allison optional??

wheelie-king · 11-11-2012, 07:01 PM

my friend and i are in a debate about whether or not the allison was an option or in 100% of all duramax's in 2003/2004. He thinks they were optional and i was under the impression that they ALL came with allisons. can someone please help clear this issue up?

if it is an auto trans behind a duramax in a chevy/gmc 2500/3500 series truck then yes it is a Allison 1000 5 speed.

if it is a manual trans it is a ZF6. Only two trans available

Allison is the only automatic trans offered behind the Duramax In trucks

UPDATE: no one gives a shit about vans

/jk lulz. yes they didn't have the allison. but like I said the relevance of duramax vans to this forum or the average citizen is very low. no offense Stepchild.

The invoice listed the auto (allison) as a $2k option vs manual.
