Well, thanks. But is there anything I can do not to void the warranty? Since it only has 600miles on it.

Take a svc tech fir a ride. It should be in 1st gear at idol. Try putting it in first gear manually when you come to a stoo and see if it happens.

 

[Midnight2012]

Mine does in 2nd and stays in second until I accelerate. Then pops down into first. It's weird as hell but both my hometown and actual dealer said it was mostly normal. They said gears would fix that though. Remember also these cars have more hp than torque.

I put it in 1st manually and problem solved. Or just hard launch it for a second

Your dealer is yanking your chain. If you come to a complete stop your car should shift to 1st gear. If a rolling stop perhaps not but like you say then it depends on throttle. When coming to a complete stop if your auto takes off in 2nd it is not normal.
Granted mine has 3:31 but my buddy has 2:73 with no issues.

 

[Midnight2012]

Yeah, I think my problem is that when I gently step on the gas pedal(really gently) , it's fine; a little fierce, it's screwed. I think it might use 2nd to take off sometimes. That just explains the bumping feeling, cuz throttle delay shouldn't bump. But how can I know what dear it's in? Mine is the basic V6 with no information display.

---------- Post added at 11:14 AM ---------- Previous post was at 11:12 AM ----------

Fuse 47 is for throttle delay right? I will try but throttle delay shouldn't have that bumping feeling.

There is a slight bump because of the driveshaft but you will get used to it. Rather than count downshifts count up shifts from a stop. If I'm just cruising mine will be in 6 th by 40mph and I can count all the shifts. Also manually put your car in 1st and see if you feel the bump when you take off.

Also try one more test for spitz n giggles. Put your 13 in S mode and don't use the +\- to shift and see what it does.

My fiance's '12 Focus does that exact same thing where it feels like it's going to stall out. It drives me nuts but the dealer keeps saying everything is normal. It literally sounds like she's driving a manual when she starts moving when it bogs down and then gets moving.

The Focus automatic is the same trans as in my daughters Fiesta. In reality it is a manual trans with a dual automated clutch. Essentially two 3 speeds In one. I know sounds stupid but read your manual and google it. Ours got real hesitant and rough. Found out there is a TSB on it. Took it in and there were some bad seals. Fixed it runs like new again. But still feels like you let a clutch out when taking off. Because it is. Automatically so to speak. Ever notice that at idle on flat ground it doesn't creep forward like with a torque converter?

 

[Midnight2012]

I had an auto focus a few months ago as a rental and could punch the gas quickly to the floor and release it and the car would not even move? F'up! When taking off from a start it almost felt like it was in neutrel before it kicked in gear.I could actually rev it to about 1k slowly before the car would start to move. I hope the auto stangs are not like that! I find Ford autos to be very sluggish and clumsy especially when pushing it, also lots of rev hang imo.

The Mustangs are not like that. Mustang has a torque converted true automatic. The Fiesta/Focus is an automated manual trans. Just as your rpms go up as you disengage your clutch. Of course they don't tell you this when you buy it.

 

[Midnight2012]

Whew! The auto mustang guys deserve better than that! My late 90s auto stang was a slushbox, glad to hear there better now!

Yeah Mike I really like mine and I've been driving manuals for years. My 65 289 Stang was slushy until I put a shift kit in it. The early Ford automatic tranny's didn't hold a candle to Mopar Torqeflights IMHO. Much better now.

 

[Midnight2012]

and how did you fix it? Or you did't ?

Hard to diagnose without hearing it. But try something. Open your hood without the engine running. Push down and up on one fender at a time and see if you have that noise coming from your lower control arm on either side. Eliminate that possibility before we think about the transmission. It may not be noticeable yet on speed bumps.

 

[Midnight2012]

Idk. I've read on here a few times that the v6 has a tiny but of play due to the shaft being two piece. Try that fuse one night when you gotta go to the store or something.

See that black rubber piece holding the two together? There is your problem.

I believe he said the sound is coming from the front of his car. The DS joint is in the center. I may be wrong but just don't see it making the sound he describes. Play yes but nothing annoying. Even a solid DS is going to have play in the U joints where they connect. And they can break too.

 

[Midnight2012]

That's right, it does coming from the front. I will try unplug fuse 47 tommrrow.

Did you test for the lower control arms like I suggested?

And I don't know but I've read that removing the fuse will be shown by the ECU and a dealer might question it. I did it but it did nothing. Placebo effect IMHO. Poor throttle response, transmission adapted to easy driving etc is not going to create that noise. If you want it to shift more aggressively drive it harder. In fact stick it in S and just drive it for a day or two. You will find D mode will then shift better. It is adaptive learning. Teach it.

 

[Midnight2012]

I didn't yet cuz it's raining hard outside, but I will try as soon as the weather gets better, btw, where do u guys get ur car? I got it from Lindsay Ford, Wheaton, MD

Upland Ford
Upland California

 

[Midnight2012]

So I did what you recommend, however, there is no sound. Also how can I upload the pics cuz I took the picture about the lower control arm. It also has the serial No starts with 1207...

