Review on ACDelco 20835127 Equipment Automatic Transmission by Jared Tovar

GM Duramax trucks have a history of leaking transmission cooler lines, this is the 3rd part number revision for these lines Trance Cooler I hope GM understands this. The line came all the way to my truck, it fit just like the originals, but fitting replacements is a lot of work. Bumper, grille, skid plate, cross member, fender liner, air filter and intake system must be removed. I used heavy duty zip ties to try to keep them from moving after installation. The part numbers needed for the 2007 Silverado HD Duramax Extended cab were 20835125, 20835127 and 20835123. I like to use original parts for repairs, many people recommend aftermarket kits to fix these radiator lines, look before you buy and decide.
