Is this what Richmond uses to seal their 6 speed OD's ?

It looks like bath tub silicone. If anyone has experience, let the rest of us poor cobra slobs and snobs in on the secret...a number of us have experienced said leaks recently on NEW trannys

.. my front edge inside the bellhousing totally gave out and spilled all but the last 1/2 quart into the bellhousing, where it remained until the shop pulled it. By all appearance and function the internals are still OK, but that's mostly because I stopped driving her when something did not "feel right" with the hydraulic clutch, a real manifestation of providence. This stuff is kinda cream/pink. Here's a few pics...

The case is open, vertical and we are viewing the input shaft "zone".
Man that's a mondo amount of sealant... way too much in the opinion of my tranny shop guys

I called Richmond gear today for technical advice/tech line advice on the right hall effect sender unit for my Autometer speedo (the original is dead) and when I told him about the failure of their "bulletproof" trannys, he laughed at me.. until I gave him both barrels, politely. I suspect the only reason was that he figured BiB would go over his head.. I was not a happy camper since I am paying for their factory defect. (Vern took so long to build the car that no warranty would still be in effect.. it's a good thing for vern that a good beating with a stick is illegal, after the C#5p he foisted on this otherwise fine car) I suppose as long as Richmond and Vern continue to sucessfully sell to a gullible public,...

I use Threebond 1104 on my gearboxes. It's a bit of a favourite of mine from my motorcycle engine builds. It's much more adhesive than silicone and doesn't have the tendancy for oil to work its way between the seal and the metal. I use it for sealing crank cases together on bikes and these generally have no gaskets, just the machined faces. on old engines the case halves can warp a bit but this stuff still keeps them sealed.

Here's a link: Threebond

We are looking at several types of heavy equipment case sealant, and black RTV sealant... not sure what we will use yet, but I will pass along the link to my tranny guys.. the seal was lost due to improper materials or case prep or both... Here's a toast with a cold Dos Equis to those down under!

There is a product by the name of "The Right Stuff" made by Permatex. It is available in an aerosol can or in a Small (short) tube for use in a caulking gun. It is more of a sticky rubber than a silicone and definately has more body. I have begun using this in lieu of silicone in most applications, transmission, valve covers, oil pan gasket joints. Orange can.

I have used "Right Stuff" also with great success on intake-to-block rails and breather-to-intake surfaces. Can you tell me, when you use it for valve cover seal, isn't it difficult to remove the covers? It's seems tough to get in there and cut the seal with razor or ex-acto. How do you do it? Thanks,

I only use it on one side of the gasket, I use it to seal the gasket to the valve cover only. I personally do not use any adhesive or sealant between the gasket and the actual cylinder head. From my experience as long as the gasket is not old and dried out it seals pretty well. This assumes the surfaces are flat and straight.

I have passed it along to my transmission shop. We should be getting her back together within the week.. we almost have all the needed items now.
