I am getting ready to put my new engine and rebuilt AOD trans back in the car and I just thought I would double-check to make sure what fluid would be best. I am assuming that Motorcraft Dexron V would be what I would want but I am not 100% sure. Are there any additional tips about put this back in? Would it be best to fill the transmission up with fluid (as well as the torque converter) before I connect it to the engine? Any other thoughts would be appreciated.
