if yours is like mine, the filter is cleanable, but in my opinion not much of a filter, its basically a screen. So when I did my trans cooler I also put in a disposable in line filter...magnafine.... I for get the part number
just clean everything good. original is silicone tube type gasket for the pan, but I have read that some people prefer the napa pan gasket
and watch your torque on reassembly, I easily stripped one of the pan bolts ( not the drain plug)
