ATF cooler lines on 06 Silverado

dewfpo · August 18, 2006

I need to know if the 2 ATF cooler lines are exactly the same P/N's for both the '06 Duramax and the '06 8.1L gas engine. (from the Allison to the external tranny cooler)

I would appreciate help from anyone with access to the dealer P/N's.

Thanks,

Walt, I do not have the part #s but I am pretty sure they are not the same. The Allison uses much bigger lines if am not mistaken. I think they are 1/2" compared to 3/8 on the 8.1L

Hi Trey,

Both the Duramax and the 8.1L have the Allison behind them in the 2500HD. I was hoping they used the exact same cooler lines from the trans to the ext. cooler.
