Our 2cents worth ....we 've owned Ford , Dodge , and Chevys . By far the Chevy Duramax is the best on the market . The Ford we replaced the transmission at 100k. The Dodge we replaced the transmission not once but 4times ,twice with the dealer warranty and twice with us ,once with AAMCO ,once with the Dodge dealer in Washington state . Our 2001 had 178k on it when we traded it in 2006 . We only did the service required on it . The 2006 has served us well ,wheel bearings only, it has 176k now and we hope to have it for a long time to come
