66 mustang questions
 

Could someone please tell me if it will affect my transmission, drive shaft, ect. if i was to place my car in neutral rev my engine and shift into into drive (I have an automatic straight six)

The short answer is yes. It puts an impact on your transmission, U-joints, drive shaft and rear end. All of these parts have tiny tolerances, i.e. spaces through which they can rotate without contacting the next part down the line. When a load is suddenly applied, it causes these parts to slam into each other, rather than having the load gradually applied. So basically it's like hitting all these parts with a hammer. Your car will probably not grenade if you do it once, but don't make a habit of it unless you're planning on replacing everything soon.

is it different then popping the clutch in A manual. I mean I know popping the clutch wears things out faster but is that saffer then shifting from neutral to drive under load in an auto.


thanks

It's a little different. When you dump the clutch on a manual, the clutch is going to slip a little before it's all the way out. And the load is not applied all at once. It's still pretty hard on the whole drivetrain, just not as bad as a neutral-drop, where nothing is designed to slip.

Accelleration?
 

In addition to ruining the tranny, a neutral drop won't help your accelleration any either.
