replaced the transmission pan gasket and filter (#4 on the list). Not hard but sure was messy. I was surprised at how many holes were threaded to accept the filter torx screws. it took me longer than I'd like to admit to figure out which were the correct ones. I was glad to be able to do it without having to remove the skid plate.
