Thank you both (flood and no_worries) for the excellent "new" info. I'm printing this out and will soon take it in to a new shop. I may have to go to Charlotte, but that's ok. If I had the time and money, I'd take it over to the Freightliner Shop in Chattanooga, TN, as that is the home office for US Express. I guarantee they have done tons of work on these Centruy Classes!
Eventually, I will post the "fix" so someone else with the same problem may benefit.
And Double L, I hear ya! This truck has given me my share of problems!! But when she's right, she's right on!!
