Perfect fit.
Line arrived in perfect shape with all genuine GM labels attached. Fit like a glove. Made replacement very easy. NOTE: This line is for auxiliary cooler to top of radiator on 2011 Silverado 1500. It does NOT run to the transmission.

Fits 2010 GMC Sierra SLE 5.3 Flex Fuel W/ Towing Package
Fits 2010 GMC Sierra SLE 5.3 Flex Fuel W/ Towing Package You’ll only lose about 6 ounces of transmission fluid, but it’s a little tricky to get to.. take off the skid plate and trim up top, don’t lose the clips.

OEM replacement part
New OEM part. Not much to say. Confirmed it fits a fully loaded 2010 GMC Yukon Denali. Old part leaked at the crimped joints where the hard line transitions to the soft line. Hoping to get another 10 years out of this new part.

Correct part, but shipped in a plastic bag?
OEM replacement for a 2007 Sierra 1500 6.2L. The old lines are more difficult to get out than the new ones are to get in. I’d recommend cutting the old ones at the rubber part to save time. I lost about 6 oz of fluid so be sure you have some on hand to top it off.

Lines installed and truck is running perfectly
This was a great purchase and other than being difficult to install, everything was perfect and for far less than having to pay at a NAPA auto store of Benson auto.
