After unhooking everything to pull a motor out for a clutch change, I found that the motor would not move even a 1/4 inch off the trany. With the trouble light I finely found a hose branching off the oil drain and going back under the trany bellows and out the side of the floor. Someone in the past had the great idea of separate oil drain system but forgot that it is almost impossible to remove the motor as you can not get in to disconnect the hose. They must have had the trany out when they did it.
No way I can rehook it back so I have removed the system. Sure had me scratching my head for a bit!
