Honda CVT

**IceT** · February 23rd, 2006 03:11 PM

Hi,

I'm sorry if there is a similar thread somewhere, but since I can't find it, I started a new one.

Regarding the CVT of Honda, I'm a bit confused about the 7-speed auto mode as compare to driving in just 'D' or 'S'. I understand that having the 7-speed mode in manual will allow you to control the gear setting of the CVT. So, what's with the 7-speed auto mode? Please enlighten me.

7-spd mode is MANUAL MODE. No such thing as 7spd auto mode.

On the contrary, for the Honda Jazz, the CVT works like this.

1. Normal Driving (D) uses the infinite ratios of the CVT with the intent of accelerating while keeping the RPMs down. S and L is the same thing but uses only higher ratios either to increase acceleration or to provide power at low speeds.

2. 7 speed auto mode - Press the 7 speed button only, the CVT will upshift and downshift automatically thru 7 pre-set ratios, just like any ordinary automatic tranny. Fun if you want to accelerate fast.

3. 7 speed manual mode - Press the 7 speed button and press the + - button on the steering wheels allows you to shift freely on the 7 pre-set ratios. It downshifts automatically but does not upshift automatically. You need to press the + to upshift. Very fun to play with.

So, does that mean there's no difference to 'D' or 'S'?

Well, there is. For me, if i'm at D and I want to overtake immediately, I shift it to S. The CVT will go to a lower ratio for that kick you need for overtaking. But if you press the 7 speed mode, its the pre-set ratios that are used already. If you want to downshift to overtake, you step harder on the accelerator and the CVT will downshift or press the - on the steering wheel. Move the lever from D to S or vice versa, the 7 speed mode cancels.

those 7speeds are just small preset speeds for the City/Jazz...i really dont understand how it works coz a CVT is a gearless tranny, ironically that gearless transmission seem to have the highest gear ive ever heard pa (7speeds).

**CVT** · February 23rd, 2006 03:22 PM

I have not come across with '7-speed auto mode'. This could be referring to the 'D' position for AT. ['S' is sports mode.]

I'll check the manual tonight.

now, i truly believe da vinci is a genius! cvts have no gears and is much simpler in concept, it only utilizes a vbelt and 2 cone-shaped shafts which changes in diameter to change power output. yung 7 speeds, just like what Mguy said are only presets to specific "gear" ratios. imagine an fm radio where you can tune into numerous frequencies, you can preset specific stations to corresponding numbers sa stereo right, same idea with the 7 speed mode of the cvt

since the cvt does not use any gears but instead uses varying diameter pulleys, it can have an infinite number of gears so better efficiency

**alwayz_yummy** · February 23rd, 2006 05:16 PM

there is...

on a cvt, d will use infinite number of ratio from its lowest to its highest ratio...kaya kung titignan mo specs ng CVT lagi nakalagay:lowest gear ratio to highest gear ratio..giving you the ratio to maintain low rpm while accelerating..

pag 7-speed auto mode, ung tranny, will shift to 7 preset gear ratio, ala 7-speed regular tranny

kaya nga im pushin my sister to buy a jazz na eh...
baka next month daw...

There IS a 7-speed Auto Mode. In summary, (and as mentioned by Mguy) these are the available settings for the City's/Jazz' CVT

1. "D" or drive mode. -

Pros: Infinite gears available thanks to CVT. No shift shocks, very smooth driving. Most economical because the computer decides which is the best gear for your run.

Cons: "Rubber-band" feeling during metal to floor. It's so smooth that when you push the throttle, it'll smoothly and gently accelerate until you reach the top speed based on how much you pushed the throttle.

>>>>> Now, press the 7 speed mode and you switch to:

2. 7-Speed auto mode

Pros: Now, there will be virtual 7 available gears based on pre defined ratios. 7th is overdrive. Acceleration, is more instantaneous. Try flooring it, and see the computer downshifts as soon as your pedal feels the quick push. There, will be some obvious shifting now as you feel the car lurches forward as it downshifts, and your back being pressed against your seat. Still a very comfortable but more spirited drive.

Cons: Definitely less economical now, as your consumption will depend largely on how you floor the gas now.

>>>> Now press, either the + or - and you enter

3. 7 Speed, "D", Manual mode

Pros: Feeling a la Ferrari driver? Then this is it, you choose your own gear. Response is instantaneous. If you try to redline the car, it will upshift. Rev to your heart's content. The car now behaves like a manual with seven speed. Overtaking is definitely a whole lot easier now.

Cons: Gas consumption now is dependent on how you choose your gears and how you floor your pedal. And, now you feel the shift shock!!!!

>>>>> Now, try pushing back the stick from "D" to "S" for Sports.

4. S mode, CVT, Difference? Check out your RPM, it's about 700 RPM higher than the D mode, right?

Pros: Acceleration is faster than your normal D, or D-Auto. Engine braking is more harsh. Engine is noisier. The car, from the usual tame CVT, has now become louder and peppy.

Cons: Rising prices of gasoline.

>>>> Now press the 7-speed mode again, and you're in, yup

5. S mode, 7 Speed auto.

Refer to 2. Give a little more boost of amphetamines to the engine and that's it.

>>>>> Press the + or -.

6. S mode, 7 speed manual.

Refer to no. 3. Then shout "Amazing!" as you race past that slow poke traveling at 140 kph. I have attained speed of 180 kph with this car at the skyway, and I believe that it can still do a little bit more at this mode.

Cons: With the rising prices of gasoline, it's quite unfortunate that this car won't run on diesel or better yet kerosene...

;)

Hmmm. . . i never noticed the difference between D-7speed mode and S-7speed mode. Have to check it out tonight. Man, gonna have fun tonight!!

**Mguy** · February 24th, 2006 10:20 AM

Ahhh.. . . felt the difference between D-7Speed and S-7Speed. There is more power in the latter. Good for quick starts but is flat as the speed gets higher. Gonna play with it more.

Yes, I agree that it will gel flat, or more like a plateou, BUT,as soon as you reach the 5k-6k RPM, you'll be in for a BIG surprise. For S Manual, it accelerates real fast, flats out, then the second wind!

By the way, I don't know if this behavior is also exhibited by iDSI, since I'm using the VTEC city. Feel the rush.

**CVT** · February 24th, 2006 10:36 AM

Hey guys,- this is really informative. I've been using the car for a year now and have not consciously used the 7-speed auto mode. It's my *wrong* assumption that when you pressed the "7-speed mode", you will be on "manual shift" using the +/- paddle on the steering wheel. Pity pity pity,- because I used my van today. Kung dala ko lang ngayon ito... lalabas ako ngayon at susubukan ko!

I will also try out the 7-speed auto in 'S' mode. I doubt though that I will reach 180kph like dragon21. 1.3 idsi lang ako....

Thanks again!

is it paddle shifter or button?

**dragon21** · February 24th, 2006 11:04 AM

it's a pair of buttons. on both sides to accommodate southpaws.

Paddle shifters were never release here in the Philippines, but in Japan, they were.

yes because paddle shifters came from the late 05 model fit..the facelifted ones..
