TH350 Transmission Filter 3 bolt

I changed my transmission filter yesterday and it had 3 bolts going through it instead of 2 which seems to be the norm for this transmission based on how hard it was to find the same filter I took out. Does anyone else have a 3 bolt filter in a TH350 or does mine have the wrong one in it? The other thing I found odd was that you have to bend the corner of the filter up to get the pan back on. Below is a link to a picture of the filter and pan that I have.

Man I'm almost 78% sure mine had 2 bolts. Hmmm! Weird

My cousin has the same transmission and his is a 2 bolt. I ordered a 2 bolt filter off Summit before I pulled the pan down and found mine had 3. From what I found online the 2 bolt is pretty common. If mine is good the way it is then ! Otherwise I'd like to get it fixed up the right way.

All the TH-350 Ive has been 2 bolts. Never seen 3.

I'm needing one of these as well, anyone have a part number or source for just a filter?

Looks to be B&M's special filter for deep pans.

It's a b&m filter for their deep pan.

Did some more research yesterday after posting and almost positive it's the same as a Chrysler 727 filter. Will confirm after I run by napa tomorrow afternoon.

I was told once by my transmission Doctor that it was an old Chrysler filter, most likely the 727. B&M used it with their deep sump pans.

Finally got by napa and picked up the filter kit. It's a direct match. Hopefully this will save someone some head ache later on.
