Overdrive?

When you are using the manual 1,2,3 and D gears, Will they hurt the motor in anyway if shifted correctly, overtime will it cause damage?

1.You can't shift faster than the computer
2. You can hurt the trans it by downshifting
3.Only reason I ever manually shift is to hold it in gear during autox

The computer won't let you damage the motor by downshifting but as stated there isn't any reason or advantage to shifting the transmission yourself.
If you're traveling down a mountain road, you could use 2 to provide some engine braking so you don't have to ride your brake pedal the whole way down the mountain and burn up your brake pads.

There is an advantage to shifting the trans on your own and its to keep from swapping ends lol. With my 383 and street tires I manually shift it because if I didn't the thing would be in third and backwards before I knew it. Other than that this is a debate that has lasted as long as the trans it's self. For a stock setup yes put it in drive and go. If you tring to launch on street tires, lol do the 1 to 2 on your own and let the computer shift 2 to 3. Just under stand the hanging rpms are not good for the engine unless you built it for that.
