I buy the preminum Victor gasket that has the tin foil sandwiched in between the 2 corks outters. I do not use a sealer ( but I do lightly smear wheel bearing grease on both sides )

I do not have any problems with leaking. This may or MAY NOT be the correct way ... but it is the way I have done it for 20 years or more.

Maybe Crosley will answer this question ... he is the transmission professional here

I'm like Deuce, only cork gaskets for me, but I don't want anything on them, install bone dry on a absolutely oil-free clean case surface and flat dry clean pan rail. No sealers, and this is the procedure given to me by my race trans builder 20 years ago. It's always worked for me. The fiber/rubber gaskets I've had no luck with at all.

Be nice if they made a 1 piece silicone rubber gasket with the steel ring imbedded at every bolt hole to prevent crushing, like the 1-piece engine oil pan gaskets...anyone know if they do??

Most builders like the Duraprene gaskets, They're a little sticky, it helps hold them in place during assembly and reusable. They're Black or Brown, fine fiber material.

Seems to me a 2006 pontiac g 6 had one. Fords have been using them for a while.
Rubber ones are useless as most covers are to flimsy to seal it without deforming, ultimatley leaking anyhow.
Cork is the one I like . I torque them and use blue loctite to keep the bolts from backing out and causing a leak.
I was told years ago to never use anything on a trans pan as trans fluid will eat it anyhow and it gets into everything(clutch packs ) and can cause undesirable opertion characteristics.
That may be why they put those holes that "grab" the bolts into the pan gaskets(cork) as the holes are smaller than the bolts

the 4t60E/65E has had a reuseable pan gasket for several years now, as well as other gm models, ford and chrysler have also done the same. they all are a bit different from each other, but the end result is that they work over and over again. i think theyre great and should be made for all models.
i grew up that used nothing but cork and it works rather well, but with technology, i like the fiber gaskets, you can run them down and not have to go back and retorque them, like cork because after initial torque and then being run, the cork will "seat" and will need to be gone back over.
we use cork gaskets and after every final test drive, i go back over the pan bolts. always get about 1/2 turn with a speed handle..

I use gorilla snot (3M yellow weatherstrip cement) to hold the gasket to the pan, installed dry on trans case side.

All that's needed is to run the bolts through the gasket and pan from the gasket side to hold it in alignment while the glue sets up some. Otherwise, I have a hell of a time getting the gasket to 'behave'- they always seem to be folded up into the box in such a way as to make them VERY hard to deal with. For me, anyways.

A properly installed gasket will never need any sort of sealent.

When people install the pans people usually torque to much causing the bolt hole to distort. so take a flat punch and set the pan on a flat surface and peen the holes.
dont just tighten the bolts, find the proper torque specs, and tighten the bolts like you would a cylinder head.

So that would be 120 to 144 inch lbs ,so I should be OK at 130--that's what an old Chilton book I have says,but someone told me that GM's specs say 94 for a cork gasket

I've had zero problems on a TH350 with a rubber gasket on an alum cast pan, tightened to 100 inch-pounds, no sealants used.

I have cork gasket retardation. I always under torque or overtorque and they leak

Unless its a cast pan, then cork works pretty well for me without sealant. I like to get the steel/rubber gaskets. That way you can't squish them out, the steel limits the possibilty of overtorquing/bending the flange.
