I tried to do a search on this because I think it's a problem I've seen before, but I could not find what I was looking for. My '04 S430 (7-speed) has started making a noticeable "clunk" when it downshifts at low speeds (coming into the driveway, slowing for a speed bump). I think it's the 3-2 downshift, but it may be 2-1. It feels like there is lash in the driveshaft, but that may be the normal play. Any experience with this? I noticed it the first time yesterday; nothing has changed that I know. No other shifting problems, it clicks off upshifts and forced and normal downshifts just like always. The car has 57k miles. thanks for your help fellas.
