ACDelco 15791692 OEM Automatic Transmission Fluid Cooler Outlet Line - Replacement Part for GM Vehicles | Perfect for Transmission Repair & Maintenance

If you're looking for a cooler line for the C5500 Kodiak this is the one.It goes to the lower Radiator to "to cooler" side of Allison 1000mh transmission. If your cooler lines come from the bottom of the bellhousing "NOT THE SIDE" this is the correct hose.Mine went out at 67k so durability and quality are questionable with these known terrible crimps on the all duramax products from this era. This is a AC delco original part and came fast when i needed it the most thus the high stars.If this hose goes or any other hoses start leaking i'm upgrading to full hydraulic lines. Might just do it anyway for piece of mind.
