I JUST PURCHASED A NEW 2005 2500 RAM CTD WITHA 6 SPEED MANUAL TRANS
IT HAS A VIBRATION AND GROWL IN THE SHIFTER AREA. DODGE TELLS ME THIS IS "NORMAL" NOISE BECAUSE THIS IS A NEW TRANS FOR THIS TRUCK. SO BULL ABOUT FLOATING SHIFTER FORKS RUBBING AGAINST THE GEARS. THERE RESPONCE IS THATS THE WAY ITS BUILT JUST GET USE TO IT. ANY TECHS OUT THERE HAVE ANY SOLUTIONS. :help:

When you say "new trans for this truck" does that mean it's equipped with the G56 trans ? It is indeed a HD truck....the new, quieter HPCR engines have a tendency to reveal more drivetrain related noises than the 24V VP44 or 12V trucks.

I don't know if this is a G56 trans all I know is the transmission specialist at the Dodge dealer ship and a reply from dodge company themselfs tell me that this "new" trans makes a growling and vibration noise is normal. If you put pressuse on the stick it will stop. I can believe that dodge,Mercedes would put out a product that is this irritating to drive. The specialist was too quick on answering me. Like I told him you have gone over this problem before. His reponse was thats the noise it makes so that's the way it is. :huh:

Find another truck on their lot equipped with the same engine/trans combo. If the noise is evident in another truck, maybe it is indeed "normal". The G56 transmission has reverse near 1st ("L") gear; the NV5600 has reverse near 5th gear.

For what it's worth. My old 2000 V-10 Ram 4x4 2500 with the manuel 5 speed use to make the same noise. Put over 140k miles on it with no trans problems. But, I understand your concern. new truck, newer transmission. Keep us posted.

The HD manual trannys are noisier than other transmission I've ever had. I think that the quiet diesels now let people hear them more :D
This goes across all 3 brands of HD trucks. There are some heavy gear sets rolling around in there.
You may have the new G56 for the 2500/3500s. You just have to drive another one with the same G56 and see if it is noiser.

Thank You All For Your Input. I Guess I Just Expect A Quietier Ride Form The Trans. After All What We Pay For These Rigs Gear Noise Is Not What I Paid For. I Emailed Dodge Direct With Your Suggestions In The Shop Tommorrow

Same here with a V6 1500

I am experiencing the same problems. I feel like its rattling. Its a noise under the engines rumble. I dont think its right. The truck has 670 miles. Unless its the breaking in period, but noone has answered yet my post. I am taking it in today and also test drive another one there. Honestly, I would have noticed if it had it from the begining. I'll tell you what they tell me today.

There have been problems with the dry dual mass flywheels in the new trucks causing gear rattle, and the associated vibrations that go with it, up through the shift lever. I work for the company that builds the clutch, disc and dual mass for these trucks, I work in product development there, and I have driven MANY of these trucks with the new flywheel, both pre and post production models. They do vibrate and rattle the stick. But also there were some pre-production problems with this tranny, (it's crap compared to the NV5600) and I do believe they were related to this vibration/growl in the stick, and I think some trucks came off the assembly line with a "no shift" condition. I will talk to engineering and see what they know. I will get back to you.

Thank you

Now I feel like I'm getting an answer. It so maddening to go to dealership and get the " you don't know what your talking about " look :crazy: I took in some TSB's I found online , they didn't even have them yet, and was told they don't pretain to my truck thank you again :secret2:

OK, here is what the engineer told me, basically you'll just have to live with it, it's a characteristic of this new trans combined with the new dry dual mass flywheel. The problem is this; the dual mass is obviously MUCH heavier than a standard flywheel. This extra inertia on the back of the crank causes the engines cylinder balance feature to get "confused" because all the extra weight is causing small RPM fluctuations that it does not want to see. When it sees them it tries to balance cylinders, even though it's not an actual balance problem causing this, it's just the added weight of the dual mass. So in it's confusion, the truck shakes and the stick rattles. I personally went with the engineer to Cummins in Indiana for this very problem months ago. Turning the cylinder balance off within the engine management sytem made the vibe go away, but Chrysler is unwilling to shut it off permanently as a fix for production.
So until something further develops, what the dealer is telling you is most likely correct. It's going to vibrate and rattle, and in my experience it will get worse.
Do any of you guys notice any "gear rattle" when the truck is just sitting idling? It'll happen when the trans is hot. Just put the truck in neutral, open your door, push in your clutch and listen to the sound from the trans. Now just let the clutch up, and see if something starts rattling from the trans area.
Maybe cycle the clutch up and down a few times and keep listening.
Also listen for alot of rattling when you shut the truck off too.

Powerful, I know I asked you something on another post. So if you just answer both here. Now will this cause any problems later on? not the noise and rattling, but the transmission itself, is this bad for the gears? Thanks.

It remains to be seen how well these dual masses will hold up. The shaking/vibrating will not get any worse he says, and the tranny itself has proven to be pretty tough, but what you're hearing won't do anything to the reliability of the sytem, according to this engineer. It's just an annoying pain in the ass, that in my opinion a $35,000 plus truck should not have wrong with it.

Powerful, so I went to the dealer yesterday. I drove with a mechanic who also heard the noise and rattle. He said that he did not know what it could be because he never worked on manual trannies another guy does. (GREAT!) :WHT:
So they gave me a loaner and they will check it either today or tomorrow. I also test drove another and I did not hear the noise, but this one had 11 miles. So I cant really tell. It did make the same clunk noise when I pressed the clutch in neutral, accelerated, and let go of the clutch. I told the guy to check the fluid levels and put grease in all the trans parts that needed it. I basically told them all that I have read, but did not tell them that I read it :D . Thanks to all of yous, I sounded pretty pro.
So now its the waiting game. I'll keep yous posted

See why I love this forum so much? It just makes me grin when I walk in and "educate" a 5-star DC service tech on an issue that they havent cared to research.... when you lay out your case and show logical proof, they just look at you like "Damn, I feel stupid now... how the hell does this layman know more about this problem than I do?!!?"

Thanks for the Info Powerful!

Glad to help any of you if I can. But just remember; the dealer doesn't necessarily know anything about the problem, other than that Chrysler tells them it's normal, so don't always blame them. The dual mass flywheel is new to them, and the techs are not up to speed on it yet and have not been trained to diagnose the problems associated with it. But it's going to be a troublesome piece in these trucks, mark my word about that.

If any of you guys have individual questions about the clutch or dual mass flywheel, you can e mail me at [email protected]

And this should spark interest....we're getting the first of the new 6.7L Cummins next week.....

Powerful, why do you say that its going to be troublesome if your engineers say that its good enough? I am confused :huh: . I sent you an email to that address. Let me know please.
Thanks.
