Stubborn pan gasket leak I have a 95 camaro z28 auto. I took it on a semi-hard drive and parked it, next morning trans fluids everywhere,I put in a new gasket, as the old one seemed to be leaking on the passenger front, now the new gasket seems to leak the same if not worse. It idled for about 15 min and seemed fine, drove it around the block, parked it, 5 mins later all of a sudden the leak starts again. Its only on the passenger side, I'm not sure what to do, its like the gasket did nothing and I'm not sure where else it could leak from all the way along the passenger side.

Everything was straight when it was off it looked like, I gave in and used some black rtv And a new gasket like a few people told me to do, only tightened hand tight so it can dry good, hopefully this solves my problem.

No worries, you have a LT1 so....
Get the Victor Reinz Tuff-Cork pan gasket, part number W39365TC.
It's a cork gasket bonded to a steel core. It'll never squeeze out. I keep like five hanging in the shop. That and a light coat of Permatex High Tac (NOT SILICONE) and you'll be good to go.

My $0.02 worth...and this is based on 40 years of experience.
When removing the tranny pan, 99.9% of us remove the bolts, and as we do this, tranny fluid dumps out all over the place, because the fluid level is actually above the pan flange. What happens, is some of the fluid backs up into the bolt holes, and unless you blow out those holes with compressed air, this fluid will be forced back out by installing the bolts. This, in turn, will soak the gasket before it's compressed between the pan and tranny body, hence it will leak. Been there....
Another option, if this job is something that you're going to do on a regular basis, go to a marine supply store, and purchase one of the suction tools that's used to change the oil on a boat. You can suck up most of the tranny oil through the dipstick tube, so when you drop the pan, all you'll get is some drippage from the parts that are submerged in fluid, rather than the gushing torrent from a full transmission. This is now how I do this job, and can't believe it took me SO long to think of this.

Well, the new gasket leaks. Its always a minute or two after shutdown. It was making slooshing noises after it was shutdown From underneath which I thought was weird but wasn't leaking, Until a minute or two later guess I'm gonna have to try and get it on a lift or something to make sure it was the gasket leaking.
