Hope someone can give me the answer. After installing a new pan gasket with an aluminum race pan, I can add fluid, not start the car, let it sit overnight and it leaks. It appears to be leaking from the pan gasket, but I have replaced it multiple times and the aluminum pan has a real ridgid pan rail. Other than the pan gasket, what would make it leak just sitting there. If it's the dipstick tube o-ring, it sure doesn't look like it. I looked at the trans with a black light and the fluid does flouresce, but can't really see anything other than maybe coming from between the bellhousing and main case. Would it cause this much leak from the pump seal or o-ring? I don't want to pull the trans if I don't have to. Any help would be greatly appreciated. Thanks
