Noise in my 6sp
 

I just bought a 05 with the 6sp. I am trying to figure out all of the noises and only one that really bothers me is in the transmission/clutch area.

When I release the clutch and the RPMs are below 1000 there is a rattle sound from the transmission. I have heard this noise when driving semis and i hit to high of a gear, but that was when there was 80,000 lbs fighting back.

Is this normal?????

stock clutch? my dual disc rattles and the g56 makes a little noise. check the fluid and go from there

The truck seems to be untouched with 37,000 on it so I would guess it is stock.

The transmission fluid was clean but I changed it anyways. still the noise

It does sound like the clutch, it doesn't slip at all but that rattle makes me worried.

pull the trans and see if it really bugs you if its not slipping and fluid is clean and it shifts ok doesnt pop out of gears or grind i think your ok

my 05 does it too, i read a few threads on here that said its normal, hub something yada yada yada

my 96 did this for the 70k miles i put on it.had 80k when i bought it. i know its a 5 speed compared to a 6 but when i replaced the clutch i had the fly wheel machined because there were a couple hot spots. i think what happens is the clutch chatters on these hot spots and what we here are the springs in the disc dampening the vibrations. It went away after i had the knew clutch in with the machined fly wheel. thats just my explaination someone who knows alot more will chime in

Everyone says that there is some noise in the clutch, I will just wait till it goes then prob get a SB.

sounds like a good plan to me! :tu:

I just got an 04 with the 6speed, it does this ecaxt thing your explaining, figured it was the clutch, i will find out when i get a new one after this ones toast

Mine's done it since new. Just the nature of the beast.

Does anyone know if the aftermarket clutches rattle, or is this just common for all clutches

My 05 chatters like crazy at low rpm. My friend has a south bend and it is pretty qiet

I may look into getting a SB

ya i hear they are the best in the biz

your clutch is prob commin apart. i had this prob once. and thats what it was.

Which trans does your '05 have? That was the year when Dodge transitioned from the cast-iron NV-5600 to the aluminum G-56. My NV-5600 has growled since I bought in new... even with the South Bend Con O FE.

In the NV-5600, the noise is just the spring-loaded hub in the clutch disc and totally normal.

Can't speak for the G-56 as I've never driven one, but I can say that they use a dual-mass flywheel and have a different clutch design. I'm guessing they also would have a spring loaded hub and would therefore also growl, but don't hold me to that.

its the flywheel i hate those dual mass pos

The rattle is called "critical power moment"...the guts of the trans and the clutch are vibrating back and forth because its lugging. My 04.5 did it the day I drove it off the lot at zero miles...I got nearly 200k out of the OE clutch.

I currently have a Southbend OFe, and it rattles but I don't care knowing it will hold better.

I had an 05 dually with the cast iron G-56 that did the same thing, I changed the oil to the synthetic 50w that eaton uses in semi transmissions and it took care of 98% of the noise. I put around 100,000 mi on it towing as heavy as 35,000 gross and never had a problem. This oil is a little thick when cold and causes a little stiff shifting until warm,
Good Luck!!
