[QUOTE="FordTechOne, post: 1634584, member: 35543"] The dealer can tell if it's been recently re-flashed and can compare the current calibration file names against the original, but if the tune was installed a while back and not re-flashed to stock before selling/trade, it may not be obvious. Some tuners also use the OE calibration file names, which means an engineer would need to be involved to verify the calibration. If it shifts smoothly when in Drive and only shifts hard in Manual mode, that is an indication that it is calibration related, not a mechanical issue with the transmission. The Workshop Manual states the following: [B]Drive Modes[/B] Optimum shift quality is provided in Drive (D) when the Normal Drive Mode is selected. In Manual (M) or when a different Drive Mode is selected, the strategy will provide more aggressive shifts. [/QUOTE]
