My 2002 F-150 makes a humming noise while I'm accelerating. It starts at about 25 mph, and when I hit about 50 mph it stops. What is causing this noise, and how do I fix it? Also, I was wondering if it is possible to put the V6 out of a Roush Racing Mustang in my truck without a whole lot of fabrication work.

 

Lets work one problem, a humming noise in the drive train. whats the mileage on the tranny, same as the truck, and what is it?
