2020 GT 6-spd transmission issues

[billiam8855]

I'm brand new here so my apologies if this is the wrong place or if this question had been addressed. I would appreciate if anyone can direct me to a good thread on this issue if it is well known!

I have a 2020 GT with the 6-speed manual with just over 3k miles on it, and the transmission is really clunky and inconsistent. About 50% of the time, when sitting at a light in neutral, when I put it in gear there is a massive clunking noise/feel that shakes the whole car. Several times, when backing up and with the clutch in the friction zone, I've heard a loud cracking sound from the engine. Shifts at normal speeds feel super clunky and hard going into gear. Those are the main issues that seem to be related to the transmission and couldn't possible be user error

Other issues which may be related or which could just be my lack of familiarity with mustangs/high-power cars (this is my first mustang and first v8 after 10+ years with a more practical car): On the rare occasions I've tried to have a little straight-line fun, seems like it's REALLY hard to shift from 1st to 2nd without major clutch slipping. Maybe I"m trying too hard to be gentle? I have no idea. Also, putting in the clutch to brake at slow speeds, esp 1st and 2nd gear, there is major rattling from the transmission. Is this normal?

I've babied this thing so far--I only use it for a relatively short commute or around town, and I took it REALLY easy for the first 1k miles (very hard to do), so I don't think it's anything to do with the way I've treated the car so far. Even if I wanted to hammer it, I live in a pretty dense metro area so by the time I shift I've pretty much run out of room. Not trying to be one of those guys weaving in and out of traffic going way faster than everyone else.

So my questions are:
- Is this a known issue? I know that there is a class action lawsuit pending right now about this transmission, do my "symptoms" match up with that?
- Is there anything I can ask the dealership to do proactively? Anything I should do myself?

Thank you all so much in advance for sharing your knowledge, advice, and suggestions!

The 1-2 shift issue is definitely a user error.

Never heard of a reverse issue like that, either a factory freak or user error.

The clunky engagement is part of the transmission.

Short commutes and around town driving are the absolute worst thing you can do for an engine/trans.

Your car should definitely be under warranty, correct? As long as you know how to drive a manual, I'd say take it into the dealership and tell them what's going on. It doesn't sound good...

Sounds like your car has some issues. I have a 2020 and it clunks sometimes, but never more than that. These things you describe do not sound right.

... it really sounds like a transmission/motor mount issue here? These cars are not that difficult to drive stick in as you are describing.

The driveline clunk you hear is normal. When the clutch pedal is not pressed and the gear selector in N, the transmission input shaft is connected to the engine and is rotating. When you clutch in, the input shaft is disconnected but still rotating and begins to slow and will eventually stop turning. If you don't wait for the rotation of the input shaft to stop after clutching in and you select 1st gear, you will get the thump. If this bothers you, clutch in, wait a few seconds, then shift into gear.

If you are having problems shifting, make sure you are fully extending the clutch pedal all the way to the floor. There is also REV HANG to contend with. When driving respectfully, you must wait a good 1 second for the RPM's to drop after clutching in prior to your shift otherwise your shift won't be very smooth. On the other hand, the higher your RPM's and the faster you are moving, the faster your shifting technique needs to be. There's a learning curve to get the timing right. If the car is jerking then your technique is off. Practice being smooth at lower speeds and then gradually increase your speed and shifting.

When the car is cold, it's even more picky about how you shift.
Reverse is a very steep gear and you must feather the clutch correctly otherwise you'll feel the driveline slack bucking and making some nasty noises.

There's no class action lawsuit for your model year.

Practice. I don't think anything is wrong with the car.

I don't know man, that sounds pretty rough for what is essentially a brand new car. I'd take it to the dealership to have a look. The shifters aren't *that* bad. A clunking that shakes the whole car and a very loud noise from the engine isn't normal behavior for any car.

If it's as bad as he says, then he should go have it checked out. It would be good to let us know the outcome.

Mine is a early 2019 GT and I can tell u first hand I have all the problem u are dealing with. The car is at the slow mo dealership (week 3) getting shift forks 1-4 and synchro replaced under warranty . And no it’s not user error it the piece of glass MT-82 transmission and garbage ass factory clutch.

IMO, sounds like normal operation of the MT82. The issues with this were around shift forks, but those were addressed. The overall chunkiness of the transmission is not an issue that can be sued against, just the outcome of a cheap Chinese made unit.

Learn to live with it, or be prepared to throw a bunch of money at it (shifter, clutch etc.) to make it marginally better.

What ever
but to op if you are still driving it at 3k miles the same way you did when delivered to you as new you will always have issues.
there is a learning curve on how she likes it. Don’t deny her what she wants and needs. Warm up to her and you’ll be rewarded with the pleasure a mt can supply
