I have a 2018 CTD that performs and runs great. But if I get above 5k ft ASL it acts crazy. Running with cruise on, it will start to pull (towing) and then kind of hang up until the speed drops then downshift and take off. The transmission and exhaust brake act screwy as well. My question is: has anyone else had or heard of this happening and what the cure might be? Just returned from a trip Albuquerque where it was 6-7k ASL and truck surges and acts so crazy then I got back to lower elevation and it runs perfect. ???
