F4A33 for 2WD and W4A33 for AWD, I do not know the OEM part # but I know the part # of the company name AXIOM,
http://www.axiom.com/atc/site/locations/locations.aspx they have all all parts that you need including the torque converters. if you can't get it from these locations tell the sellnam to call the Reman Facility in Hard Part Division and they will fix you up.
