I am curious. What is the difference between driving in D4, D3, 2, 1 and so on? I'm asking because today when i was coming out of campus, I accidently knocked the shifter to D3 (usually drive in D4) and didn't pay attention... When I was on the freeway, the car accelerates unusually faster than normal (with a V2) and the tach is around 4K ~ 5K rpm while not in WOT...

Can someone explain to me how this works? Is it good for the tranny to drive in D3 all the time? What makes D3 acceleration faster than D4?

Curious....

ZZZ

*edit* and the sound is also very different too, it sound nicer and deeper than D4...

 

haha thats your towing gears. d3 is third gear.

haha sorry huy i got to do this

 

ok, but is it ok if i drive with it all the time? I love the mad acceleration....

 

youre driving in 3rd gear instead of in 4th. it accelerates faster cuz your rpms are in a more powerful place. bad for your gas mileage though. that and youre stressin the engine more than you have to the whole time.

 

its perfectly natural to use it. unless you like wasting gas

 

Hey J,

I actually googled it and even looked up in the Mitchell On Demand suite.... couldn't find the answer needed...

 

 

It locks your torque convertor when in d1 or d2.

 

it makes your engine work harder, but isn't it easier on your transmission than d4?
that's the impression ive been under, and im willing to spend a little more on gas to save my tranny.

 

D1, D2, D3 and D4 are simply the 4 different gears on your auto transmission.
D1 with most torque and pulling power, D4 being the weakest.
Your car automatically switches from D1 through 4 in an acceleration, nevertheless, if you are going up a steep hill, towing, you can play with the different gears. Especially going down a very steep slope, to not use your breaks, overheat them and findyourself rolling down without brakes, shift down gears, your transmission will slow down your car and stall it at a speed even if you are going downwards...

 

It's not D1 and D2 :P

1, 2, D3, D4. 1 = gear 1 (I'm not sure for what, really... towing?); 2 = gear 2 (for starting in snow); D3 = shifts from 1 to 2 to 3 but doesn't go to 4th gear; D4 = shifts from 1 to 2 to 3 to 4.

 

1 and 2 are used if you need to tow something heavy. D3 will run through 1st, 2nd and 3rd gear only, will not go into 4th gear which is ur overdrive.

 

good info...very helpful, thanks.

this is why i like AZ better than the rest of the forum... :gheyhug:

 

anybody know the towing capacity on our cars?

 

d4 is overdrive d3 is lower gears and towing
