Ok, I have tried just about everything now, still have a leaker. I have a 350 turbo trans, got everything all bolted up and filled with fluid, had a small leak. figured the old gasket was shot so pulled off the old stock steel pan. They are thin and fairly flimsy, so I figured get a nice thick finned aluminum walled one and a nice thick cork gasket to seal it up. A small bead of RTV on top and bottom of cork (maybe thats the problem) got it all buttoned up, followed the pattern, not over tightened or under tightened, it has alan heads, so just hand torqued it. It sits in my garage for a couple weeks, seems to be sealed, I am gone for vacation for a week, come back, nice puddle below. So what now? Any ideas, I hear the 350s all leak, but this is nuts. Try a felpro rubber gasket? I have one,but ist is fairly thin, seems cork would have been better. Or do I have another problem? Its definitely at the seal, nothing from in front or above. Thoughts?
