Well we all know how the malibu tends shift gear slowly so if you want to shift gears faster you have to them manually. So I am at the freeway on red light. Then when it turns green I start pressing the gas while on (M mode) and shift gears up until I am 70mph on 6th gear so I can be on RPM 2. Then I just shift the car back to automatic (D). Does that damage the transmission or anything on the vehicle?
