Buffalosfree- as for a Dodge 1500- the newer ones have the Mercedes designed 5 speed automatic- built in Kokomo, Indiana. My 2005 1500 4.7L quad cab did a fine job towing a 35' 5th wheel this summer- 11,300lbs total tow wt.. That extra tow range gear gives an extra 300-400rpm downshift kick for hills. The 2005 and earlier had the 7/70 warranty -a big plus. The engine blocks were made in my former plant - Indianapolis Foundry. The blocks now are coming from Brazil and have yet to be fully tested for durability by consumers. Could there be a reason they dropped back to a 3/36 warranty in 2006?
