ok, i have a lsd transmission from the d15b jdm motor. what type of transmission fluids am i suppose to use? and can i just stick the axles in and spin it freely? the motor and trans are out, and i just installed a new clutch on it. i but the axles in it and try to spin it but can't? is that normal for lsd trans, do i need to put it back into the engine bay with the axles and tires on it before i can spin it? thanks in advance.
