Its either the power steering pump or the AC compressor. Or both - my compressor wails like a banshee when the AC is on which fortunately is not too often.
I just need to figure out how to finance a Hemi!

|HAFICON||Just odd I don't recall hearing it before but I just had my rear end re-built it was making so much noise it might have drown this noise out...|

|HAFICON||Mine just developed this. I might of got the RPMs way to high while in some sand. I'm way to old to try to sling a few donuts but if looked fun. RPM got a little high engine temp came up some over normal but not much at all. Heard a loud whining noise start and I stopped right then.. every since then the transmission. Whines in 1st and 2nd it also wants to stay in 2nd up till about 5500 RMP. Shifts really smooth. Just rolled over 36012 miles.|

|MikeK46||I don't have a whining noise in my '12 JK Auto, then again I always let the motor warm up before driving.|

I had some whine from my 2003 4.0, but there is definitely more with the 3.6 and 5 speed. I road tested about 6 of them before buying mine and they all had it. I'm thinking that it originates from the engine rather than the transmission. It may have something to do with the roller cams along with internal engine chains, being used on the valve Trane.
It will be interesting to see what the life expectancy of the 3.6 is verses the old reliable 4.0.

|lolpetewtf||Yes it is normal. I hate it. At first I thought something was wrong but it's just the way it is. Annoying as hell.|

|Miser||Hello.......... can anybody answer my question, is this whine on the 3.6 normal?|
|04-07-2013 12:27 PM|
I won't even attempt to answer because: I'm not smart enough and I don't have the automatic.

Where are all of our engine Guru's?
Have you not ever questioned as to why the V6 engines have a whining sound to them and the V8s don't???
I need your knowledgeable opinions as to why PLEASE.............
|04-07-2013 12:14 AM|
Unfortunately it's normal. Mine also sounds tiny and whiney when cold as the rpm increases.
I really miss the deep rumble of some of the old v8 engines.
I may install a mega exhaust system to get some low frequency rumble out of it.
Now to your question as to what causes that high pitch whine, I really don't know. I don't think that there is anybody smart enough on this Forum to give you a answer as to why!

Whining noise when accelerationg 3.6 why?
I have road tested several 2013s and have noticed including mine that when cold and starting off under acceleration there is a whining sound which increases with RPM and then goes away as the auto trans shifts into a higher gears.
I have also read that all v6s have somewhat of a whining sound, does anybody know what causes that noise? It almost sounds like a old sewing machine.
