Re: Job #
Built before 06/07 than it a job 1.
07/07-12/07 Job 2
2008+ Job 3
The Job 1 truck is supposed to have the most engine problems, bad radiator hose, and bad EGR valve.
The Job 2 truck is supposed to have had transmission problems.
The Job 3 truck is supposed to be the best of the 6.4's builds.
*************************************************
There is some minor hardware changes, but mostly it is in the calibration (computer programming) that the computer runs. For instance the job 1 trucks had an external transmission filter along with the regular internal one. Job 2 did not. And as a side note, the job 2 trucks that have had a tranny fail and get replaced under warranty are now equipped with the external filter as well.

Roughly, 2008 Job 1 trucks were produced in the first half of 2007. Job 2 trucks were produced in the second half of 2007. And Job 3 trucks were produced in 2008. So if you find a new Job 1 2008 on a dealer's lot, it has been sitting there for well over a year. And a Job 2 truck has been sitting there for about a year. A Job 3 truck will have been sitting there for only 3 to 9 months.
