Large to small is done by cable slackening, and the derailer spring doing the shifting. Is the cable routed correctly around the BB shell? Cables probably have a stainless or plastic guide, check that. I would clean the cable where it goes inside the housing, I use a bit of silicone grease on the cable then put the housing back together. Check the head end of the cables for fraying, scraped coating gumming up the works.
