trans pan-deep or not?

[sunliner]

how do I know if I have a deep transmission pan or not? I last changed fluid almost four years ago and due for another change....can't remember which filter I need.

I've never seen a GMT360 with a shallow pan, but easy way to make double sure is take a look at the pan. If it has a round recess toward the front and a step toward the back, it is a deep pan. Shallow is just smooth the whole way.
