My dodge ram is constantly shifting at all speeds. At times it feels like the truck is spuddering when shifting. Can something be wrong with my multi displacement engine? Is there a way to disengage the mde?

the mds does not work when accelerating, is the engine light on, vehicle should be under 3/36 warranty

Thanks for the reply. I've taken it to the dealer and they hooked it up to the computer and did an update but it's still shifting awkwardly. My engine light has not come on. I had to re-install the factory muffler cause the noise from the flowmaster was driving me nuts. I'm not too fond of the multi displacement engine. I don't really see a difference on fuel economy
