Recently my Equinox started to randomly display " Stabilitrack Off, Traction Control Off, Service Traction Control, Engine Power Reduced". The car than requires the gas to be pressed fully to the floor in order to reach even 15mph. It regularly goes over 4,000rpm to switch gears. This would occur on and off during the day. I went to Autozone to get the "Check Engine" light codes. The following codes appeared: P0121, P0171, and P1779. The P1779 code can be caused by low or dirty transmission fluid according to Autozone. The car has never had its transmission fluid changed. Any advise on what is causing these problems, or if one of these codes is the main root of the problem and is the causing the other codes?
