Hey guys I assume most of us know that when we are stuck we should always turn the traction control OFF. Freightliners have a button on the dash that reads "ATC", push it and it will allow the tires to spin at a faster rate. Volvo's read "TCS". Traction control is always on until the driver disengages it, after a short time and speed it will go back to traction control always being on. Don't waste your time waiting for help when this easy fix will work most of the time.
