THE VEHICLE WILL NOT SHIFT PROPERLY WHEN TOWING A TRAILER. WHILE GOING UP A HILL, THE TRANSMISSION WILL NOT DOWNSHIFT PROPERLY. WHILE GOING DOWNHILL, THE VEHICLE DOWNSHIFTS TO 2ND GEAR WHILE GOING 60 MPH. I HAVE CONTACTED GM SEVERAL TIMES (THEY HAVE IT ON FILE) THAT THERE IS A PROBLEM WITH THE TRANSMISSION. THEY UNDERSTAND BUT SAID THAT THEY CANNOT DO ANYTHING ABOUT IT. THIS HAS BEEN HAPPENING SINCE IT WAS BRAND NEW. OVER AND OVER AGAIN.
