Enjoy 4WD With Transfer Case Service
Your four-wheel-drive (4WD) vehicle is equipped with a different transmission setup than an all-wheel-drive vehicle. If you have a true 4WD vehicle that can switch between two-wheel-drive and 4WD on demand, then you will have what is called a transfer case with your transmission.
The transfer case is engaged when the driver makes the switch from 2WD to 4WD. This is what distributes power to both the front and rear differentials to give you a true 4WD experience.
