luvmydiesel

Hi, new here to the forum.But have a question for you. I have an 03 2500 dodge diesel and it jumps out of 5th gear.But it only does it when you let off of the throttle. Have any of you had this problem with your manual transmissions. It is still under warranty but my hubby wants to have an idea of what is wrong with it before taking it in. So if any of you know what the fix is on this or know of others that have had the same problem any info would be greatly appreciated..