As long has you bounced it hard and there is no sound then we can rule that out. No idea how to upload pics. Can you try to describe the problem in different words?

 

[Midnight2012]

okay, so it feels like after I release the brake and step on the gas, the brake still slightly kissing the plate, thus cause a sound like "Da!" before it completely separates from the plate.(That's just how I feel about the sound and bumping, may not be real scenario or problem) After all, it explains for the reason why car speeds up a little after the sound and bump. Every morning when I fire the car and start driving, the first 0.1-0.2 mile never have that sound. It's just annoying. Mustang is the dream car for me before I came to US (I am a international student study at U of Maryland). But now...

Well that sounds like sticking brake calipers. Keep taking it back to the dealer. Have a tech ride with you.
Sometimes you can get an independent shop to diagnose the problem for you and you can take that to the dealer.
My mechanic does that but I'm in Calif. Try White Lightnings suggestion of pulling the #47 fuse. Also turn your key to the on position but don't start the car. Slowly push your gas pedal all the way to the floor then slowly release it. Then start your car.

Do the fuse first. Once you've done these drive your car aggressively for 10 to 20 miles around town. Don't get a ticket.
I personally don't believe this will fix your problem but worth a try.

 

[Midnight2012]

Are you resetting the mileage computer every fill up?

 

[Midnight2012]

Hello everyone:
So I took my Mustang to my dealer today and had a guy ride with me. They finally admitted and noticed that problem. They think that has sth to do with the "hard transmission engagement". I will post the official diagnose report once I get my car back. Thanks everyone for patiently helping me.

Excellent. I've noticed a slight sound/bumping when not coming to a complete stop. I think it's because the Auto doesn't shift to 1st til very low speed. Then when you step on the gas it downshifts . Seems normal but the wife's Flex doesn't do this.
What's the need for a different transmission other than hers is a 5 speed.

Ok, i'm really lazy and I don't like to read...I read the first post, and I have the same exact problem. What was the solution/answer that everyone came to. More info - (My car stays in 2nd gear when slowing down to a stop, then at a stop, and accelerating again, it almost never goes into first) As the first poster described.

You sure? Have you completely stopped and then counted the shifts? Give it more throttle and see what happens.
Drive it harder for awhile for adaptive learning. If a 11/12 drive around with grade assist on for a few days. Always take it off on the freeway. If 13/14 use S mode but don't shift it up n down with the buttons let it shift itself.

 

[Midnight2012]

I don't listen to them, if I put it in sport mode, it displays which gears I am in on the dash. For normal city driving, it almost never shifts to first. I don't know about hwy. But it does make that clicking noise.

Actually, I have a video of it, I took this video for completely unrelated reasons, but now that you mention it, I think I may have captured the noise.

Noise is at 0:15 and 0:50 It's a v6 automatic, was in Drive, and was not shifting at all.

http://www.youtube.com/watch?v=e1XN9w4FFLI

If your car doesn't shift to first when you come to a stop or wot from 15mph or below then something is wrong with the programming. As for the noise take it to the dealer and tell them you're not picking it up til it's fixed. If you watch the video at :50 you hadn't even started moving yet and the noise is there. This sound is not normal.

 

[Midnight2012]

A BAD NEWS!
So today the dealer call me to get my car back. However, unlike what the guy who ride with me yesterday said, the transmission tech says "it is normal when the car is cold". .

Total BS
I wouldn't have left until the Service Tech got in my car and acknowledged the problem, Here's the thing. When they admit a problem make sure it's in the initial report that THEY did hear it etc. I've had them do that and still say Customer says. Then it comes back can't duplicate problem. They do this to avoid Lemon Laws. I just keep taking it back til they get it right.

 

[Midnight2012]

The service got in my car and acknowledged that problem, but he think that's a transmission prob and find a transmission specialist to test drive it on his own. That trans tech didn't really know what's going on. I guess I need to have several guys sitting in the car to find that problem. Also, the heavier the car loads, the more likely the problem occurs.

You need to go back to the same service tech and tell him it's still there and not normal. If this is where you bought the car then talk to the owner. Don't take no for an answer. Keep at it.

 

[Midnight2012]

I am at the dealer now. A guy just ride with me and says that's coming from the rear end. He says Ford thinks that's normal and he is going to show me some kind of official documents.

If its normal why doesn't mine do it or my buddies or a thousand other Mustangs. That noise is loud and annoying. Don't fall for it.

 

[Midnight2012]

Thanks Rebel great info. Did you listen to his video? That noise is horrible. Can't be normal.

 

[Midnight2012]

Did you ask him about it not shifting to 1st when you are at a stop? Mine stays in second. (I believe)

I don't know about yours but if I manually put mine in second there is a big difference than if I put it in drive and it starts out in first. Try it. Sure is baffling what this noise is op is experiencing. On the video it sounds very loud.
