S-Tec ATC Transfer Case for BMW xDrive

The S-Tec ATC transfer case line is a range of rebuilt transfer case assemblies for BMW xDrive all-wheel-drive systems. The transfer case, sometimes called a transfer box or ATC unit, splits engine torque between the front and rear axles. A worn or failing unit can cause drivetrain noise, vibration, binding or xDrive warning messages. Replacing it with a rebuilt S-Tec unit helps restore proper all-wheel-drive operation.

Key Features:

• Rebuilt transfer case assembly for BMW xDrive models
• Part of the ATC transfer case family, with units offered under different ATC designations
• Designed to replace the original BMW transfer case at the matching OEM part number
• Select applications include the actuator motor, and some units come pre-filled with transfer case fluid, as documented for each part number
• Available under individual manufacturer part numbers, each cross-referenced to a BMW OEM number

Choose the part number that matches your vehicle's original transfer case designation to get a direct-fit replacement for your xDrive system.
