Ok, I need to change the gasket on my 727 transmission pan. I used cork before, with some sort of blue RTV. I'm not sure that it ever stopped leaking! A dribble here & a dribble there. What do you suggest? I have a rubber gasket. But I'm used to cork. If I use the rubber gasket, what RTV should I use? I'm temped to use cork again, but with Permatex 2. Putting the gasket on the pan & letting it dry overnight. Then applying the same sealant with a dab on each screw... Any help would be greatly appreciated. Thanks! Tim...

As long as the pan-rail is straight and flat ...and you do NOT over-torque the bolts .... ......ANY gaskets will work. I have a cork one on my 62 since the late-70's ... on and off maybe 8 or so times .....NO problem. And NOTE ... if you are chancing STRIPPING the threads in the case by OVERtightening ... you are using about FIVE TIMES ++ ... tooooo much torque on these bolts.

Go to a Dodge/Chrysler dealer and get the newer style reuseable pan gasket. The number for the 727 (or A-518/46RH/46RE) is: 2464324AC. It is hard nylon over steel with molded in double sealing beads. Be careful not to overtorque it, or you can strip the case threads because it doesn't compress the same as a cork or rubber gasket.
One of the best things I ever did. I love mine. It is a slightly different shape than a 727 pan from Mopar (old, or even their deep pan -- P3690730AB) but it seals and seals well. I agree with the torque issue too. I think the book calls for something like 150inlbs which is too much for cork too. I went to around 1/2 that.

I just rebuilt a GM (yeah I know ) but I re-used a rubber one that we had put on several weeks earlier when we thought it might just need a fluid and filter change. I got a new on in the kit but it was cork and as simply a personal choice, I'm not fond of cork. Anyway, point is, I just used a little film of white grease but no sealer. I go just snug on all bolts and another wrist twist (1/4 to 1/3 turn?) Been two weeks now and no leaks. If you can see the gasket compress and squish out any, you've over tightened.

x2..x3...x4 on the newer pan gasket from the dealer well worth the $ just dont over torque the pan bolts,the gasket does not crush and you can strip the threds very ez if you do pull some threds out..you can usally get by with a longer bolt as the newer gasket is thicker had mine 5 yrs now and on/off about 8x so far and still no leak at the pan rail now the shift selector seal is another thing though

Don't use rtv. Use Indian shellac or some thing else, or get one of those rubber/steel insert gaskets. RTV can get small blobs gunked up into everything, use a painted on type sealer.
I agee i just did my pan and used Indian head and a rubber gasket fixed the prblem.

Great stuff till you want to take it apart for a trans service. Have fun. The new ribbed gaskets seal with no added sealer and are reusable.

I've always 3m adhesive a cork gasket [after it relaxes] to the tranny pan and then bolt it up, no sealer in the trans side. the 3m works great. mainly you need a pan that has not been torq'd to death in the past.

Make sure your pan is flat on the mating area. A lot of the time you will see that in the bolt hole area that they are bowl shaped, this is from over tightening. Check with a straight edge on the surface that mates to the housing and see if everything is flush. If not you can work the bolt holes in the opposite direction to get a good seal on install.

Ok, since I posted last, I've had several gaskets on the tranny pan and it is still leaking... I even got the one from the Chrysler dealer, and that one leaked also. I also checked the flatness of the pan, it is fine. It is a deep pan. The good thing is that I'm getting pretty good at dropping it. Luckily, it has a plug for drainage. Ok, I'm beginning to think that perhaps it is leaking at the filler tube. I'm going to check that today. But here is my question... It only appears to leak when it is sitting (I know, otherwise I wouldn't notice it...duh!). But I'm wondering if perhaps I'm overfilling it. The filler tube is NOT original. Does the fluid sitting in the pan normally lie ABOVE the seal between the pan and tranny? That is, perhaps when the car is sitting the fluid is supposed to be below the pan lip. Anyone??
