Don't buy these unless you want to waste a few hours fishing them into the truck to find out the line isn't flared correctly. I've used these same lines multiple times and usually I have to fight with them a little. These don't fit into the radiator or the transmission. Dorman has gone down hill.

No more transmission leak. It was pretty easy to remove and install the transmission lines. The only issue was the retaining clips are a pain to get back in. Due yourself a favor and buy this tool (see photo).The removal of the upper and lower transmission lines was made easier by removing the front grill and lower plastic debris guard. Once you detach the clips slide the lines backwards to allow you the room to guide the lines below the front bumper.

Fairly easy to install and fixed all the leaks I was having with the old lines on my 2004 Silverado 2500HD 6.0L.

I wish I got paid to fix dormans mistakes I could retire by now. The flares were made wrong and too deep to seat correctly No only in the factory fittings bu Dormans replacement fittings too. The line going to the upper radiator fitting was made EXACTLY WRONG, it faces 180 degrees away from the radiator. After some careful bending and twisting I got it to work. If this wasn’t an emergency job I wouldn’t even have tried to install them. The way I see it if you’re gonna go cheap go with the no name before dorman they made in the same Chinese factory right next to each other. They have the gal to put a quality control sticker on it too!

Unfortunately this line was not a direct fit to my 2002 GMC 2500HD like it was supposed to be. The routing was not to factory quality and the end of the line that terminates to the transmission was not compatible with the factory GM coupler on the transmission. Take your time and compare prices with your local GM dealer for transmission lines, the line ended up being cheaper at the dealer and plenty in stock. I have used Dorman lines in the past and have not had this quality issues that I had with this one hope this helps further buyers.
