Well...from what I can tell, the grinding in higher gear issues have been resolved on the later production dates. As for the difficult engagement into lower gears, might be a little better on later production dates, but is still somewhat there.

This is particularly why I recommended my brother getting the A/T: its been around for a while & is proven, plus there is no maintainance. But, my car is more fun to drive than his IMO, even though his has more power. :jump:

The front TiC bushing replacement made a huge difference on mine shifting down into lower gears & I'm hoping the rear bushings (when available) will have just as much of an impact. Sad to say changing the fluiid to RedLine MTL did not help at all & seems just a little worse since the switch.

Well, I'll update on my Transmission swap on warranty. I'm happy to say 4k miles and no problems out of it what so ever. Even down-shifting on chilly mornings is no problems. I will be installing the front shifter bushings as soon as I get a Short Shifter and will update again.

Im getting some throw out bearing related knocking now or perhaps Im just now paying attention to it.

When I back the car out I let out the clutch to get moving backward but when I push it back in to let it coast down the driveway, I get a "knock knock knock" sound the moment I push in the pedal and I let it in/out about a 1/3 of the pedal travel, but this seems to be the only time I notice it, in reverse. 1st to 2d is also noisy like noisy outside the car kind of noisy and difficult to engage.No driveability issues though, lots of smooth power and reading up on google it certainly seems to not be an unusual occurance, a noisy TOB.

Im admittedly getting tired of noises and issues in this area of the car though, shifting quality, noises, etc..,

The ambient air temps have been up in recent weeks and I don't see that there's any improvement in shift quality, I was kind of hoping with leaving winter behind that my shifting was going to improve. On the upside though its much quicker to warm up and thus easier shifting, sooner than winter months/temps.

My shift quality got much better in warm weather (after lube change from dealer) but it makes that knocking pinging sound when it is not moving - especially with the clutch in and I can feel it in the shifter. Mine has been doing that for about 7,000 miles. Recently I have started getting transmission whine in 1st and 2nd at low revs and also a rather violent vibration in the shifter when I let it engine brake down from high revs when it reaches 2,900-2,800 rpm - it feels like a vibrator on steroids. Basically starting to sound like a broken GM auto trans - like a supercharger whining but like 5% as loud as a real one. It is very subtle, but, it is there and if I push the shifter further into the gate while moving it gets about 2x louder until I release it into the resting position in the shift gate (1st or 2nd).

I too am tired of all the fucking noises .. so far I have:

Creaking seat bolsters - especially at the seat belt
Clicking seat back when you accelerate
Rattle from the dash and top of the door interior plastics by the mirrors when bass hits .. actually its pretty much all of the interior door plastics
Creak from the rear somewhere when I back out of my driveway on cold days
Rattling from the sunglasses holder - empty or with a pair inside
Rattling glass when you shut the doors
Banging from the passenger side belt buckle hitting the interior wall when the windows are open
And of course my transmission ping/rattle

That list is about 50% of why I am selling it.

Wow this is bad, are there any other issues that the genesis coupe has other then the grinding issues?

It looks like you arent very happy with your GC, i have been reading a lot of your post and this is very good info for people who are planning on getting the GC... I hope they fix everything for the 2011 model. Also If you really decide to sell your GC what would be your next car to purchase?

I have the noises above that I listed in bold, but the rattle at dash/windshield is more of a creak. The rattle from shutting the doors is due to the door design with no upper structure for the window to brace against upon shutting. The passengers seat belt buckle is also a design issue where wind turbulance is the culprit. I drove a U-Haul this past weekend moving our stuff into our new home & experienced the same thing from the passengers side seat belt of the truck. You can buckle the seat belt while no one is in the seat to alleviate the noise when your window is down. I too have noticed the ping/rattle when the transmission is under load on take offs or at too low of rpm causing excessive strain.

Well, I'm just getting close to 5k miles now, and the weather is warming up. I really don't have any problems with the tranny at all, and find it;s been very easy to deal with. The only two things I have, and they are minor enough I don't feel the need for a dealer visit is the "feeling" of the car going into second when first driving off after it has sat for a period of time. It seems by the 2nd or 3rd time I hit second, it's gone. It not a loud noise like others have mentioned, you can just sort of feel the gears engaging. The other is you can feel the drivetrain move more than I'd like under hard shifting. This is pretty common nowadays as the car manufacturers like to use softer bushings, but I'm guessing there will be improved tranny mounts at some point.

I've really had no complaints at all so far and I'm loving the car. I look forward to having it a very long time.

 

[Austin_Milbarge]

^ I also have that rough 2d gear engagement for the 1st or 2d time in the morning but it quickly smooths out after that, its a rough feel in the stick accompanied by some audible noises like the linkage at work or something, but it's not a grind of the gears by any means.

 

[Insane]

Yeah...it's almost like the gear is floating or something and thumps into place. Almost like a lack of pre-load.

Wow, i'm just surprised how exaggerated some posts are. As a Tuner and Drifter for almost 6 years now, i can say that when you drive a manual tranny car you will always feel the gear motions more then the automatic. And plus those "grinding noises" most likely are time when your timing is not right with the clutch and forces it into the gears.

but then again this is just my opinion and also is based on experience.

