All I do is make sure both surfaces are free of oil, use a clean rag and brake cleaner. Apply the RTV to one surface, let it set up for 10 mins or so or until it becomes tacky. Install cover and tighten. Your all done!
Just becareful when you lay the bead that you don't get it to close to the bolt holes. You don't want the sealer going in the holes as if there blind, it will hydrolock the bolts and they will snap or pull out the threads!
Mike, like they say, "cleanliness is next to godliness" be sure you get all the oil off the faces. I usually use brakekleen (I get the AutoZone generic). Make sure it is not the "envioronmentally friendly" type, that won't work. I have use the Mechanix brand from Advance with good results (my son calls it cheese whiz). Make sure the cover is flat, if not you can "reverse dimple" the bolt holes so the plate portion pulls down tight. Put a small (1/8" or so) bead on the transaxle face, going inside the bolt holes as you pass them. Carefully install the cover and start at least 2 bolts on opposite sides. If you have the bobble strut studs you can use them to keep one side aligned. Alternately tighten the bolts/studs until you have them all tight, use a torque wrench and follow Ma Mopar's values. Good luck, it should work unless you have owned a british car, then you are cursed to spend all eternity fighting electrical gremlins and mystery leaks.
In case it doesn't work ... what I've always done is #1 to stop the oozing, I'll let the jack go way down to drain a whole bunch of the fluid out, and then jack it way up high. It works pretty well. Clean it up well, then apply RTV to both the tranny case AND the cover. You can make sure it adheres to the metal pretty well that way, rub it in well with your finger. Then stick the cover on, and you're good!
No way, :bang head, :blah: You must have a porous casting or its coming from somewhere else. I do it the way I told you with all my customers cars and they never leak! I have even done A413 tranny pan when I didn't get sent a gasket late at night with ATF dripping and it still seals!!!!!
Check the driver side diff carrier seal. I've had them seep and the ATF "crawls" along the case to the lowest point of the trans (under the diff cover). Clean the area REAL good and spray some old-man deodorant or baby powder on the case. If it is higher up than the actual diff cover, you'll see it running down through the deodorant/powder.
Mike, maybe you actully have a Harley, they don't leak, just mark their spot. Seriously, the other source or porous casting does sound likely. If you find it is a porous casting, you can probably fix it inplace. You will have to get all the fluid out, then clean the inside of the porous area completely. Use J-B weld and smooth it carefully over the inside where the fluid seems to be coming from. Wait 24 hrs, reassemble the cover, pray to the appropriate deities and hope for the best. Good luck this time.
