Thanks, ***** ***** from outside the vehicle listened around to see where the noise appears the loudest?

Like under the vehicle or under the hood for example?

Does howling noise describe it best?

Is it effecting the vehicle operation?

(the sound appears to be coming from down underneath the motor/tranny area, when its in park you hear the whinning sound. when it goes in reverese and drive goes away.)Like under the vehicle or under the hood for example?(under the motor area) maybe more towards the passenger side underneath)Does howling noise describe it best?
(yes, its a hawling sound best describes it, it almost reminds me of power steering sound, but its not that)Is it effecting the vehicle operation?it does not appear so, besides the funny burning smell )
Expert:  Chris (aka- Moose) replied 9 months ago.

Thanks for the details. I believe the noise is coming from the transmission or transmission area. Confirm the transmission mount and the surrounding exhaust mounts are good. If so then get it on a rack so you can listen to the trans pan. Within the trans the noise can come from a front pump failure or a concern with the valve body.

Thanks for asking your question and letting me try to help you.

If your confused on why or how to rate me, let me know.

I'm only paid from the deposit you've made when you rate 3,4, or 5 stars.

would low trans fluid cause it
Expert:  Chris (aka- Moose) replied 9 months ago.

If low fluid were to blame then the damage as a result from it has already been done. Low fluid alone can not create this noise.

Customer: replied 9 months ago.
would a code reader read the code or would a bad pump cause a code
Expert:  Chris (aka- Moose) replied 9 months ago.

With no symptoms, no codes would be stored in this event.

i see so i will call u tomorrow want me to smell the fluid in the trans to see what it smell like
Expert:  Chris (aka- Moose) replied 9 months ago.

I see no reason to smell the fluid since I do not believe there is clutch material burnt which is what would cause a odor in the fluid.

Customer: replied 9 months ago.
what would cause the burning smell
Expert:  Chris (aka- Moose) replied 9 months ago.

The age of fluid can cause it to appear to have a burnt odor. If trans oil is burnt it will no longer be ruby red. It will be brownish or blackish and smell kind of like fish.

Customer: replied 9 months ago.
oh im talking about u can smell something burning when it making that noise
Expert:  Chris (aka- Moose) replied 9 months ago.

What does it smell like, oil, wiring or something else?

Can you get under the vehicle to see if you can source the origin of the noise and odor?

Since both the noise and odor occur together can you pay attention to the air suspension compressor.

Customer: replied 9 months ago.
it smell something hot like hot wire i will go under the car in a few to check it out
Expert:  Chris (aka- Moose) replied 9 months ago.

Thanks

ok after listen to it again i hear it very load on the driver side
Expert:  Chris (aka- Moose) replied 9 months ago.

It is not the air suspension compressor then, its on the passenger side behind the front bumper. Can you feel around while its occurring to see if you an feel the source of this noise and odor. The compressor and transmission are the only things that would be effected only occurring in forward gears based on all you have told me.

Customer: replied 9 months ago.
i put it in gear it still there but not as load like in park
Expert:  Chris (aka- Moose) replied 9 months ago.

Have some one help, holding it in drive while you feel around with your hands and ears trying to find the source.

ok so i found out were it coming from it the high hvac inlet heat water hose that were the sound coming from
Expert:  Chris (aka- Moose) replied 9 months ago.

Its coming from the heater core hose connected to the engine and firewall?

If that is the case and its still effected by drive and reverse use then I would check the engine and trouns mounts to see if the engine is flexing over in drive excessive.

However that does not explain the electrical odor.
