My truck is haveing the same old problems with its trans. again . The local dodge dealer rebuilt this about one year ago (20000 mi. ) and this seamed to solve its problems . Now when you are driving at 70-75 the trans will shift down to another gear and then back to OD and also when the cruse control is on around the same speed it will shut itself off ??? , I 'm ready to trade this truck off on something else , I just don't think that this truck is very trustworthy . Thanks for any help you guys can give me . Ken S.
