It's a PML pan.

It was a little bit of a pain to get installed. But not as bad as most of the descriptions made it out to be. I jacked up the rear of the transmission to try and make some space to sneak the pan in there - without disconnecting the exhaust. I found that actually worked - if I carefully sneaked the pan between the exhaust and the transmission case by angling it towards the driver side - without the filter installed. Then I was able to sneak the filter in there once the pan was past the exhaust. Every other installation account I've ever read - they all said they had to drop the exhaust.
So far it's been working good. No leaks. The transmission hasn't blown itself up yet from being flushed either. It's probably had about 700 miles put on it since the flush.
