Well, when the thread has 280 posts, I can't really fault someone for not going back and reading them all.

No, this noise will not hurt the trans (or converter). It is an annoyance caused by a little too much clearance (backlash) in the turbine hub spline. This allows the spine connection to rattle when it is under no torque (which happens when the TCC is fully engaged).

Not all converters exhibit the rattle. It depends on how much spline clearance you have (which will vary due to manufacturing tolerances). You do not need to have the converter replaced if (1) you don't have the noise, or (2) it's not enough of an annoyance to justify getting the work done.

Thanks for the input TransEngineer...

I was speaking to my dealer about all the issues and they sounded surprised however the mechanic advised that they have replaced a dozen so far......

So far so good for me with my RAM... Touch wood I hope I don't have any issues...

Thanks again,

Ed

I just bought my truck a month ago and it has 20,000 km's...i am noticing a slight grinding noise/whining at around 60 km/h thats driving me NUTS...It drives me nuts and i always try to keep the speed below or above the 60km/h so i dont have to listen to it....My truck is a 2010 HEMI.....Does this sound like its the TC ? If so i will be taking it in because with such low km's i dont think this truck should be making ANY noises.

The converter noise only occurs when the torque converter clutch (TCC) is fully locked. Best thing would be to have your dealer drive it with a scan tool to monitor TCC engagement. Normally, in top gear with MDS active, the TCC is partially (not fully) locked, so you would NOT get the noise. Tapping the ERS (-) switch (to put you in "5") should cause the TCC to fully lock, so then you would hear the noise (if it's the converter).

So if you can hear the noise with the TCC unlocked, or partially locked, then it's something other than the converter (and replacing the converter won't fix it).

The dealership had my truck over the weekend and fixed the problem with the torque converter. they couldnt hear the noise i had or anything of that sort but they fixed it anyways and found out that the truck ran smoother than it did before. so as of now my truck is fixed and in good running order at 42,517 miles

Hey TransEngineer thanks so much for your input, i just want to make sure i have ALL my facts straight prior to dropping it off at the dealership tomorrow night. I read ALL 29 pages of this thread, and then went to drive the truck and try and duplicate the sound. I brought the truck up to speed slowly till i hit around 30 MPH when i heard that damn grinding sound, i then hit the tow/haul button and continued to lightly accelarate, this made the grinding(frisbee on concrete lol) noise much more prominent. I just want to confirm that this sounds like the Torque Converter. Just want to say thanks again, i dont know what i would do without all these knowledgable people on this forum!

Michael

Well, "frisbee on concrete" is a pretty good description of the converter "warble", but the speed you report (30 mph) is lower than usual (normally it's around 50 mph), and as I said you should not get the noise unless the TCC is fully locked. I'm not sure offhand how Tow/Haul mode would affect the TCC schedule. But I would demo it for a dealer tech (with scan tool) and see if the noise coincides with full TCC lockup. If not, then I suspect it's something else.

@ TransEngineer....I dont know why i put 30MPH, i meant to say 40MPH and up, whooops lol...I had the truck at my local Dodge dealership today...After waiting ALL day to hear from them and having heard nothing, i decided to give them a call...The only person i was able to speak with was the woman working the service desk, she couldnt tell me much but what she was able to tell me was that i was getting an entirely new transmission installed tomorrow under warranty...I dont know whether this is good news or bad news, she was unable to tell me whether it had anything to do with the torque converter or not, i guess i will find out when i pick it up...