Just remember people, don't treat that clutch like it's made for racing, because its not a racing clutch so by doing hard and quick shifting and off timing with clutch release can cause MAJOR problems. If you want to shift harder and quicker, then upgrade your clutch and at least change to a better tranny fluid, Royal Purple is highly recommended (but it will cost you an arm and a leg).

Also, guys, creaking noises will always be there, because look at the cars specs, it's not a luxury sports car even though it's the "Genesis's" Coupe model, and you can't expect it to not have any creaking on the plastic panels. And if you live in an area that always fluctuates between hot and cold weather then these creaking noises will occur.

and a final note, the two models were made for 2 specific things. If you get the 2.0T then that is made for tuning. because of its I4 Theta II engine, the compression and over all tuning is more suitable for modifications and upgrades (therefore that is why they went with the turbo). Because FIY the same engine is used in other high performance tuner cars as well, i.e. the Mitsubishi Lancer Evolution and Dodge's Prior SRT-4 models, uses the same engine. and yes there is a 2.4 Theta II engine, but they didn't choose this one or others don't choose this one for factory turbo tuning is because the cylinder walls are too thin and it will not hold up on its compression with large amounts of force. in other words, KABOOM! (a little over exaggerated, but you get the idea :rolleye: )

well enough of me, let me know what you think?

 

[Tufast]

rblr, I think you are correct in all you said except for this engine being the same one used in other high performance cars. The Evo & SRT4 use a variation of this motor that has forged internals & a semi-closed deck allowing them to push upwards of 600whp on stock motor, which is not remotely possible on the Hyundai 2.0t

BTW take the time to introduce yourself in the members intro forum.

 

[rblr87]

For sure Tufast i'll take the time to introduce myself.

But i'm sure i've read that the engine that the Evo and SRT-4 uses the same developed engine. But if i come across that article i'll give it a post.

They share architectural design similarities as they were co-developed by Hyundai, Chrysler & Mitzsubitshi, but they vary enough to call them cousins rather than siblings.

Here's a good thread to read up on the details:

[TLantMagnus]

Thanks for that perspective rblr87...I think you nailed it. Maybe some people's expectations are a bit high for what they are getting, though it's hard not to expect more, especially in a car like this.

On a side note, my good friend owns a Mazda Rx-8, and he told me that he never down shifts from 2nd to 1st gear while moving...that it puts too much stress on the transmission. So maybe there is some truth to that after all (I was told the same t hing by the Hyundai service dude at my local dealership).

I've driven a manual transmission all my life except for a brief stint in a 2.0T Premium Automatic. I can honestly say my 1994 Ford Probe, all my civics, and all my Integras had 100x's better manual in them. I can't remember one time on any of my other cars that I couldn't get a gear to engage, had loud rattling noises from the clutch, and could feel random wobbling in the shifter.

I by no means expect perfection at this price point but I do expect a transmission that shifts without making a horrible racket.

I have a feeling Hyundai had to implement that "torque protection" system on the V6 for a reason, that reason being, the Hyundai designed clutch and transmission in the GC suck.

Agreed - think about it ... I bet 90% of cars with manual transmissions that are lower in price (even down to the Accent Blue) have better transmissions with fewer problems. ... So ya ... I do not expect perfection, but, I do expect ours to be on par with cheaper cars.

 

[pyrophilus]

My GC 2.0T started to grind almost consistently from 2nd to 3rd. It does this in no other gear (and it shifts perfectly fine), except going from 2nd to 3rd (not going back from 3rd to 2nd or from 4th to 3rd).

My 2nd gear is no longer giving me problems, infact, I can even put car into 2nd at aroudn 50mph (if I wanted to), and it will go into the gate, w/o giving me problems.

As far as the 2nd to 3rd grind, when it does occur, I can try pushing the clutch all the way down to the floor (to make sure), and then shift back to 2nd (while still pinning clutch pedal to the floor), and when I go back to 3rd, it grinds everytime, which leads me to think that it's not about me miss-shifting...

This really is bothering me (can't imagine what it's doing to the gears, nor so I want to, and worry about it)...

 

[Austin_Milbarge]

My 5 Sep 10 build date 3.8 track is up in the air right now having the tranny dropped for diagnosis, I brought it in complaining about what I think is the throw out bearing being noisy, hard and impossible 1-2 shits when cold or < operating temperature. I could back it out of my garage and down the driveway, push the clutch to the floor and listen to it go bang bang bang clunk. Sitting still in neutral pushing the clutch in/out would get a clunk each way. Sitting in a drive through with a wall on either side the driveline had an audible rattling noise and when I would shut it down, you could hear it clunk clunk...ting as the rotating mass came to stop.

But they couldn't pinpoint it but could hear rattling in the trans and asked to tear it out to explore. I pickup an 09 Sonata loaner in about an hour.

 

[Tufast]

Keep us posted. I haven't heard the bang bang clunk from mine, but definately have heard the rattle of the throwout bearing when clutch is engaged. I asked my boss (parts & svc coordinator) if I could get it covered since I'm still under 12k miles & stated he could not due the fact I have been tracking the vehicle. Oh well, I figured as much & am sure I can swing the cost of the TOB. I will replace it when I swap over to the twin disc later down the road.

 

[Austin_Milbarge]

Verdict is in...DMF was "coming apart"...replacement is inbound and should have my car back late Tues or Wed perhaps.
