The seal on the front pump where the torque converter fits in is no longer available from the dealer because they have completly redesigned the front cover so you need to get the front pump that includes the new cover and seal. Supposably the new designed front pump and cover besides being cheaper to make eliminates some air leaks. It used to be standard practice when replacing a torque converter to replace the seal too. I'm not sure if this still the case but I asked my dealer when they replaced my tc under warranty if they were going to replace the seal too

He said yes them I mentioned the original seal was no longer available at least through chrysler and they would need to get the pump and cover.
Additionally there's a valve built into the pump that wears and there are repair kits availble from third parties for that
