Pulling Slant 6 Without Removing Transmission

If you have the head off how are you supporting motor. The lift points are on the head first hole on the front of head is engine only you attach both front lift point and back to pull engine and tranny together. Use those threaded holes you cant go wrong. Thats not me thats factory procedure. I think its easier to pull both at the same time just my opinion. Sounds like you have tension on somewhere or a bolt. I have slapped mine with a rubber mallet once or twice and they seperated when leaving the tranny in and removing the engine alone. that was just from years of being connected. Do you have anything supporting the transmission? Good luck
