I have an '86 sedan with auto trans that has 303K miles on it and until this most recent filter and fluid change everything underneath has been clean and dry. Until last week. I noticed trans fluid pooling under the car and the pre cat and cat have been wet with trans fluid. All the trans pan bolts are nice and snug and I saw a drop of the fluid coming from an elbow on the drivers rear side of the trans pan that goes up into the engine area most likely to the trans cooler. I was able to twist and get a wrench up in there and it was just a little loose. So I put a piece of clean cardboard under there and ran the car for about ten minutes....Lo and behold, there was the puddle again and the elbow was nice and dry. I then reached up and followed another trans pipe more to the front of the trans pan and felt another elbow, but there is no way to get up in there to try and tighten it. I appears I'll have to remove the catalytic converter up to where the pipe (exhaust) comes off of the manifold to be able to reach it. I there an easier way and if not, will I have to buy new exhaust pipe gaskets or can I reuse the old ones? Or would it be easier to just remove the entire exhaust manifold back behind the cat converter and I guess buying a new exhaust manifold gasket being nothing of the exhaust system that far up front has never been removed?
Sorry for the long post.\

Thanks in advance for you valuable advice everyone has always been a great help.
