Like the title says, which would I have? Or how can I tell so I can buy the right filter and gasket. Thanks

 

Our cars only came with one pan. Just tell them its a 97 Z28 auto and they will have the part. It is not a deep pan, I guess you could call it a shallow pan.
Enjoy removing it, and be sure and empty it b4 removing it completely to avoid a total fluid bath. It should have come with a drain plug, but did not.

 

I gave them the info on the car and they have two different ones listed. one for shallow pan one for deep pan.

 

Interesting, who is "them"?
I went to the Autozone website, and they listed one.
I just went to O'Rielly's they listed 2. Sounds like you'll have to crawl under and look. Here is their criteria:
•16 Bolt Shallow Pan
•Flat Bottom

•16 Bolt Deep Pan 2-7/8 Inch Thick, Stepped Bottom

So if you have a flat bottom (like my g/f ) you have a shallow pan.
If you have a stepped bottom, it is the deep model.
Good luck.

 

Only trucks came from the factory with deep pans... Its shallow...

 

Thanks for all the info. When I was up at Advance today and they said use dex VI. Is this what most of you use for fluid or stick with III?

As for the who Koolaid, it was advance

 

K. When you tell us where you went, it makes it easier for us to assist.
I would stick with Dex III, that's what is already in there, why change? You aren't doing a flush, so lots of Dex III is going to remain in the tranny and converter.
