Build dates 01-07 thru 06-07
First builds of the 08's. Lower valence in front on front bumper much shorter than later job builds.
Radiators would leak, most should be replaced under warranty by now. Also there was a recal for a venturi T to be added to keep the radiators from splitting.
TCM, early on it was thought that the transmission control module was a hold up for transmission life, but has sense been fixed by more refined trans tuning
Transmissions,Job 1 was the only model to have an external filter as well as the internal in the pan. some hard part differences like overdrive planetarys but i dont know all the details so hopefully someone can step in a clarify the changes.
Injectors had a recall for hanging open and filling the crankcase full of fuel, VIN specific recall
Build dates 07-07 thru 12-07
Second build batches of the 08 model year
Got a bigger valence on the front bumper, said to improve mileage by 1-2 mpg
TCM part numbers changed. Other small changes were made hopefully more can chime in with more info
Job 3 pretty much anything built in 08 was a job 3
not familiar with all the changes
