C4 transmission pan gasket sealer

I used Indian Head schellac on my c4 transmission pan gasket. Is that ok or should I clean it off and get a new pan gasket? I peened the pan bolt holes. used straight edge on pan and it's not real straight, it has some waves in it. That's why I used the Indian Head schellac on the gasket. The pan seems to always leak, so I thought the sealer would help. Maybe my mistake and I should buy a new pan? I read that the transmission fluid would eat up the sealant and get into the transmission and cause some problems. I could use any help on this please.

The best recommendation would be to get a new pan. They are cheap enough and cost less than $10 for a stock pan. Your gonna spend half of that on silicones, etc trying to seal it. If the pan is straight you shouldn't have to use anything but a new gasket.

I wouldn't if you ever plan on changing it again. That stuff is impossible to get off once it hardens. I always use 3m weather strip adhesive to hold gaskets in place. Typically a trans pan doesn't require gasket cement.

That shellac will be dissolved by the ATF. Buy a new pan - Summit has them for about $25 and up. Another question - is the dipstick tube seal leaking? I just came up for air from working on fixing my leaky Hughes dipstick tube, which is also on a C4 - and in my car, that's a challenge.

Thanks. New pan is coming in the mail.....There is a new seal going on the dip stick tube. It wasn't leaking, just the pan. The pan has always been a problem....I was worried if the gasket sealer would come off into the transmission fluid and mess with the workings if the transmission?

You should never use any kind of sealer on any auto transmission for any reason. If you could they would do that from the factory.

Just for info... The C4 transmission came in two versions with oil pans. One model had the filler tube connecting to the oil pan itself. The older models pre 73 I know had the filler tube in the casing. There is a O ring that slips on the end that goes into the casing which
seals the tube.

Some folks still like cork gaskets but I detest cork. I tend to throw any and all cork gaskets straight in the trash. Especially trans pan gaskets. I don't recall seeing any of the nicer "reusable" rubber and steel gaskets for C4's so a "fiber" one would be what I would get. Usually the local parts store has them. Often you have to buy a "filter kit" from them just to get a gasket though.
About all transmission shops will tell you not to use any sealer at all on trans pan gaskets.

actually the early c-4's had the filler tube bolt into the pan and the later c-4's had the filler tube go down into the case.
also, with the filter kits obtained from the local parts stores, those kits normally come with a rubber gasket, not fiber.
as far as sealing of the older pans, the pan needs to be flat, and the mating surfaces need to be dry for the best chance of sealing. torque is 10-13 ft lbs.

Last three filter kits I got from Oreilly's for C4's came with fiber gaskets. I haven't seen rubber ones. Obviously other stores carry different products so those from AutoZone or someplace I don't shop may well have something entirely different. When I order C4 pan gaskets from Transtar there are only two choices, cork or fiber.

I've been using C4 transmissions in street rods since 1986 and have yet to find a rubber/steel version. Most are fiber though a few are shrunken/dried out cork - remember, this is not a production transmission nor has it been since '81, so stock doesn't move fast, if you can find gaskets at all in your local parts store. Rock Auto Parts have gaskets though.

you wont find a reuseable pan gasket for any of the old stuff. i was referring to ATP filter kits as they are widely used in many parts stores and the ATP filter kits typically come with a rubber pan gasket.

C4 Transmisison pan leaks

Had leaks all the time on 1939 ford C4, but now it is fixed. Used 11 chrome corner clamps that are used on Valve covers to prevent leaking. Bought at local Oreilly stores and fixed the problem. No leaks, no gook, just the gasket. Dont know how to insert a picture.

Now there's a good idea. Dunno how many transmission pans I've seen distorted just right around the bolt heads. Those bracket things are commonly called "load spreaders". They help quite a bit on stamped steel rocker covers, why not on a transmission pan. Good thinking.
