Well changed the oil on the Terrain yesterday at 12,000 miles but noticed the transmission was wet from fluid. It was getting late so I didnt take much effort in finding where it was coming from. So I guess its into the dealer tomorrow. Anyone else see any trans leaks or oil leaks to speak of? I just hope this isnt signs of things to come.

Thanks
Jason

Another common problem with this particular transmission. If you look at the top of the driver's side transmission case, you'll see a black colored cap the size of a half dollar. That is usually where it leaks from the top...leaking to the bottom. These transmissions are supposed to be sealed...the cap allows for some excess to drain...I don't know if GM engineered it that way, but it is very common.

at least this would be an easy fix.

I had my transfer case replaced in my 2011 GMC Terrain about 2 days later it started leaking transmission fluid. The shop that fixed is saying it has nothing to do with what they did but it didnt leak before. After paying 3500 now I have a horrible transmission leak. Do you think this would be related to the work they did or something different?

It sounds related, I would not drive the car at all with it leaking fluid.Could take out the whole transmission. Can you see where it is leaking from?
