Towing a ford transit connect? on 2013 Ford Transit Connect

If I install a tranmission pump can I tow with 4 wheels on the ground?

Asked by for the 2013 Ford Transit Connect
ford does not show towing with all 4 tires on the ground. they show using a dolly for the front wheels. not sure if installing a pump will protect the transmission or not. might ask a trans technician.
