With those of you who had a torque converter replaced, did you here or feel any vibrations when in Tow/Haul mode? I'm not sure If I have the issue or not. I get a growling noise and some vibration around 50mph when MDS kicks in. If I put it in tow/haul it's smooth and no vibration. I'm not sure if it's the engine lugging at the low RPM's in full lockup with MDS or if it's a TC issue. I'm about ready to go down and test drive a 2012 to see if there's a difference.

Mine would continue in tow/haul mode. Many said it would get worse, mine was the same either. Sometimes it was harder to get to do it in tow/haul because it would go out of lock-up quicker, but it was definitely there.

In the end before I had mine replaced I could hear it over the radio even when I had it cranked up pretty loud. Nobody with me in the truck missed it. So it was very noticeable. It was especially bad when towing even a light load.

From my experience if it is the TC you will hear it not just feel something.

Just dropped my truck off at dealer yesterday after they ordered a new TC to install. I will post update once I get it back.

Tow/Haul or normal mode should not make a difference. The TCC will go into full lockup in either case. So if you have the converter warble, you should hear it in Tow/Haul as well as normal driving.

[ Note that this assumes your TCC stays in full lockup when you enter Tow/Haul mode. Since the Tow/Haul shift patterns are different, you may have a situation where the TCC will unlock (or go to partial lock) when you enter Tow/Haul. But if you go into full lockup while in Tow/Haul mode, you should get the same noise. ]

MDS is another story. MDS mode disables full lockup; it only allows partial lock. So you should NOT hear the noise in MDS mode. If you hear a noise in MDS, it's not the converter rattle.

Also, note that ERS mode disables MDS (and thus, re-enables full lockup). So if you're trying to diagnose the converter noise, run at light cruise about 45-50 mph. In normal Drive mode, MDS should kick on and you should have NO noise. Then tap the ERS (-) switch to put the trans in "5" (which is normal 4th gear). At this point, the TCC should engage full lockup, so if the noise is present you should hear it.

But as I said before, this is not a durability concern, so if you only hear the noise when you go hunting for it, you don't really need to bother with getting the converter replaced.

The dealer can also look this up with your vin number. The above came from the star case posted earlier in this thread. I had my dealer confirm the number both with the vin and against the star case number. They told me all the incorrect ones should have been recalled, once they supercede then the dealers have 14 days to return them or they don't get paid.

thanks for the info, rep point headed your way.

My new torque converter arrived last week Thursday. I dropped the truck off this morning. They gave me a free rental (Caravan) due to the "early failure" of the torque converter. Picked up my truck this afternoon and found the noise gone.

Impressed with:
How quick they diagnosed the issue.
They didn't argue with me at all.
Quick repair.
Problem appears to be solved the first attempt.
Free rental car.

Dissappointed with:
truck was not washed when I picked it up


This all occured at Burnsville Dodge in Minnesota.

I was aware of the Starz case but I feigned ignorance to gauge how they would react to the noise.
After a test drive, they initiated the Starz case discussion with me and ordered a new torque converter the same day. I was impressed.

I noticed the noise around 3000 miles but it was very subdued and there was no associated vibration.

Since new, my truck is daily driven, has towed 3 cars less than 500 miles total. Build month is June.

Ming got fixed today. The noise is gone. I am a licensed tech so I had to double check the job that was done on my baby. Everything looks good but I checked the transfer case fluid and it was about 1/2 inch below the fill hole. I want to fill it and the fluid was red, its a borgwarner transfer case that has auto mode in my 2011 sport so is the fluid atf 4. How do you know if I have the NVG246 transfer case?

How loud is the noise with a bad Torque converter. I hear something every once in a while but can't determine if it is the TC. The noise that I have is just slightly louder than the exhaust note and a little higher pitch and very intermittent. Thoughts?? Dealer flashed the rig at 3000 mile oil change, no noticeable change in anything after that. Why was that the magic answer???

Mine was bad in to haul mode around 40mph between 1200-2000 rpm light throttle. You had to listen for it but its not there now with the new converter. If the transengineer reads this can you tell me what my 2011 sport with a Borg Warner transfer case takes for fluid. Thanks
