Hi,
Our 2004 Crossfire ltd has started to develop an annoying transmission whine, the car has 47,000 miles on the clock. The sound fades as you take your foot of the accelerator and returns as you put on the gas... its not particularly noisy yet, but I wondered if this was an issue?
We have taken the car back to the dealer who currently is suggesting a transmission service... not sure that this will be sufficient...?
Our SRT is as quiet as a door mouse so far !!!

 

This issue has been discussed a few times before on this forum - it seems pretty common. Most people seem to think it is coming from the axle or differential rather than the transmission.

 

I have the same problem at around 70 mph. My car, a 2004, only has 16,000 miles on it. Has anyone discovered the cause?

 

Well, it would indeed appear to be the differential. There is a thread on Benzworld about it happening to the slk. Our dealer who we are really pleased with, has agreed with us that it is making the said noise. The question now is, should it be changed now or when it fails?

 

This is the first time that I've heard about this problem. Going by your description of when the whine happens, it sounds to me like it could be the pinion bearing. But that is just my uneducated guess. As for failing, more than likely it will just get louder as time goes on. Good luck with the dealer...Mike

 

I had the same problem two years ago. Do not let them put off swapping out your rear end, do it now, not when it fails...
