Issues with emissions switch. Check engine light will not go off. Also 3 and 4th gear are completely gone out. I do not tow or have had anything even remotely heavy in this truck. It's a 2005 GMC Sierra with only 78,480 miles on it. I am not the only one having issues with this 4 speed transmission. It is not heavy duty enough for this size truck. Gm needs to recall all of these transmissions. When it first started slipping I lost all power going down the road at about 55mph. The vehicle that was behind me slammed on his brakes to avoid hitting me. This problem with the transmission is going to kill someone.
2005 GMC Sierra z71. I am the original owner. This vehicle has 18k miles, yes 18 thousand original miles. This truck does not get beat on at all, no off road etc, and it has been well taken care of since new. There is a rust issue with these trucks. On 5-19-2014, on my way to the car wash my brakes started to feel very soft and the truck was not stopping. I changed routes to my mechanics shop, and while en route lost the rear brakes. I thankfully arrived (driving very slowly) to the front of his shop. I got out and saw a puddle of brake fluid leaking out of the rear end brake lines rear lines were completely rusted. He inspected the vehicle, and as if this wasn't enough, informed that the transmission lines were also leaking (rusted). Mechanic added that I should be prepared for the fuel lines to rust through next. This line replacement job will cost me about 2k. Not to mention the issue with the lower rockers and cab corners rusting. That estimated is for another 2k. I purchased this truck to last me, and apparently gm does not build a quality product anymore. There a numerous complaints about this issue, and gm refuses to acknowledge the problem. Very unhappy!.
