Why do I hear and feel a rumble when I accelerate when turning? I was told by a mechanic that the all wheel drive may be causing the sound. Any suggestions for repair?

First check to see if all of your tires are the same and the tire preasure is the same. any size difference from front to rear can cause it to bind.... if thats not the problem then ..

 

I would take it to a shop that can flush the transmission fluid..( not change it ) but flush it pushing about 16 to 20 quarts through it. That has worked for me a few times on different cars.

 

If that doesnt work then you will probably have to change the solinoid in the rear housing of the tranny

Thanks for your response, Shane. I will pass on the suggestions to the mechanic.
