ok seriously, dual logic is just an automatic box, there's nothing special about it that requires any special attention. just drive it without abusing it, and keep the fluid changed in line with the service schedule. the problems you're likely to have are to do with the electrical system controlling the dual logic (especially the semi-auto mode), and nothing you do (or dont do) will have any effect on fiat's electrics, they do what they want when they want, just do what all fiat owners do, keep your fingers crossed it will work and hope for the best.
