Clunking noise from the transmission when slowing down!

[Doug Watson]

Same thing with my Dark Horse but it's just the exhaust.

Good afternoon. Would you please send over a private message with your VIN and dealer info so I can look into this clunking noise concern?

Hello Ford..... I sent over my VIN#. Can you please look in to this? Makes me feel like I am driving a POS. I was thinking about selling the car. That is how much it bothers me

Could this be the trans output shaft flange issue ?

Did anybody get q possible TSB or P/N for output shaft flange?

Let me just join the club with the same issue. However I found it out when it happens 7 out of 10 times it also happens when I accelerate after this noise at slow down. Sometimes after a while the noise stops. DH A10 10K km. This is the 3rd issue with the car since May when I bought it. Never raced, never pushed, it's a cruiser. I still have the small spoiler, the dealer is still trying to get me the standard one. First FORD, not the best introduction for sure...

I am exactly in the same situation. Lip spoiler is still on, now the clunking sound… I love the car and i really want to keep it!

Has anyone gotten any info from the "FORD MOTOR COMPANY" member?

I think part number for A10 output shaft flange to be: JL1Z-7089-B. Still have not found a TSB that covers this.

If anybody has P/N or TSB, please post.

If you are going to wait for a official tsb from Ford good luck!

Likely I bought a Ford twice; the first and the last time.
The DH is with me for less than 6 months and I had to take it back 4 times already. I still have the small spoiler and while my dealer is trying to replace it, according to them, Ford still not offering the spoiler in the EU yet. I will take it (again) for this clunking noise, let's see if it get resolved.

For previous Mustang owners; was it like this before?

It's not only Ford it's every brand you can't image when i receive a bmw or Mercedes how long the recall list is. As long it's no major engine or gearbox issues be happy. Small spoiler issue to (Belgium) but i don't care Arp and other brands start providing an even better Quality spoiler then the original at a better price too. Ford makes mistakes just like any other brand right now. Wife is driving a Mazda CX-60 with 10000 miles and it's has already New steering rack driveshaft waterpump etc not what you would expect from Mazda.
If you love Mustang's like i do you deal with it and continue

hello all, fellow 2024 mustang dark horse owner here. i have been dealing with this issue as well for about a month now. Took my car to a dealer 3 times and every single time they sent me back with the car not being fixed. The noise has been consistent and even when showing the techs there at the dealer they specifically told me, “If it gets worse bring it back.” ... Anyways, they claimed it was my lowering springs making the noise. Took them out and put back the stock ones, guess what? Still making the noise. I can say for the time it’s been doing this it has not effected performance at all. So i’m in a pickle of annoyance at the moment.



If anyone has figured this out please let me know, tired of dealing with these dealers.

I've been experiencing the same issue after having an MBPR x-pipe installed on my 24 mustang gt premium. I took it to Riverview Ford and they stated its "normal". I argued with them that I had the same set up on my 18 gt and didn't have this issue. They pretty much dismissed the issue. On another issue the carpet in my 24 gt premium is loose and they stated it was because its "cold outside" and that it would "tighten up" in the summer...

Applying grease to my transmission output shaft splines and the I.D. of the output flange splines resolved my clunking noise. The output flange is connected to the driveshaft. Mine has the stock exhaust. Only takes about 15 minutes to apply the grease if you have a lift. Good Luck

The answer is already given by other members and me with pictures and everything. What do expect more?
