3rd Gear Grind

[RiotfunK]

Didn’t want to start new thread. But I’m not getting lock out in 3rd. But.

This has happened to me enough now that it’s really bothering me. I can shift quick/hard into 2nd. Never an issue. If I shift from second to third around 4-5k I get the grrrcchh sound (like if you miss shift) when releasing the clutch. It’s in gear. And will just go from there. This is after warmed up about 10 min. And then I’ll get 4th lock out around same rpm at random. After 20-30 min of driving it won’t do it or just feels way better. I’m thinking it’s the mount of the shifter as it feels like the gates are moved when shifting under load. I’m swapping the clutch line to stainless, going to motul dctf and an mgw in the next few weeks. Ford dealer said was fine. But they just drove it normally plugged into a tech computer. Checked my dash cam after I got it back.
I know how to drive stick. Driven it for years. I’ve raced driving manuals. 3rd gear feels so odd in this thing. I’ve done the steeda spring and perch which helped the initial feel. But again 3rd feels off to me. Car has 8k in it. Bought it with 6k and was a garage queen. I don’t smell clutch. Just annoying third gear even when casually shifting it feels off to me. No grind under 4k just not smooth.

Sounds like a bum synchro. If you are able to reproduce it consistently i'd have a tech ride along with you. Or the service manager.

I get the 3rd gear lockout seemingly randomly, its pretty rare. But i also hear some noise from the tranny when it happens which is interesting. It does seem like it's a clutch problem more than anything.

Dealer says it’s a normal sound. I said same thing to them about the synchro. Seems like a common issue that Ford won’t address from what I’ve read online. Why I asked on here.

I get the slight nibble and have for the 21000/38000 miles that I’ve owned my vehicle.
I think you just keep sending it and wait for stuff to get worse. If it’s internal you’re going to be tearing it up anyways, just wait until it breaks!

sorry. It’s hard to say without driving it and seeing it myself. But I don’t have any weird noises coming out of my 2023 especially not during normal driving. Hope someone else can chime in.
Is it loud enough that video can pick it up? That may help forum users.

So went for a spin. You really need to give it a second after depressing the clutch before even starting to shift. Is there a way to disable the rev hang? I need to have the rpm drop before I can shift and not have an issue. Once you do that, then it is fine.

Go to 3:30 into the video. Same exact gear and sound.

Wow. not normal. Your dealership sucks :(
Maybe Ford is a bear to get to pay out transmission warranty claims and they don't want to deal with the diag and back and forth.

I will chime in to say I seem to have resolved my 3rd gear grind with the Steeda shift bracket. It's easy enough to install without removing anything other than the old bracket.

It's basically a big chunk of metal with less flex than the stock one.

When first installed I had a bit of tougher engagement like the trans was new and need to be worked in again. It was also a bit louder engaging gear. I've had it about a year now and it seems like it's close to stock in sound and operation now and I have not been locked out of any gear since it was installed.

I can get it do make the same noise as above shifting anytime to into 3rd or 4th between 4-5500rpm. Second gear doesn’t do it. Haven’t been able to check 5th since I’d be going way too fast. I can get it to not do it sometimes by just dumping the clutch. Which isn’t the best move when coming out of a turn. Still looking for a reason why and what’s causing this. It shifts perfectly fine below 4k. I haven’t run it above 6k to see. Kind of annoying since it sounds like I’m miss shifting when I’m not since you can hear it outside of the car. Other drivers or my friends hear it when we’re out driving.

All of the little things are helpful, such as the clutch spring, braided line, shifter, bushing insert, motor mounts etc., but a better clutch is really what’s needed to get rid of all of the issues.

One other thought is, you could install an N2MB Wot Box and program the no lift shift feature and experiment with different amounts of ignition cut to see if that helps you get into gear without any issues. The ability to have a 2 step that will allow you to set any launch rpm that you want is also very nice. I have one on my car, along with all of the aforementioned parts and a built tranny and I can either use my factory launch controller up to 5500 rpm and the WOT Box for anything above that.

Doesn't those 18+ bad boys use twin discs ?

Yep, they sure do.

id also like to chime in and say I’ve had this issue since I got the car with 3k miles. I’ve tried stainless steel clutch line, MGW shifter, white line mount, BG synhcroshift, and the master clutch line upgrade as well but the car will almost always grind going into third if I quick shift it. Also flushed with MOTUL RBF 600. Every other gear is fine. Haven’t tried taking it to the dealer but I feel as if a clutch is the only solution now…

I’ve been to two different Ford dealers. One in mass and one in CT and have opened a case with Ford. I’m told it’s how it’s supposed to work due to the twin disc. Ford won’t even look into it more since there’s no code. Even though I can repeat the noise faithfully.

Wtf unless it’s overheating there isn’t any codes.
You can shift casually when cruising under like 3800. But as soon as you go above 3800/4k you have to bang the gears hard and just drop the clutch for it not to make a noise. And even then it’s hit or miss. And it really upsets the ass end of the car at speed. I’m kinda concerned once it’s boosted that it’s going to be sketchy.
I find shifting in the Mustang to be the most inconsistent feeling I’ve ever had with a manual trans, to the point it feels like driving a different car every time I drive it. And is only 3/4th gear. I can shift into 2nd, 5th, 6th at any rpm without issue.
It’s not the synchros or the fork. It’s some sort of rattle in the clutch release itself. And is always on release at 4k+.
It’s been a thing for 10+ years. It’s like the BBQ tick, no actual answers or solutions. I’ve seen the same with the tremec, just no where near the extent of the MT82

I’m going to have the race shop building my motor and stuff look into it and I’ll post back if they have an answer.
