Most shops are going to want to run one of those flush machines on it and not even pull the pan. There can be a lot of metal dust and black stuff in the pan, it needs to be pulled and cleaned.
I agree also, I would pull the torque converter plug. Do you have a aux oil cooler in front of the radiator? If not, that would be more beneficial than a deeper pan on the trans.
