Hi

Can the automatic transmission be modified via software to act and shift more aggressive?

When I drive a slow corner with my AT car in MANUAL mode I go into first gear to make sure, the engine stays in an rpm range where I ve got optimum power. Lets say my speed at the end of the corner is 50 kmh (30 mph). I go on the gas and the car pulls instantly, because the engine is in an rpm range where it can deliver its optimum torque. Until 60 kmh (37 mph) I stay in first gear, than I go into second.

Same situation in AUTOMATIC mode, end of the curve, 50 kmh (30 mph), I put my foot down. Because the software choses second gear in this situation, the car doesnt pull instantily, because the engine is not delivering that much torque down there. It would be better, if the automatic software in this situation would go into first gear and pull to 60 kmh (37 mph) where the redline is and it can go into second.

Can this be modified?
