Re: New 2012 WK2 Pentastar 3.6 - Downhill Whine
Yes, the noise is pretty high pitched and almost sounds like the wind. Not so much like a gear whine, though. The noise is especially noticeable when going downhill with foot off the gas. Since my first post, I just got back from a road trip for some breaking in. I now have just over 1000 miles on it and it seems like things have freed up a bit. The noise is still there but has become more faint and is shorter in duration. It doesn't seem to last last longer than several seconds after I lift the foot off the gas. But it's still there, also at higher speeds like 55-65. If I accelerate, it dissappers. Maybe it's just normal behaviour and the 4x4 transmission just needs more breaking in? What do you think? Comments anyone?
BTW, this is my 3rd JGC, I have a 96 ZJ and a 2009 WK. Jeep hit a home run with the WK2! My only complaint so far, is that there seem to be some holes when accelerating uphill out of low rpms. Think that could be fixed very well with a six speed. But with all that shifting in a six speed, would the transmission last that long? Not sure.
