How does the transfer case work on a Ford Explorer?
How does the transfer case work on a Ford Explorer?
The Control-Trac transfer case uses an electromechanical clutch assembly to control torque to the front wheels. In the Auto mode, while at rest and under cruising conditions, the 4×4 electronic module activates the transfer case clutch at a minimum level.
What happens when the transfer case output shaft fails?
If this happens, the transfer case will be rendered useless and the four-wheel drive operation will not work. Over time the transfer case output shaft seal can fail, and when it does, will display a few symptoms that will alert the driver that a problem with this system exists.
Where is the transfer case shift motor located?
The externally mounted transfer case shift motor, located at the rear of the transfer case, turns the shift cam assembly. As the shift cam assembly turns, it positions the reduction shift fork for desired transfer case operation. An integral position sensor in the shift motor provides motor position information to the 4×4 electronic module.
What happens if there is a leak in a transfer case?
Clearly, without any fluid in there, the problem will go from bad to worse. 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.

Where is the push button 4×4 transfer case switch?
An integral position sensor in the shift motor provides motor position information to the 4×4 electronic module. Switch, Push Button 4×4 Mode. The push button 4×4 mode switch, mounted on the instrument panel, allows the operator to select the 4×4 Auto, 4×4 High, and 4×4 Low transfer case operating modes.

What’s the 4×4 mode on a Ford Explorer?
The push button 4×4 mode switch, mounted on the instrument panel, allows the operator to select the 4×4 Auto, 4×4 High, and 4×4 Low transfer case operating modes. The indicator light, on the instrument cluster push button, will illuminate only when the 4×4 Low position is engaged.
Where is the DTR sensor on a Ford Explorer?
The DTR sensor completes the start circuit in PARK and NEUTRAL, the back-up lamp circuit in REVERSE and the neutral sense circuit (4WD) in NEUTRAL. The DTR sensor also sends a digital output signal to the powertrain control module (PCM) indicating the manual lever position (P, R, N, D, 2, 1). The TP sensor is located on the throttle body.
