I wanted to share something that has happened to my ZLE and has caused quite a bit of frustration tracking down the origin of oil vapor smoke from under the hood while driving the car. If you track or street drive your Camaro, it might be worth your time to check the aux cooler in front of the radiator for tiny stones/rocks getting caught between the cooler and the plastic mount holding it in place. Mine has two pin-holes that only come into play when the transmission temps exceed the 190-degree thermostat and begin to flow at higher pressures. This is why it was so hard to find, as driving easy on the highway, my trans temps never reach this temp, thus the oil leaking was intermittent to show up.
