thanks for the reply. I shift it into 1st always below 20mph. I usually put it into 2nd though so the car doesn't go so fast down the slope cause i live in a mountainous area. recently putting the car into 2nd doesn't slow it down at all. i can have it in 2nd and roll downhill to 50mph and the RPMs will read ~1200 as if i were just idling. i think slowing the car down by shifting into a lower gear is called engine braking.
