Seems pointless to just drop the pan and change the fluid in there, while leaving just as much old stuff in the T/C and cooler lines,



The important part of dropping the pan is to change the filter, clean the magnet and clean the bottom of the pan. The cooler, lines and torque converter are full of fluid but at least it's filtered fluid.

It's the same with engine oil change. Getting every last drop out of the engine is not important. Drain the bulk of it. Replace the filter and call it done.
