lol did you really not use periods. I ran out of breath while reading your original post lol.

just practice and you will get there. the car will tell you it needs a lower gear. i.e. you are going 50mph in 6th gear and you hit the brakes to slow down to 30mph. If,you leave it in 6th, the car will slighty shake, wont go anywhere really. thats when you know the car needs a lower gear to push itself forward. good luck and congrats.
