O'Reilly Power Torque Converter Question

Alright, update time. I called around and no one cleans them in-house. One shop that I've used in the past, and trust, can get a Precision converter for a dang good price, and it's in a local warehouse. The only downside is they are an hour and a half away, and I need to bring the old one with me so they can be absolutely sure to order the correct one (lots of possibilities on a 727). Good news is, they can get it same day!
