I'm finally doing a fluid change for the automatic transmission in my 2002, 2-door, 4WD Blazer. I order this AC Delco filter and gasket set from RockAuto, and the gasket doesn't line up with the bolt holes. Did I order the wrong part, or did RockAuto mess up?

My oil pan is 16 bolts. The gasket is 16-bolts. But they don't line up.



The filter itself seems to be the same form factor, but it is made of a different material than the original one I pulled out. The original is a black plastic all the way around. The AC Delco replacement I ordered is aluminum on the bottom side.

 

I did a quick search on rock auto. And think the wrong one was ordered.

I put in your info, and I was not able to find the part number that you labeled. Or an acdelco one for that...

 

Actually yes I did order the wrong one. Turns out mine is considered "deep pan".
