So I'm replacing the accumulator pistons and trying to figure out why my torque convertor won't lock up and when I drop the pan, I find this cone shaped filter. It's maybe 1.5 inches long and maybe 3/8" in diameter. Where's this go and do I need it? Hopefully I'll get a reply before I put everything back together, otherwise, I'm just going to leave it out or I'll put it back in next time I get a chance to drop the pan. If anyone has any ideas, please let me know.. Thanks.
