1999 Dodge Durango Overdrive

My Durano jumps in and out of overdrive as I drive down the road.  I have had a mechanic look at it and he claims he changed the filter and fixed the problem.  It stilll does it.  When it does, the truck jerks and my rpms jump.  It's like I accelerate or brake hard but when I am going down the road at a steady speed.  Help!!!
