Which filter is right?

[east302]

Truck is a 1998 K1500 (3/98 build date) with the 4l60e. I’m changing the fluid and ordered Delco/GM filter 24208576 which is on the top. That’s the one they sell for the deep pan.

It’s the same height as the one that I pulled (on the bottom) but it’s longer and doesn’t have the ribs on it.

So the pan hits the filter when putting it back on. The previous owner said the transmission had been rebuilt but so much shoddy work was done that I have no idea.

Does this look like a shallow filter with a deep pan? I can barely get this filter into the seal (which I replaced). Feels like I need to pound it into place so I stopped. I rubbed the filter neck with transmission fluid but it seems like it shouldn’t take that much effort.

Any suggestions?

Edit: I’m an idiot, just didn’t have the filter seated up far enough. It fits fine, I’d delete the thread but can’t figure out how.

Did you get the old filter seal out? Most of the time they stick up in the transmission and have to be fished out.

EDIT: Doh! Reading comprehension fail. You fixed it.

Lol, thanks for chiming in. Spent an hour trying to pry that stupid seal out and gave up before I sent a hammer through the windshield.

Bought a slide hammer blind hole puller and got it out in less than a minute. The filter just needed a tap with a rubber mallet to seat.

Most folks inspect that seal in the pump for the filter neck; if it's in good condition--not cut or torn--they just leave the original seal in place.

Yeah, it became a “I wish I had just left this thing alone” moment fairly quickly. The seal probably could have stayed put and been fine.

Yep, that was me also the first time opening any transmission drain pan to change a filter.

Was cussing after bending that little filter a few times with a flathead screwdriver....and the tranny was on my workbench, LOL.

I've since watched videos where they use a heavy u-shaped pick. A firm tap with a hammer and seal is out...takes literally like 1 second!

Just make sure you do not scratch the pump bore. Given that the pump is aluminum, this would be fairly easy.

To answer another ? you mentioned.

The old filter is a shallow and the pan is a deep

But the new plastic filter is correct for the deep pan

Is only the deep pan stepped, or is this characteristic of all 4L60e pans? Only ones that I have experience with are the 2 99 Burbs. Thanks!

Deep pan is stepped. I’ve read that transmissions built after 10/1997 was the changeover. I have another 98 model (9/97 build date) and it has the flat shallow pan.
