These Venting set ups can naturally vary a bit for each Truck and SUV Line Series... but for the Trailblazers and Envoys with 4 Wheel Drive.. the Vent Tubes are highlighted here in RED for the 4L60E... and in BLUE for the 4WD Transfer Case. Off Road Vehicles may require additional modification to allow for venting, taking into account having much of the Lower Chassis-Engine-Transmission deeply submerged under invasive water-mud... from time to time:

And there should be a little cap and foam filter to prevent junk from getting sucked in.
