I tackled the trans cooler today. If the truck came with a factory aux cooler (like the 2500 and Burgundy's 1500) this install is easy peasy. Without factory cooler, not so much. I'm not sure why a z71 tow package 4.10 didn't have an aux cooler but here we are.
These brackets use the factory hardware, but since this one didn't have the cooler the top holes were just open. I can't remember if they were threaded on the 2500 or just had nut clips on it, but I set a couple 1/4 20 nutserts.
Now to the hoses... The kit comes with a compression fitting and you can just cut the factory hose, spin it 180 degrees, and it all fits. Since my truck only had the trans to radiator and radiator to trans, I went to Oriellys and bought a factory replacement radiator to aux cooler and aux cooler to trans line.
I see why people just use braided hose and make lines when doing this. To get the old radiator to trans line out I ended up cutting it in 3 pieces. Since that isn't an option installing the replacement cooler to trans line, it took lots of cussing and me under guiding and twisting the hose and Burgundy pushing to get it in the right place.
I forgot to take a pic before I snapped the grill back in, but its done. Now she's ready if she gets called in for tow duty.
