Message: [QUOTE="jngreen, post: 1405297, member: 679"] Assuming that your truck has 4.88's, your truck will only run 40-45 mph in second gear before you run out of rpms. I wonder if the truck is actually downshifting into 3rd gear with the torque converter unlocked. Third gear will probably top out at 65mph. This is of course dependent on what tires and gears you are actually running. How much weight are you pulling? In wondering why you don't have the power to pull those hills in overdrive, or why the truck slows down so much. [/QUOTE]
