You have a drive by wire system, a computer controlled engine and a computer controlled transmission, where the throttle pressure is computer controlled, so there is no adjustment like on an older car. If you need more throttle pressure for firmer shifts then you need to reprogram the transmission computer or diagnose a low throttle pressure problem, which involves a specialized solenoid.
