yes you can get the allison tranny in a 2500/3500 v8...the new diesels seem to have much more power than previous diesels..its up to her though. the diesel will pay itself off with the work you can do with it

 

After asking that question, i looked on Chevys website and apparently for 2011 they no longer offer the Allison with the Gasoline V8. When you choose the Allison option, it automatically picks the Diesel instead...

 

but if she's wanting to go with one a little older they have the allison in them...now they more than likely have the 6L80e behind them

 

ferrariyellow44,

We have not offered the Allison transmission with a gas engine in many years. You can only get the Allison transmission with the Duramax Diesel engine. I would advise your friend to go with a 2500 Silverado with the Duramax engine.

Thank you
Elizabeth, Chevrolet Customer Service

 

Duramax 6.6L with the Allison and 4WD it is!!
