be even more so. It is best not to ignore the symptoms of transfer case issues. The function of a transfer case is to direct the power coming from the transmission to the rear wheels all the time, and the front wheels when the driver decides they need the extra traction.
