I have to find time to dig into my front end to see if the Serv# is visable without removing anything. Anyone try this yet?

I tried to get in there with a flashlight tonight to see with no luck. I even took my phone light when the video camera on and tried to look up inside the fender well. I still can't locate the TCM, it might not be too hard to just I pull the front bumper, I just have to have time to do it away from neighbors and nosey people.

I was able to pull mine and replace it by removing the wheel well and the plastic pan beneath the car. you'll have to remove the brake cooling duct as well. Was little difficult but definitely easier than removing the entire bumper.
