In this video I have a look at a 2009 GMC 2500 that is exhibiting some really strange transmission issues. It only seems to act up once the TCM (mounted on radiator shroud) gets hot. We call it "hot soaking." It sets tons of erroneous codes that just don't make sense. I try to duplicate the symptoms in this video. These are a very common failure on these trucks. -Enjoy!
