Benefits
Factory cooler lines on these trucks rust and weep at the crimped hose sections and fittings, and a leak here drains Allison fluid quickly. Replace if worn or damaged. If you're replacing one line, check the others in the set: the Transmission Cooler Lower Pipe, Duramax | 2003 - 2005 and the Transmission Cooler Upper Pipe, Duramax | 2003-2005. To repair a damaged line instead of replacing it, see the Merchant Automotive Transmission Cooler Line Repair Kit | 2001 - 2005.
Fitment
Fits 2003-2005 Chevrolet Silverado and GMC Sierra 2500HD and 3500 with the LB7 or LLY Duramax and Allison 1000 transmission.
