Does your trans pan weep fluid? Mine does and I was noticing on JimKs site that he offers a pan that keeps your trans cooler. I don't need that as I just rec'd from JimK a nice trans cooler that works well. However his description says the pan won't weep. I was thinking maybe its a fairly common problem.

I'm guessing its OEM. I have never seen a after market pan, but Im confident it looks stock.

Michael, I have heard that the Aluminum, finned, extended volume, cast,
transmission pan manufactured by Ragusa had in some rare instances some
inclusions in the casting that led to porosities that resulted in leaks. I
have not personally seen one, and I have a Ragusa pan that I bought from Jim
K. He has both the Rockwell and Ragusa pans in stock and would be the best
person to contact about this, if in fact it is a problem. I don't know for
sure.

Gary Rockwell's pan is cast with a finer material so it tends to avoid
the weaping issue.
Also the cooling capacity is about 20% better and it holds more fluid.
The origional pan should not weap at all if properly sealed.
There is always a leak from the speedo bullet as the O ring is seldom changed.
We swap the "Bullet" with the special O ring. We carrry them in stock.

The Ragusa pan has been off of my transmission several times, same response, no leak, then it starts leaking after a few miles. I check bolts and make sure they are snug. So, I have to occassionally spray Simple Green on the pan and wipe it off. Even with a little leaking I do like what the Ragusa pan does as far as cooling.

Are you all talking about the same thing?
Weeping from the gasket joint to the transmission?
Or, actually weeping through the casting because of an inclusion?
I had plans to install both the final drive cover and the pan -- has anyone painted them inside with Glyptal or similar? How about clear coat wheel paint on the outside?

You did the right thing getting the external cooler. Even with the aluminum radiator, I have, the external cooler helps keep the temps down. I unhooked the external cooler for a year.

If you are using the stock metal pan. I had a problem with mine weeping around the bolts that secure the pan to the case on a few bolts. I replaced all the bolts with bolts that had a metal flange washer as part of the bolt rather then the stock bolts with a star washer.

Many, many years ago, in a chemistry class, we were told that "Water Glass"
was used by car manufacturers to seal transmission cases against weeping. I
don't know that I ever heard it again, nor have I ever tried it. But
looking at this reference makes me think the old prof. may have known what
he was talking about:
http://en.wikipedia.org/wiki/Sodium_silicate#Automotive_repair
<http://en.wikipedia.org/wiki/Sodium_silicate#Automotive_repair>
I did know that sodium silicate (water glass) was the compound required to
be put in Obama's "cash for clunkers" victims.
Google searches reveal many references, mostly from China, to "water glass
method of lost wax investment casting". Never did find an explanation of
what the water glass is used for, but I've come to suspect it's used in the
sand mold into which the final metal is poured. Firing of that mold would
harden the sodium silicate.
Interesting. Someone should try coating their leaky pan with it and
sticking it in the oven to cure. Water glass is reportedly easily made &
cheap.

I may pull the pan off and see if its flat. I also think Ill get with JimK about that speedo bullet and o ring for sure. I hate drips. At this point Im not sure at all where its coming from. Its not serious at all, but can't stand going under the rv and seeing trans fluid droplets on the pan.
I have a mechanic replace the gasket, next time Im just doing it myself.

Ken,
Back in the late 50s, I worked as a machinist for ARO Equipment.
We had a
government contract for several thousand aluminum bodies for
oxygen regulators
for high altitude aircraft. When they were completed and
pressure tested, they
were porous. We thought we were going to do another run with new
castings.
Alas, the casting company decided to soak them in sodium
silicate. You were
flying after that and are still alive, so it must have worked.
Fortunately!!

Maybe I can file a claim for silicosis with these congested old lungs (don't
mention those 25 years I smoked).
