I made that rookie mistake of over tightening, in fact wherever I thought a leak was coming from, I made extra sure that it was tight at that spot. The leak is not a lot, so it's not a must do right away repair. I am just confused if I should get the gasket replaced or just wait it out and hope things get better, since the fluid is still fresh. Plus there is no guarantee that the leak will stop. The truck shifts fine, just gotta make sure that the tranny fluid level is normal. Is it possible to overfiill and cause leaks that way? thanks.
