Thanks
The A904/A500 pan gasket is P/N 4295875AC. It is used in Dakotas/Jeep XJ's.

Aviation gasket cement. Haven't had that leak in 60 years on a slew of transmissions I've changed filters in on multiple occasions.

I use either Indian Head or Aviation seal or even Hi Tack on many places but I try to avoid using anything besides a gasket on a trans pan.
Is 02464324AC a substitute? Amazon has that. If not can you suggest a good source for 02464324AD please? Does it need longer bolts than stock? I read that somewhere. Mine is overdue for replacement. Thanks in advance.

No C body "should" have a 904. As heavy of a car as they are they need the heavy duty -ness of a 727.....

All 3 of the C bodies I own have 318s and 904s.
I bet that almost all of the small block C bodies had 904s.
My question about the 904 gasket is for my A-body Barracuda.

I've rarely seen a pan leaking that loose bolts wasn't the reason.
I've lost count of the number of leaking fill tube Orings that drool into the pan rail that make it look like the pan is leaking...
Selector/kickdown shaft seals are a close second.

Are you sure that's where it's leaking?
Quite a few of the trans gasket leaks are actually leaks from the transmission shift seal and throttle link seal. That's a bit dependent on the year... Earlier transmissions with the cable shift don't have that shifter seal, but they still have the throttle linkage seal.

Could be the pan too.
I saw this the other day... (not my pic) and it's a Summit Chevy rear end cover. Note the bolt holes don't match.
Spray everything down with brake cleaner and find a BIG piece of flat cardboard to place under the oil pan, on the floor. That way, you can remove the cardboard to see exactly where the drops were coming from, rather than speculating after moving the car.
The shift shaft seal, along with the neutral safety switch can be lh side contributors. As the filler tube seal/o-ring can be from the other side of the case. In any o-ring seals, IF POSSIBLE, get the OEM part number rather than a generic o-ring from an auto supply. I went through that on the GM side of things, 45 years ago. Any o-rings need to be verified to be compatible with ATF.
After you see the location of where the drips landed, then look at those locations AND trace the fluid patch to its origination. Progress from there to repair the situation.
Please keep us posted on your progress,
