Of course, but we are NOT gas engine experts. You would do better at a Gas Truck Forum. This site is called Super Duty Diesel for a reason.

he took a shot..
anyway..

that is correct.

The transmission needs to be separated from the engine to do this.
Triton engines use a knock-in rear main; similar to say, an axle seal.
