Can you tell me
Saw previously that you posted you could look up and see from the vin if a duramax had the Allison tranny. Can you look mine up?

also how would I know if it's an lb7 and the dealer says they can't tell if the injectors have been changed is there a way that I can find out?
Thank you

In the pick up trucks, They all had Allison transmissions.
2000 - 2004 were all LB7
2004.5 -2005 were LLY
2006 - 2007 classic were LBZ. The first half of the 2006 was the new design of the LBZ but had the old head gaskets and was designated an LLY but is different from previous 2 years.
2007.5 - 2010 were LMM
2011 - 2016 were LML
2017- current LP5
There is several Deisel specific sites as well as wikipedia.org to get this info from.
