Shift to reverse click?
I have an 06 3.6 with 64000 miles
When I shift into reverse, from either park or drive, cold or warm engine, I get a click noise that comes from under the good or I should say the front of the car. It's not loud or excessive but is a distinct click. Any idea what that could be? I would say it happens 95% of the time now. I just keep waiting for it to turn into a clunk!

Not sure about a clicking though! Just thought I'd throw in my experience with mine...

Re: Shift to reverse click?
I have the 5spd auto (5L40E) in my 2005 CTS. I get the same noise. I am under the assumption that it happens more when the car is parked on an incline. With all the weight of the car being held back by whatever it is in a transmission that holds everything at a standstill (I believe I have heard it called the parking pin). Granted that does not explain why it happens when shifting from drive to reverse (which I have also experienced).
My shift link was broken when I bought the car, there was a ping/tink associated with moving the gear shifter. And there was noticeable play in the shifter (which is really wierd in an auto). I had it replaced and the transmission still thuds from one gear to the next.
I also have a bad differential bushing, which allows my differential to rock forward and backwards before the torque ever starts turning the wheels... I figure this lurches the car around, thumps the transmission from the back end, pinches my flex disks with ever-changing driveline angles, and I (personally) think it is the number one reason my car makes the noises it does. That is why I am going to have Creative Steel rebuild my driveshaft and replace the transmission mount and differential bushing at the same time. After that, I am going to get my transmission fluid and filter replaced. If that doesnt fix it, then GM designed the cars to make that noise.

I've had the same noise when the car is parked on an incline/decline. One way to keep the pressure off of the drive shaft and transmission is to use the parking brake before putting the car into park. You won't have the hard clunk or pop when shifting out of park.
