do I have LSD?
 

A friend of mine just bought a jdm GSR clip how can you tell if the tranny is LSD or not before we rip the motor out of the bay? If we spin one rotor are both supposed to spin? or.. is there any simple test like that?

Look through the transmission where the passenger cv axle and intermediate shaft are and look for a bar that should run across the open space. If it is there, no LSD.

i would do this...but you can also can spin a tire/rotor by hand, if you spin one tire, the other should spin in the same direction if you have lsd....if it spins opposite direction the no lsd...
