The PG transmission on the '55 leaks, while sitting in the drive way...Really have to keep an eye on the fluid level....Its not the burb through the fill tube thing, its something else.....I haven't investigated it yet.

Before I crawl under there and start looking, are there places that typically leak that I should look at....I'm thinking line connections, tail shaft seal and worse case front pump seal The transmission seems to be operating just fine by the way.

Any help will be greatly appreciated

BUMP!

The usual place for it to leak is the front pump seal, which will leak out through the hole in the bell housing, apart from gaskets.
Either way if it is the seal the box needs to come out.

That's what I was afraid of.....Since its performing well, I plan on nursing it along, until I get a TH700-R4 in her.

Does the stop leak junk made for transmissions do any good or will it just plug up the inner passages of the transmissions as well?

There is no magic in a can but some products offer some benefits. My old Powerglide was leaking pretty badly (don’t they all?). It had been sitting for a long time before I got her and I suspect the seals had dried out. I tried Lucas Transmission fix and much to my surprise the leaks stopped (well almost stopped) and she would shift into low from high much smoother. If you are going to replace the transmission regardless, it is worth a shot. It is supposed to expand the seals and not clog anything up.

(As a personal comment from experience I would never use a transmission flush on an old automatic transmission unless it is in preparation for a rebuild.)

David, I think he means filler tube O-ring on the right side and shifter seal on the left side.

This is why I have not used my 56 convertible in 2 years. I resealed it once 20 years ago and it needs it again. The usual culprit is the sealing ring (actually a "quad" ring) between the converter housing and the converter cover. I have the parts just can't seem to find the time.
