In lay's man explanation, the D with the highest number determines how fast ur car pickups/speeds.
Try speeding with each D's a different intervals and see how fast/responsive ur car will go.

Hello guys. Will make this short. Kinda busy at the moment. The D1, D2 and D3 inscriptions on your gear lever mean that you can engage any one of these three (4 forward gears inclusive of D). The function of this is to enable traction at low speeds. In sandy or very muddy areas, engaging any of the D1, D2 or D3 will restrict the gear from exceeding the respective gearing. Take for instance you select D1, no matter how hard you rev your car engine, your vehicle will never exceed gear 1. This ensures low end traction for sandy terrain or when low end power is needed for towing. If on the othe hand, you select D2, the gear will never exceed second gear no matter how hard you rev the engine. Same applies to D3. If however, D is selected, it allows the gear choose between the 5 available forward gears depending on how hard you rev and the road inclination and conditions. The ECU considers many factors simultaneously and decides the best gear in this case to choose in order to deliver best fuel economy under the prevailing circumstances. Hope this helps. Cheers.

you try Bros!

Hi guys,

I was involved in an argument with friends yesterday, over the use of the Driving gears of an automatic gearing car.

Different car products have different automatic gearing system. Mine is a Honda Accord 2006 (Discussion continues) model,and the gear system is pictured below.

It has a 'P-park', 'R-reverse', 'N-neutral' 'D-drive' 'D3', 'D2' and 'D1' gears.

The argument relates to the functions of the 'D', 'D3', 'D2', and 'D1' driving gears respectively, and under what circumstances should each one be used?.

So tech guys in the house, it's time to show off your knowledge.

Merci!!!


I use d2 and D3 to beat a driver moving at same speed with me.

. @Emekan, you are learned and smart... Ur explanation just redefined my driving experience... We really learn everyday. I applied ur explanation on my 2003 highlander and the transmission is seamless from L to D2 to D... You soft my brother... More wisdom to you.

They represent different gear ratios which controls the speed, torque and traction of the vehicle. They give limits to regulate those performances mentioned.

People that will buy new transmissions jyst went up 700 percent. I don't know which mud you are diving through or hill u are descending that you can't just use d or overtake by pressing hard on accelerator to change geRs.

Likely your questions are asked either on the wrong thread or at the appropriate thread (at the wrong time) after it has gone cold.

Most folks are eager to provide an answer even if it's the wrong answer.

U asked about circumstances u can use them.

For D1, when u're stucked in sand or mud and u need to maintain gear 1 power to get ur car out.
For D2, when u're ascending a hilly road and ur engine is loosing power. To gain instant engine power, u need drop to D2( just like in manual trans)
For D3 (if a car does not have it, OD button does the function), when u're trying to overtake in low rev say 2500 rpm and need to rev up to say 5500 rpm to gain more engine power to overtake successfully.
.
OD button means?

OD button means?

OD - Overdrive. It overrides the automatic gear system so as not to shift to higher gear.
Re: What Are The Functions Of The 'd', 'd3', 'd2' And 'd1' Of Automatic Cars by Vbabs(m): 7:49pm On Oct 05, 2020
- If you have never driven manual transmission, pls stick to using D when you drive.

You need proper understanding of manual gear selection with application of rpm needle along with the sound of the engine to drive an automatic car manually.

D1,D2...all the way to D or the + and - option are all choice to drive your automatic transmission manually.

Sir, if your gear system as well as TPS are functioning properly, hard press on your throttle pedal should initiate a kickdown and rev up your engine. You don't have to shift your gear stick.
