gas leak

Where is your gas leaking from? Perhaps did someone tell you to order fuel injector o-rings? I'd hate to tell you the wrong part and have you waste money. I will say you need to be very careful when it comes to fuel leaks. That can be a major fire hazard if the gas leaks onto the hot exhaust manifold. If your (auto?) transmission is leaking, it could be the transmission oil pan or something else. You may want to have it checked out to be sure.
