You may recall earlier we added a oil to oil diff cooler. This is the Gen 5 ZL1 diff cooler.
These are the cooling lines that move the transmission fluid. It is a loop. There is a electric pump that circulates the trans fluid through a oil to water heat exchanger in the radiator then the chilled trans fluid gets pumped back to the diff. It goes though a oil to oil heat exchanger then back to the trans. This is how GM does it in production except the trans pump is built into the transmission.
The line pass thought the DSE rear crossmember then go through the passenger rocker. Keeps the packaging clean and the line protected.
