the speedo gear is in that thing between the transmission and the drive shaft ( i can't remember what it is called) any ways it has the thick cable with two wires going to it, it could be a number of things in the rear, mine makes a metallic kinda humming sound in the transmission could be the same thing if one of use is hearing where its coming from wrong, and only does it in gear. and we both ave the same truck so we will most likely have the same thing wrong :D yay!!
