I've been here twice. You need to approach it as a commitment. No amount of hammering helped me on the 3.8 in my sig. I finally deformed a small corner of the pan, worked a screwdriver in, and pried. Once it actually started, it popped right off. The pan had a small section that was warped, maybe 3/8". I put that on a flat surface and hammered it straight. I pried in a manner that the edge, not sealing surface, of the transmission took the force, so no issues there. I had, in my mind, decided that it was ok if the pan had to be replaced. Reinstalled with rtv and no leaks.
Only issue I had, buy the genuine mopar filter. so many aftermarket filters won't properly "cling" to the valve body like they should, falling off as you try to lift the pan. this risks poor sealing, in addition to frustrating assembly.
