I have a 1995 Chevy S-10 Blazer, 168000 miles. My transmission blows out transmission fluide on the front right side and only at high speed. I've changed the transmission gasket 3 times. Twice with a cork gasket and once with a plastic one. I made sure I didn't over tighten the bolts so as not to damage the gaskets. Each time it does the same thing, blows out the fluide at high speed. I bought this vehicle 5 yrs ago from a private owner and it didn't start doing this until recently. Any ideas of what may be the problem.

Hi, by any chance are you overfilling with fluid? If you are installing gasket dry I would try some sealer on it next time. Try a good rubber gasket such as Fel-pro or the like. Have you changed the filter lately? A clogged filter could cause a back-up in the pan and possibly be blowing gaskets for you. High speed means high pressure and you say that's when it happens. Make sure you have all the old gasket cleaned off and the surfaces clean and smooth. It's good not to over-tighten but make sure you have them tight enough. Have done this myself and went buggy trying to find out why I leaked! :oops:
