2004 was the transition year for the ZF suspension with the steerable tag. Coach numbers 671, 681, 685, and 697 on had the steerable tag. Others did not. 695 was the first Newell with the Spyder Controls although it was multiwire rather than single wire multiplex until 2009. 688 was the first Newell equipped with EGR. None of the CAT powered Newells have EGR valves.
During 2005, the styling changed on Newells from the 2000 body style to the 2000i. This is the change to the higher rear cap and the buttresses on the side for the slides. That change occurred beginning with #722.
It is never a good idea to assume that any change took place with the introduction of a new model year. Newell makes continual changes and some folks order a Newell to be built with some features that are no longer in general production. There were still some Detroit Diesels used in early 2006 models until Newells supply ran out. The ZF transmission was not used with the Detroit Diesel. On the other hand, most of the earlier CAT powered Newells had ZF transmissions because at the time Allisons were not rated for the torque of the 625 HP C-15.
