904 Transmission pan

The filter extension is not important. But I like it for three reasons. It helps to keep the pump primed during 4wding, and during hard accelleration. If you have a leak, it's an extra quart or so of safety margin. Con: it sucks up trash from the bottom of the pan just like the original. Aluminum pans will seal with a cheap cork gasket. This is important for the beginner pan installer.
