When the truck is cold it seems to shift fine, after it starts to warm up it shift erratically. It seems to be worse when you come to a light and set there a little while. When you take off the engine revs for a second and it jerks into gear and goes. The trans fluid seems to be full and I have never added any in the four years I have owned the truck. This all started a couple days ago when I got gas and didn't have this problem before this. I changed the fuel filter and didn't seem to help. I have no DTC Trouble codes set in the truck. I have checked it twice.
