No idea, Jose. If the vacuum line is hooked up and the selector is moving we're running out of options.
Are any of the other trannies maybe missing the small input shaft? There are two concentric splined shafts coming out of the bellhousing when the torque converter is out. A large one which doesn't move, and a small one which does. Is the small one there? If not, then the torque converter isn't passing any power to the oil pump and tranny innards.
