I had replaced my transmission fluid a few weeks ago and had checked my pan to make sure it was straight which it was. I could not find a gasket at 4 different parts stores but I could get the filter, I ended up using right stuff gasket maker. Ran a double bead 1/4" each around the pan and circled each bolt hole. After 2 weeks, I have noticed a large leak coming out of 2 driver side pan bolts. I have watched it while it was running after wiping everything down with a rag. I am a little hesitant to just remove the 2 bolts and run some locktite or Teflon cause I'm afraid it will start pouring out like crazy after removing them. Any ideas on why they're leaking now?

I had a gasket I got in my filter kit, but I noticed it had a tear in it when I went to install it, and needed to get back on the road. Went to orielly's, napa, auto zone, and advanced auto and none of them had a filter kit for a 727 I couldn't believe it.

Worse case if you cannot find this gasket at parts houses check with you local Dodge dealership if there is one still left? The 727 was used in all types of vehicles thru the 70's including motorhomes. You can also check online with a company by the name of MagHytec for some trick aftermarket pans with a reusable gasket and a drain plug for easy service in the future...

So I went to a dodge dealer and they can't find a non-paper gasket in their books. But I found a Parts Master transmission filter set for $8 that has a Fel-Pro "Fel-CoPrene" in it. Flexible rubber gasket seems like it'll work. Now, the service manual says to torque the pan bolts to 150 in/lbs, which is way too much for a paper gasket but do you think it will be fine for this rubber one?
You know what I've been wondering since your first post; why did the right stuff give up at only two bolt locations? And, both on the driver side too. Reason I'm asking is if you applied the sealer in an even coat and didn't over torque the bolts, squeezing all of it out; it shouldn't have failed anywhere. Is there any possibility that your leak isn't really coming from the pan bolts at all but is coming from the kick down servo, ruining down the side and ends up looking like it's two bolt holes, or adjacent pan? There are two seals in there that will fail. There is also the neutral safety switch in that general area which can leak also.
I'd almost suggest getting a leak detection kit and verifying the source of the leak before dropping that pan again. They're kind of expensive but, as many leaks as you can come across on a Scout, they definitely aren't a one time use tool. I got one similar to this one a few years ago. It has dyes for a/c. oil and coolant so, you can have all kinds of fluorescent fun: LINK BRD RACING

I had wiped the whole transmission down and laid under it with it running. That's when I noticed fluid collecting around those 2 bolts, and then dripping off the rim of the pan. I may still throw some dye in it, because I have used right stuff gasket maker before on transmissions and never had this issue.
