I have seen the rubber hoses for the transmission cooler feed/return get hard, crack and leak. A pump seal does seem odd for a 4EAT, especially the diagnosis with the transmission still in the car since you can's see a pump seal leak from underneath. Front shaft seal would leak and allow for fluid to leak out at the front case housing. And if that is the leak, the seal is cheap and the labor is R&R trans and an extra 20 minutes to change the seal, and cost of fluid.
Attached is a pic of a breakdown of the front housing with Torque Converter. Item 14 is the oil seal that would allow for a leak into the front case.
The other pic shows the oil pump breakdown, which is behind the front case and unseen unless the transmission is taken down and disassembled partially.
