Im needing some clarification on where a specific gasket is located on the transmission for a 2003 Acura TL Type-S. In image with number and diagram I want to know where Passage body gasket (#25) is located. It looks like it’s where the ATF warmer is at but underneath or under the assembly but that’s just my assumption. I’m currently doing a swap on my Acura Trans and see the leak is coming from under neath the ATF warmer I have replaced both o-rings for ATF warmer but get a leak. If anyone can provide some insight and or clarification it would be

Reason: Title update
Your assumption is correct. You are looking at the ATF passage body in one of the pictures above. It is the flat plate where the ATF filter is attached / located.
One of the bolts is clearly shown, just find the other two, remove, replace gasket, re-install?
Purple arrow indicates the #25 passage body gasket.
