No, perhaps the factory didn't do it that way, but I do. It works. I always use it on paper type gaskets. No leaks anywhere on my car, no globs of dripping permatex either. Just moderately used., so it must be O.K. On many situations, there actually is more than one right answer. Not everything is black or white. I can appreciate the specs from the factory, and how the pros do it, but, what works for me really does work for me. It really is O.K. to do things a little different from the way others do it sometime. It's not an insult, nor is it an argument. It's just another way of doing things.

Never Ever use silicone sealer, rtv, or anything else on a trans pan gasket. Only use sealers called for by the service manual,trans fluid partially dissolves silicone sealer and it ends up in the valvebody. If you can get a reusable gasket do it, they seal much better, torque the bolts, usually 10 footpounds.

This is from the the AERA web site. They rebuild more trannys than anyone on the planet. If you do not believe me with my 48 years of experience maybe this statement from them will convince you. I know its hard for someone to accept they are doing something wrong. But that is why we post. Do as you like its not correct. With that said have a good evening

Personally i would never steer anyone wrong on a subject. My shop has been in business since 1901. My grandfather started it then my dad then me and now my son. The posting i do is to my best ability to be correct. I do this every day and its what i do for a living. I am not a weekend worrier. its great that you guys do your own work. I commend you for that but do not close your mind on facts. We have reps visiting us on a regular bases and we discuss things like this. We do not just do things without research. Hope this helps Have a good evening Vinny

Mr. Renzo:

Appreciate your input and obvious experience. Anyone working in a depot operation gets my attention.
That said, vinnietbird has a good point:

Both your comments and vinnietbirds's are the crux of the issue.

If someone wants to use RTV, the following may be of benefit.
When I talked to Permatex two years ago , Permatex indicated they had a new RTV product that just came out for transmissions. At that time said if I couldn't locate it to use either Gray or Copper (as sensor safe). I wasn't interest then, just went with gasket. I like the reusable rubber ones, but hard to find -- even from dealer. I know on my mom's Dodge, they discontinued the reusable rubber in favor of RTV,
and I've never seen one for the Ford "C" series, at least not in Arizona.

So I guess were at -- like most things -- Caveat Emptor.

I get it. Will move on folks. Been overruled again. No sweat been their before. By the way in my post i specifically posted GRAY. But you never mix gaskets with silicone. Thanks and be seeing you.

Mr. Renzo:

After reading this again, I think part of the confusion in this thread may be the use of the words RTV or Silicone.
When I use these terms, I'm addressing their use to the specific object under discussion. So in this case RTV or silicone would refer to ONLY those formulated and approved for tranny use. I could see where one
might think they could use "ANY" RTV or silicone.

Again, thanks to all for your valuable input.
Please consider this thread closed.

I see Mr. Renzo's points.
It only takes a tiny piece of silicone to cause a major problem inside the trans. (Unlike rearends or engines)
I personally use Permatex # 2 on my trans pan gaskets.

I can see other peoples' views on laying down a bead of silicone and letting it "skin" up before installing the pan. (without a gasket)
I don't believe I would be comfortable doing that, but then again I have never done it before.

We bought our '05 Chrysler van new, and it had black silicone sealing the tranny pan, not a gasket, from the factory. That being said, I have used a gasket on the trans pan when changing the trans fluid, and I've never had a leak yet. I'm just personally not comfortable using silicone on a trans pan.
