I'm doing some maintenance work on my 1994 7.4L 4WD 2500... I can't get a socket on the bolts at the rear of the pan because the crossbar and bushing supporting the rear of the transmission are in the way of the pan bolts. Do I really have to take the crossbar off to get the pan off to change the filter? If so what's the best way to support the transmission while I take off the crossbar?
