Re: New 2012 WK2 Pentastar 3.6 - Downhill Whine

Has there been any more progress in trouble shooting this problem?

I have this exact problem: high pitch wind noise while coasting with foot off the accelerator. As soon as I touch the accelerator the noise goes away. It is worst after giving it some beans then backing off at highway speeds.

I thought it was a turbo pressure noise ( CRD) but now sounds like it is in fact the transfer case or wheel axels.

Anyone fixed there issue?

Cheers

Re: New 2012 WK2 Pentastar 3.6 - Downhill Whine

took mine into the dealer last week to have some of these mystery nioses checked out...they changed the transmission fluid to a different grade than is installed at the factory and now the noises are gone, and shifts seem to be much much smoother. My tech said there was a TSB for this as well.

Re: New 2012 WK2 Pentastar 3.6 - Downhill Whine

I recognized this noise for the first time yesterday (10k miles);
- when I lift my foot from the accelerator; high pitched whining
- any gear
- so for only in AUTO (QT2)
- gear temp was at around 168F

Did the transmission fluid change help? Is there a fix outside?

Do you mind posting the information from the service receipt?

I checked the TSBs at WK2 Jeeps and I don't see one for this fix.

Thanks.
