my gxp trans is acting funny (or so i think.) when slowing down to a stop it feels like when your driving a automatic and you downshift it into 1st/lo gear at too high of a speed and kinda slams 1st gear. it wont do it all the time and it will do it different every time (somtimes its harsher than others.) does this seem like a problem or am i just over reacting? its still under warranty but i just want to know so i dont seem like an idiot
