Hi there freaks

I owned a GE6 A/T for about 6 months now, already have 3500 km on it. And I have been having this transmission glitch which i find quite strange.

For those A/T owners, I would like everyone to share about how you switch the shifter from N to D.

Me usually switch to N when I hit traffic light or jams when the car needs to stop completely. I also occasionally shift to N when i meet traffic on a downhill road, and let the car to roll on without having to engage the 1st gear for fuel saving reason (coz it is a downhill).

I have driven several A/T model cars before this and I found that I have no problem with me doing what I described above whatsoever.

When I drive my Fit, suddenly this problem occurs. It is when I do having the car to roll in N mode, then for one and many reason i have to shift to D (while the wheel is on the roll). When I do that, I hear a loud scratching (almost like grinding) sound from the engine. To be precise, it sounds like when you run over an empty coke can on the road with ur Fit .

For you to notice, the noise only come when the car is rolling between 5-20 km/h. when the car is rolling faster than that, the sound never comes. The gear just engaged smoothly. And this does not happen all the time (lets say 20-30% of the time I do the move)

So my question is:

Does anyone with A/T suspect this problem too?

Am I wrong to shift from N to D when the car is moving?

Please share your opinion.

Thank you in advance,

Have a great day

 

How about just leave the car in D like it was meant to be?

If your idling while coasting (N) your wasting more gas then if you would just leave it in gear.

You have an automatic, drive it like one.

what type tranny you have? i-shift?

 

Thanks guys.

Yeah that may be the best option to do.

It is just a matter of driving style. I did a lot of manual driving before. Only during the last 5 years my family started to adopt A/T cars in.

The coast-driving thing comes from my previous driving style with M/T i would say.

Thanks anyway for the kind reply

u rock

 

While the car is moving, shifting from D to N on an automatic transmission is fine. In fact in the older vehicles this was designed as a safety feature.

Let's say that your mechanical throttle linkage is stuck open, you want to stop the car, but you don't want to lose power steering or power brakes. Therefore, you shift the transmission from D to N and apply the brakes to slow down and stop. If you'd simply shut off the ignition you'd lose power brakes and power steering.

However, shifting from N to D while the car is moving is not what the transmission is designed to do. Reference: Shifting to neutral won't hurt transmission : SearchChicago Autos : Letters

 

I dunno the answer but I wouldn't trust the MT owners to give you a good one. I normally hear a loud clang when I shift from N to D when I'm NOT moving. I'm pretty sure it's completely normal as it has always happened, unless you have the service manual you probably don't know a whole lot about the way the Fit's AT works. Not all of them are the same.

 

Alright, just looked in the user manual. Says when shifting from N to any gear press the brake. I imagine this means you shouldn't do it while moving. I've only done this a couple times myself, I'll have to not do it in the future.

 

i too have heard this clang or click wen i back out of my garage and then engage in drive. Honda doesnt address it for the transmission, but rather the brakes. However i dont know if this is the same click or clang we experience and what they mention. But here it is anways:


"Why do my brakes make a single “click” noise when I back out of a parking place and once again when I drive forward?
A clearance between the brake caliper brackets and the ends of the brake pads allows for heat expansion and avoids corrosion between the caliper bracket and the brake pads. That clearance can cause the pads to hit the caliper brackets when you first apply the brakes in a new directions of travel. When you back up and apply the brakes and then drive forward and apply the brakes, the single “click” noise you hear is a normal characteristic of the brake system"

I'm not sure what to think cuz ive never heard of this happening before... then again it is HONDA and they wont put a wrong explaination, i hope lol

 

auto trannies on hondas are no good.

 

 

Really? I checked the shift "grid" in my manual. N to D shift = move lever - no mention of applying the brake. Bare with me, there's a point...



But, flippin to the next page I see additional information for Neutral:




So, yes, it says to press the brake pedal when going from N to D....more importanly, though, the manual clears states to use neutral"...if it is necessary to stop briefly with the engine idling."

How long is briefly? 1.for a short duration
Wow, that helps. Clearly, briefly is relative to one's way of life, but we can assume that "briefly with the egine idling" must include non movement at a red light for anything over, say, 5 seconds...?

Anyway, I stick with what the owners manual says....and it says USE NEUTRAL when we stop briefly. This question has plagued me for years, but I usually end up forgetting about it, and mostly keep an AT in D. If i know a light is long, it's my habit to switch to neutral. I can at least drive the Fit with confidence that switching to N at lights is an approved method - ending all worry/debate in my own mind.

note: I'm fairly certain vehicle manufacturers are legally responsible for the instructions they provide in the owners manuals. Google for many examples of where it went bad for the auto maker years ago, but I don't wanna debate owners manuals.

Surely you don't intend to let that engine go screaming past redline and dropping a valve? Or worse. Surely not.
you're safer losing the PS asnd PB but you will still have brakes and steering. It just means more muscle.

 

In neutral you will still have transmission pumping losses to slow the rpm but its not enough to slow you very much. Or very quickly. as for shifting n to D thats exactly what the tranny process does. If you rev it to 4000 rpm and drop into Drive it will probably make it several times but the torque instant input will not make it last very long.
In short shifting to drive from neutral is a lot like dropping the clutch at 4000 rpm." Fun", but guarantees short life.
