Thanks in advance for any help anyone can offer. My original c4 was rebuilt about 2-3 years ago, and has since seen about 1000 miles total. This past summer it had a problem about leaking a LOT of fluid out of it when parked. As soon as i brought it back in the garage from driving it, no leaks. In the morning there would be a gigantic puddle of ATF on the ground. So I replaced the pan gasket and at the same time the filter, and also had a drain plug welded onto the pan. Same problem happens. I go under the car today to tighten up the pan bolts and see if I could determine where it was leaking from, looks clean almost everywhere. the only evidence of leaking ATF was on the pan bolts. Is it still leaking from the pan? Is there a different gasket I should use or put some RTV around the bolt holes? Looks like its leaking from the back of the trans. Pics are of the pass and drivers rear corners.
