Replaced the transmission lines on my LB7 Duramax . I was a little bit confused from the instructions so I called the business and spoke with a tech who was able to clarify which fittings to use as the kit comes with different ones to fit many different model years. The installation went very well and cured my leaky lines. The replacement lines are high quality and very robust. I’m not a mechanic but found their difficult rating of 2 wrenches to be spot on. 

8.1 / 496 big block 2002 chevy silverado 2500hd

The lines that I received were exactly what I was looking for, have a 2002 chevy silverado 2500hd with a 8.1 / 496 big block. I did have to make a couple of changes and modify my air intake box to get one of the lines in its natural placement, I did reverse the line coming out of the transmission into the lower part of the radiator, I was missing the 45 degree fitting and that's why I turned it around and put that end into the transmission and then rerouted the line to accommodate the straight on fitting. In all I'm very happy with the lines and it only took about 5 hours to do the work. thx DRP if possible I'll add photos at a later date
