OK, I threw a roach down after the fly.  Seems the roach did more damage than the fly as I have another leak.  Maybe the pan leak was hiding the other leak(s).  I'm gonna take a guess at the cable adjust seal.  I'll clean everything even better tomorrow and check it out after a ride.  Hopefully this won't interfere with the CAC/NCM trip...I leave this Thursday.

The pan held some sizable chunks.  Looked like scale rust about the size of quarter of a dime(2.5 cents worth).  May have been from the pan itself(?), there were a couple of rusted areas on the pan.  Cleaned everything up before re-installing.  Painted the pan white...looks ridiculous but that was the only heat resistant paint I had left.

Dadgummit....Cry
BEst to clean all around as much as you can, drive it some, and check to see if you can find the source. If it is a small leak, then it shouldn't be an issue for your trip(s), as long as you keep an eye on the fluid level.  Only three places it can leak on the driver side, and that's from the selector shaft seal(shifter), the electrical connector for the lock-up converter, and the governor cover.
On the passenger side, there's quite a few places it can leak. Cooler lines, filler tube seal, TV cable seal, the accumulator cover, and the modulator.
Then of course you have you major issue leaks...from the FRONT area...you really do NOT want to see fluid seeping/leaking from there....Censored

I really don't care where it's leaking from as long as it doesn't interrupt this trip.  I had planned on having the tranny rebuilt, at least, or replaced outright this winter.  I would love to have an overdrive gear so who knows what the final decision on that will be.

Next time the pan is off, put a straight edge on it and look for low spots.

yeah...or maybe I didn't torque it in the right sequence.  You know maybe I went around the pan instead of criss-cross...I'm a dope...a very tired dope.

Well, if you had put a German Cockroach in there instead of a common cockroach, your problems would be over.  A German cockroach would have fixed the leak before he left.

Dave......is it STILL leaking from the pan, as far as you can tell?You dint really specify...just said it still had a leak....
Still, you need to VERIFY where the leak is......almost every place on that trans that can leak will run down, and appear to be leaking from the pan....
Clean/dry it off really well with some brake cleaner....the source will be much easier to find that way. Always look above where the main drip/seepage is to be sure it is not something above leaking down....Thumbs Up

Cleaned her up nice and purty(Joel's words not mine)Big smile and took hr for a quick spin around the block.  No faster than 25 mph and it looks like It's leaking from the pan, passenger side.  The only reason that I'm not sure is how far back the fluid is present on the exhaust.  Starts near the front of the pan and goes a little past the tranny mount.  I used a rubber gasket (which I hate).  I'm going to replace it with a cork gasket and RTV.  Got my kids coming over to help because all this up and down is killing my back.

I don't see any leaking from above the pan but boy, there sure is lots of smoke from burn off around the exhaust and I can still see some leakage from the pan.  I'm taking it in tomorrow to have the pro's look at it.

I'll be there, Dan. We made it to our hotel around 11pm. Saw some of the gang this morning at the fair grounds. Heading to dinner a little later. I have pics on face book.
