Maxima Forums - why my car shift bad on 1, 2, 3 gear

hi there....after a few runs with my friends, i get 0-60mph at 6.8 seconds...but this morning i went to the track again...i notice my car eru rare...is an automatic max 1995

Well i put deep the foot and the car didnt acelerate i mean is increise the speed but like manual if you are under 20 mph and you are on 5 gear and you acelerate...like that(i was on 1s gear at that time), so didnt push me back as used to do, so the car didnt shift to 1 gear or 2nd...if i was on D my car didnt shift to low gears no matter my foot was try to make a hole on pedan in the floor ejejej.i dont know what happen, right now is running again cool...but may was the sensor of the trasmision??? my trasmision is getting bad after some runs??
