leak free Toploader?

[CobraV8]

I completely rebuild my transmission some years ago, but soon after that it started to leak from every seam. Now that the engine is out I want to finally get rid of that problem too.

I installed the gaskets dry the first time and only used sealer on the bolts that go into the housing.

I have a new set of gaskets ready, and I want the gearbox to be leak-free this time. I already found the recommandation to put RTV into the openings in the front face of the case where the freeze plug sits and the countershaft end can be seen.

What else is recommended? Installing the gaskets dry again or with sealer? What kind of sealer do you guys use, and where?

1. Use some RTV around the countershaft pin in the front and around the cup plug in the front.

2. On all bearing retainer and tailhousing bolts, use thread sealant.

3. On gaskets, I use an extremely thin coating of RTV on the front and back of each gasket.

4. Make sure your seals are in good condition.

Brent, thanks once again, I'll follow your advice!

Forgot one...

When installing the input shaft retainer, install it dry without a gasket first to see what kind of gap there is between the retainer and the case. It is possible that the bearing is not seated totally and the retainer can't make a good seal against the case.

Alright, I'll check that...
