noise under truck

[tearinitupupholstery]

I have a 99 escalade and a few months ago i had the transmission rebuilt. my mechanic friend and i did the install in my parents driveway since my truck was stuck there. When we did the install we filled the transmission and transfer case with atf. since then my truck has a noise when its under throttle. i can be doing 65 and the second i let off the gas the noise goes away. i just saw that the tranfer case should have been filled with the blue stuff. If i replace the fluid will that fix the noise? this noise is driving me nuts!

no way to tell unless you replace it but you should not decide on whether to to replace it based on whether or not the noise will go away. you have the wrong fluid in there. change it now.

I'm going to change it out tomorrow. This noise doesn't sound good.

i didnt notice it, I had 3 15's in the back so i never really paid attention. but over time it has gotten louder. and now i want to figure out whats going on.

well the noise was my rear end, it blew up lol. i replaced the rear axle and changed from transfer case fluid and front diff fluid and its quiet now. now i need to replace one of my cats and the truck will pass emissions and be good to go!

Keep the volume down a little bit on that tune rocket, too. You just might hear some early warning signs of another problem- like throwing a rod (LOL)
