Whining Sound through gears/rpms

[dj_remy]

okay, yesterday i noticed a whining sound that increases with speed when rpms increase, and when it changes gears, rpms go down and whining sound starts over. its definnatly coming from the right side of the car, i suspect a tranny issue, checked fluid, seem okay, but i dont really know for sure. any suggestions?

95 gsx, 16G, turbo intake, auto-tranny w/ less than 11,000 miles on it.

thanks in advance.

its not the tranny, pretty sure its the U-joint bearing, newer tranny, old driveshaft. but i've got some humming coming from the passenger side rear end, speeds up with acceleration as well, is my whole rear end and driveshaft needing replaced and how complicated is it?
