Cause of the 6 speed noise..how long to wait before fixing

[JohndeereG]

As posted already on the board, the fix for the 6 speed rattle is newly designed clutch with a better dampening design. What I found out from the engineering department at Chrysler is the cause.



Believe it or not, the cause is the crankshaft harmonics at idle. The crankshaft is moving in and out and putting pressure through the output shaft into the transmission. The noise is being caused by the plates in the transmission. Apply the clutch eliminates the noise... (light comes on in my head). BTW, they are standing behind the statement of this does not cause damage.





Now is the big question, how long do you think (total mileage) Chrysler would honor the bulletin. What is the mileage window because why replace a clutch at 9,000 miles when you can get a worn clutch repaired (under warranty) at say 25,000 miles. I don't think it is taking advantage of DC because they can't use the bad clutch. They are going to reimburse the dealer now or later. We just benefit 15-20,000 miles of clutch.

According to my s***ler, all the fix consists of is a new disc with tighter springs ,not a whole new assembly! Anyways waiting for mine to come in! 12K on mine now,do not believe I can kill a clutch in25 or even 100k miles even with more power!!

I'm not aware of any dealer that will replace a worn clutch, at any mileage, under warranty. If it's defective thats one thing, but a worn clutch? Page 9 in the warranty booklet specifically says that 'Manual transmission clutch parts are never covered under warranty'



Mine was slipping, warranty was denied because of this, but I didn't want the factory clutch again, so I replaced my own. Yes, the original clutch installation was at fault for the problem, but the clutch I have now is quiet and smooth.

I'm at 22,000 miles and it's going in tomorrow. I have had the problem since new, but as we all know there has been no fix until recently

So, I'll let you know if they take care of it.
