[07mugencivic]

My car only has 1,500 miles on it. Fluids can be an issue at 1500miles?

Short Answer: Yep!

Long Answer:You Bet! You never know.

The people on this forum who know what BR-549 means also know what a full service fill up truly means. Since that doesn't exist anymore I'll explain. When you used to get a tankful, a Person would come out of the gas station and start the gas pump. while the gas was pumping he or a group of guys would check your tires, wash your windshields and check your fluids; oil,radiator, and tranny if he could. (Just watch "Back To The Future". The Texaco Men were real.) If there was a problem they would let you know and take care of it for you, you pay for the oil, they put it in for free! See why we miss the "old days".

Now, you are the guy/gal. Two Paths You choose:

Let's say for a minute "hypothetically" your lower radiator hose was not formed correctly and it has a bubble in it. The bubble burst leaking radiator fluid out.

1. You check your fluid at your next fill up: "hey there's no fluid in the reservoir I wonder why?" You check your hoses and notice a wet spot on the lower hose. "Hmm I'd better change that hose." You and your car are one, life is gooooooood .

2. You fill up your car and don't raise the hood. You don't see the empty reservoir. You don't see the leak in the hose. 100 miles later...chunk.....chunk. Listen do you hear it .. The hydraulic wine sound of a tow truck lifting your car into the sky. At 1500 miles, yeah it may be under warranty, but your car will never trust you, never ever again.

Check your fluids EVERY TIME. Your car will LUV you. And luv is a wonderful thing.

EDIT: (Don't get me started about idiot lights, Check lights light up when the sensor says to, if sensor is faulty......)

Now reg. your OP. It could be your ATF level. Or it could be that your shifter wasn't set right at the factory. (Is it difficult to get your keys out?) Drive by wire or not there are still things that could be mis adjusted. Those are the two things that pop into my head.

let us know.

[GChang54]

My car drives perfectly fine its just that noise is obviously not normal. Everything shifts fine its just that when i shift to the Drive gear theres this very quick grind noise when i let the car roll. I've actually read some forums on these issues some people say its a normal thing to have a odd noise on the AT Civics just like people having grinding issues on their MT Civics. But I don't know for a fact if its the same issue. Should I check my tranny fluid?

[GChang54]

BTW inserting and pulling out the key is fine.

YES. Refer to long winded discussion above as to why.

The reason you want to check it at fillups is that, unless you live next to a gas station, you will have to drive the car which warms the tranny fluid, and you will get an accurate reading. You will have about three minutes to kill so you might as well check your fluids. If its low then add some and see if that helps.

Regarding other reply. If the keys come out ok then the adjustment is prob. ok as well. You can also treat it like a standard and shift it all the way down to 1 and see if you hear the noise or there is.........any.........hesitation..

What you didn't say in your OP is are you on a grade(hill) of some kind when it does it. You said it rolls.
Are you pushing in on the brake long enough before you let it roll? More than half a sec.
Does it happen after it warms up or when it's "cold".

If you take it in they might want to know the answers to those questions.

I shifted P to 1 and it was fine no noise. With the inclination it dosent matter its just the first few inches when I roll then I hear the quick noise.It only happens on the D gear. Rolling on R gear there is no noise, just the D gear. I havent checked out my fluids yet cuz I might get unaccurate readings but I should find out how to. I just want to know what the problem most likely to be before I take it in.

It is on your User Manual.

I took my car to my honda dealer and they said that there are no transmission issue.They told me it drove fine did not need an oil change however they could not duplicate the noise that my car made when they roll on D. i duno wat to do about the noise now. I mean it dosent happen 100 percent of the time...

Funny I started replying to this and modern marvels on discovery channel is doing a repeat of lubrication. There talking about Lt. Col. Amautuzio...interesting...

...shudder...

Sorry, the geek in me is bubbling to the surface..must...supress...

There I hit the tivo buton. Now back to the OP. Forgive my description but does it sound like it's hocking a quick lugi? My new car doesn't do it but my old lumina made that noise. It's been a while so I don't really remember what we did to keep it from happening.

I wanna say do some experimenting. Take notes. What exactly are you doing? What grade is the car on? Pointing up, down, fairly level? Is it cold, as in startup not external temp. ? When you put it in park do you immediatly turn off the motor or do you pause for a few seconds? The next time you go out does it do it? Since it doesn't happen all the time, it's prob. something specific to a certain set of circumstances. I'm not saying it's you, I'm saying that to get it diagnosed You may have to do some legwork.

I said it somewhere before I don't remember where. The dealer probobly has a certain way of checking things. So if your car does it in a way that is outside their standard...they are not going to find it.

Above all if you are not comfortable with their answer take it to a tranny shop and get their opin.


......hmm wd-40 marketing was the result of employee theft..interesting...

[GChang54]

Well the dealer just ddrove it around...however the tech obviously had to shift P to D he wouldve heard the noise during roll of the car(probably on a flat surface).But the tech said that he didnt hear anything. But I found out it happens more on a hill when the car's front is facing down.

[GChang54]

Now that I really listen to it..its more of a scrape then a grind. I dont think its a grind then u would be able to feel the grind within the car right??I think its just a scraping noise. I mean is something stuck i doubt it cuz then the noise would be repetitive. its juss P>D(let it roll)*Scrape* then drive is normal.

[sjlarue]

I googled for about an hour and a web sight had these things to look for in a general automatic transmission noise section. Their description of the noises sort of described what you are describing:

"You notice a scraping, grating, or growling noise from the car whenever you start to move forward or in reverse."

1. The transmission fluid level is low.
2. The fluid in your transmission is contaminated.
3. You have an internal problem in the transmission.
4. The idle speed of your engine is too high.
5. You have worn CV- or U-joints.
6. The throttle linkage for the transmission is out of adjustment or damaged.
7. Your torque converter is bad.
8. The transmission's oil filter is clogged.
9. Your flexplate (flywheel) is loose or damaged.

Like I said it is general. I think you can rule out #s 2,3,5,8 and possibly 9 since it's a new car. 1 and 4 are most likely. 3,6,7 and 9 could happen from factory, but doubtful since your not having any other problems.


So i would:
1. Check your RPMs. See if it's revving a little high with the engine warm.
2. Check your fluid after you've let it warm up. Put the e-brake on and run it through the gears then check the fluid.
3. Go to dealer ar auto parts store and see if they can pull up any codes.

[GChang54]

the revs are below 1000 when engine is warmed up and I checked my fluids everything seems to be okay. I dunno could something be stuck? I dont think its the tranny its juss a light scrape noise.

yeah that's the sound mine made. It sound like it's just being a little hesitant shifting into gear. My car was a beater car so I never had it looked at. Wish I had. Then I could advise you more. About all I can suggest to you is get a second o-pine like at an tranny shop, or another dealer.

The thing is that you are going to have to replicate it some way or explain it like you've done here. That's where the notes come in. I forgot to add what the RPM's were when you shift to that previous post.

Do you have some way of recording the sound coming from your car? like your cell phone, or some sort of video camcorder? then you can play it for the tech.

later

[GChang54]

well the rpms dont really matter its just that when im going down a hill it makes that noise..but when im facing up a hill it dosent make the noise.
