One problem related to automatic transmission has been reported for the 2008 Dodge Ram 2500. The most recently reported issues are listed below.
My 2008, 2500 Dodge truck 4x4 diesel has a bad jerking problem when you let off the fuel and then put it on again. The dealers have changed turbo, wire harnesses, all sensors, egr. . . . . . . . . This has been going on since 7000 miles on truck. I have now 47,000. Everyone including the dealer has said all 2008's do this and it is the factory's problem.
