Automatic transmission, Whats faster [D, 1, 2 or 3]?

pontiac equipped hydra-matic 4t65-e 4-speed electronic automatic fwd transverse gear box. each gear has term called gear ratio. gear ratio relationship between number of teeth on 2 gears meshed or 2 sprockets connected common roller chain, or circumferences of 2 pulleys connected drive belt.

when engage in 'd', car computer automatically engage gear according speed of car , how heavy foot on acceleration pedal. once engaged, again automatically switch next appropriate gear base 2 things ive mentioned before (speed , acceleration).

lets in stand still position , intend accelerate fastest way possible. should engage 1st gear , floor accelerator. revs built , off go. shifter placed in '1', car computer rev engine(car accelerating) until have reached redline(maximum engine revolution) of pontiac before manually shift 2nd. , continues until 4th gear , @ 1 point reach top speed of car.

now, above scenario shifter placed @ d stand still. car accelerate automatically changes 2nd, 3rd , 4th without pushing engine limit. acceleration time speed compared scenario above increases.

so, technically speaking while cruising , intend overtake car, can select 2nd or 3rd on shifter increase rate of acceleration of car. leaving in d increase acceleration car computer determines gear suitable acceleration , @ speed are.

conclude, in order accelerate fastest, must select either 1, 2 or 3 depending on current speed of car.ofcourse 1st selected in standstill.

hope helps.
