I hate the stock transmission. I don't drive overly aggressive and when I accelerate away from a stop, the transmission shifts so fast through the gears, I get to sixth before I'm going 40 mph! If I put the car into Sport Mode, when I brake, the transmission downshifts so hard, I get tossed forward in my seat. Is there an aftermarket tuner that can reprogram my transmission to be more aggressive during acceleration but not slam the downshifts when braking? I don't need any more power, I just want a better shifting program.
