Post subject:  1964 A body 904 Gaskets

So, it's been a few hours since I asked a dumb question. Here's another one. I've got a transmission that's leaking like a sieve when I pour fluid into it. I can watch about half of what I pour seep out below filler on the right side of the transmission. It's been about ten years since I've had the transmission serviced, and it's definitely due for a gasket change or two. I looked up the parts on Rock Auto and the only gasket they had for my car was this one:

FEL-PRO Part # TOS18583 {Automatic Transmission Gasket}
14-bolt holes; Chrysler A727 3 Spd. Automatic Transmission

I'm pretty sure "A727" means it's not for a 904 unless... (here's the dumb question) Did they use the same gasket? Napa is coming up with nothing, as is autozone.

I know the cable shift 904s were different than the later models. Would one of their gaskets work?

Thanks for any help you can offer.

ETA: Or, I guess I could just buy this off eBay.

The 904 vs 727 have different pan gaskets.
The filter kit you want should be listed as 64-65, 904 Torqueflite and it should contain a filter with 2 oil feed holes.

An FYI... I recently used a 66 and up 904 filter kit on a 64 and had to add the second (rear pump) oil feed hole to the filter.
I matched the holes location to the old filter, poked-into the fiber filter skin and found that the cut-out for the second hole was already in the filter's metal subframe.
I snipped away the skin with small scissors, following the edge of the under-laying subframe hole... it took about a minute to do the modification.

One other thought, check to see if your leak is from the o-ring on the dipstick tube, that is the other "leak point" on the passenger side of a 904.

Thanks, Doug. It's entirely possible that it was the dipstick tube given the location it seemed to be coming from. I'll check that out as well.

Dipstick tube is likely culprit. You can either get an o-ring, or just pull it and goop it with permatex, which is what I always do.

Hmm. Permatex sounds like a good option. Thanks, Lou!

Dipstick is probably the culprit given the location of the leak. See this post for info on gasket and filter selection.

Thanks, Dan! Those part numbers are just what I needed!
