what is first noticeable symptom whem the transfer case is bad , i used wrong gear oil for about 1000 miles?

 

whining noises...

 

you should be fine depending on how you drove the 1000 miles; any launching or racing? I drove like a little ***** with wrong oil for 2,000 miles and i'm still fine. I currently have 35K on the odometer with driving the 2K between 15K and 17K.

 

ok somtig is wrong with my car when i'm driving and i push gas pedal to the floor
rpm go to 4000 and 2 scond later rpm drops 1000 and then the car start pulling
boost is about 20psi all the time

 

that would be your clutch, time for a new one!!!

 

seconded. it sounds eggsactly like your clutch is slipping.

 

will you always hear the whining noise, or just when it's in gear?

 

Every gear, even neutral. The whining will get louder as you accelerate, and quiter as you decelerate. But yeah, sounds like its time for a new clutch.

 

ok but i don't smell anything , usually you can smell burning clutch?

 

It depends.. but your clutch is gone

 

sorry for the OT question.... But there is a little whining noise in all my gears, but it goes away in neutral and doesn't get louder when I accelerate. Is this normal, and is there anything I could do to prevent it? thanks.

 

Well im not trying to be a dick or anything, but SEARCH! You will find alot of your answers if you just search. But yes that is normal.

 

yup. It's the clutch.
