Pulling motor and tranny without leaking tranny fluid all over the place making a mes

I have a shelf full of spare transmission slip yokes. If it's 66 or newer - once the driveshaft comes out, the tranny will puke fluid out the tail when it's tilted. Earlier should be fine with the flange on them. Use a peice of 3/8 rubber hose and clamps once the transmission cooler is disconnected and connect the two cooler lines from the transmission together.
