Opinions on RTV vs Gaskets on tranny pan.

Get the good one from Mopar. The 727 gasket is # 2464324AC, the 904 gasket is # 4295875AC. It is nylon over steel with a molded in double silicone sealing bead. You do not put any goop on it. It can also be re-used. Around $25-$35 depending on where you get it.
