Seems like it's something new every single day with this dang truck. As if the annoying issues I've been having aren't enough this one decided to pop up. Truck had a hydra chip when I bought it, hooking it up to my computer showed the tunes were from May 2014. Decided to update them today to the current tunes on there server. After doing that now once I am driving with the truck in overdrive and I go to slow down and let off the gas the transmission hangs in overdrive until about 30 mph and then downshifts hard into to 3rd, almost like downshifting with a stick, and then decels normally. If I am just in town and never get into overdrive there's no problem. I have absolutely no idea what this could be. Truck drove perfectly fine before this. Has anyone had any similar issues, I can't find anything that seems similar this.
