Fitch downgrades three auto-parts makers - Tenneco (TEN), ArvinMeritor (ARM) and American Axle (AXL), on their exposure to GM (GM). While Friday's aid package is "a positive for the entire supply chain," it's only "a temporary measure that does not materially improve the companies' potential for long-term viability."
