Civic city driving, D3 or D?
Hi Group,
I am an owner of a 05' Civic, which comes with an auto transmission. I have always been driving with D, until I accidently read about the D3 shift yesterday. The owner manual claimed that in stop and go situation, driver should put the shift in D3 so that the trans will not be shifted to the 4th gear. This makes sense to me. However, I still wonder if I should do this in my case. I drive about 8 miles each way to work. There are several cross sections so normally I would be stopped several times. However the city speed limit here is relatively high (40mph). When I put the shift at D3, at a speed of 40mph, I feel the engine does not have much more to give. I wonder if there is a maximum (proper) speed for the third gear. I have never driven a manual car before so I honestly have no idea. Also just for the sake of curiosity, at 40mph, which gear will yield a better gas mileage per gallon, the third gear or the fourth? Thanks a lot! Regards, Doug |

D3 is a great choice for driving in a crowded downtown, but if the distances between stops increase then put it on D. > I wonder if there is a maximum (proper) speed for the third gear.

My best answer is fourth. |

It may even downshift into second. You are hearing the engine rev a little and it is scaring you. The engine could run forever at that speed but it will be quieter and get better mpg if you let it shift into fourth. >I believe what is says is that the stop and go has to be a span of a >really short distance.

As for when to use D3: if you find that the transmission is shifting between third and fourth (due to terrain, fluctuating speeds, barely shifting into fourth before you let up for the next light) then use D3. If it is staying in fourth for at least 20 seconds each time it gets there, then use D4. The only other time to use D3 (or even D2 or D1) is in descending grades. In that case, use whatever gear is necessary to keep brake use at a minimum. |

The maximum proper speed is 39 at half throttle on a flat road, but the maximum speed is 96 or where ever the rev limiter ends. The proper speed is based on engine lugging, or throttle position. The proper speed is programmed by the automaker. If you asked them, they would say the proper speed for 3rd gear is 35-96 based on throttle position. > As for when to use D3: if you find that the transmission is shifting > between third and fourth (due to terrain, fluctuating speeds, barely > shifting into fourth before you let up for the next light) then use > D3.

Descending on D1 could be damaging to the transmission when up-shifting, and the chance of over-reving is high. |
