How does ram cylinder deactivation work?

During MDS operation the same four cylinders are always shut down. The MDS solenoids direct oil pressure to the lifters for each cylinder and that pressure pushes in locking pins that allow the lifters to ‘collapse’, so they no longer open the valves. The ECU also shuts off fuel and spark to the cylinders.

The transmission may also slip or refuse to shift at all, which is one of the main 2006 Dodge Ram 1500 transmission shifting problems. Sometimes switching out the solenoids can fix the problem for around $50 to $100 plus labor if you have it done by a shop. 3. Cracked Dashboard
