Are you sure it's coming from the pan? When the truck sits, fluid drains out of the converter into the body of the trans. If it still has the original style o-ring seal on the trans dipstick, I would bet that is your leak. Also, a little bit of trans fluid will cover a lot of ground- it creeps everywhere.

120 ft-lb seems a little excessive for a torque spec. I would bet that is 120 in.-lb
