1K of engine torque will equal several times that at the differential. You have to multiply the trans gear ratio X the diff ratio, then multiply that times the engine torque. Then double that number, as the torque converter can double the amount of torque.
For instance, a Dana 70 is rated for 7000 ft-lbs of torque. I broke 3 teeth on my Dana 70 trying to pass a car. Under torque, the differential case will actually flex, so you loose gear mesh, which in turn breaks teeth.
