I cant really tell where it is coming from.. sounds like the vents.... though....somwhere inside the vehicle.. because i roll my window down and i cant hear it out there!

 

HEY HAS ANYONE CHECKED TO SEE IF THEY GOT THEIR CATALYTIC CONVERTERS CHECKED. I READ THAT THEY MAKE A WHISILING NOISE WHEN THEY ARE CLOGGED?

 

mine is brand new it was plugged and my truck ran like absolute sh*t had to run in 4th gear just to make any progress running down the highway 5th would sputter and die it made a high pitch wistle sound that you could only hear outside the truck so i highly doubt its your problem

 

Alright i have had a lot of work done to my truck and a whole lot done to the transmission. Come to find out that the trans mission has a bypass valve that will bypass the torque converter where most of the trans fluid is stored. This is so works just like the thermastat on your engine. This is what makes the sound you are hearing i did a full rebuild on mine and had a larger pump and and valve housing. Now the sound in mine is twice as loud and almost sounds like gear on gear timing or a small blower. i hope this info has helped you.

 

so its supposed to make this noise?

 

Yes it is completely normal. If hear a clattering noise with the whistle you will know if you hear it. That means you are pretty much screwed and if you do not have a warranty you are about to spend some money. Mine is so load that i can actually hear it over my blower when i sit inside my truck. if i stand outside i cant heat it over the blower. Good luck man and if you need anymore help you can hit me up at my personal email. This is my forth dakota that i have fully rebuilt the engine and tranny from the ground up. It took me a long time to learn what the hell was goin on on the first one, but now its like nothing to work on it. So if you get the chance to do some big work on it i would do so you can learn. Just make sure you do your research so you dont mess something up.

 

so what part do i have to replace.. and do i have to drop the tranny to do it?

 

Hey is the fluid in your rear differential supposed to be foamy? or bubbly?

Thanks

 

i would imagine so... since it is b eing churned up by the ring gear

 

does anyone else have any clue what that whistling noise is? It also sounds like a ringing inyour ear?
