Hi I have an 09 Silverado 5.3 with a 4l60E circle D 2800-3200 converter and all of the normal bolt Ons and the truck is tuned my issue is that the converter will not stay locked when on the freeway? Tuner says he has it sat up to stay locked but for some reason it will not every time you let off the throttle it will down shift and then lockup again if you keep on the throttle, it will stay locked? Is there a setting that's gotten over locked or something different I need to do in the tune? Any help would be greatly appreciated. Here are two different data logs as you can see the torque converter does lock but as soon as I come off the gas and reapply the gas it unlocks then relocks? Iam at a lost any help would be greatly appreciated.
