t56 leak test
I had to measure the run-out on my quicktime bellhousing. To do that, I removed the front plate from the T56. I've connected the front plate back to the transmission with permatex gasket maker. Before I install my engine and transmission into my trans am, I would like to leak test the T56 to make sure the gasket works. Can I use rubbing alcohol? It's much easier to clean up than transmission fluid, and it evaporates.

No, it didn't leak before. I did clean the sealing surfaces, and that took forever. Getting the old sealant off wasn't easy. I used a tooth brush, lacquer thinner, and another gunk remover. And I used ultra gray RTV. It was the first time I did this, and I'd hate to get the transmission mounted and then discover that it leaks.

I also had to use a razor blade to remove excess sealant around the outside of the transmission (after the stuff dried). Maybe I used to much permatex, because it mashed outward when I bolted the plate to specs.

Ultra gray is why it was a pain in the *** to clean off. Use black. I don't know who is feeding the suggestion to use grey; on a non-pressurized die-cast assembly unit, it does nothing better.
A steel bristle brush will take most off easy, razor blade is good too.
Torque all 11 bolts evenly, you won't have issues.
A tiny line will squeeze very little out the edges. Not a big deal to have used too much.

Thanks - that puts my mind at ease. Ultra gray was what was used before. I took the transmission to a shop for stage 2 upgrade. And yes, it was a pain the *** to remove.
