if the motor is apart from tranny itll have a 6.0 stamp on the right side(looking at back of the motor) there should be one on the front too if im not mistaken.
tranny pan i have no idea, isnt it the only tranny that doesnt have servos? on passenger side of tranny there will not be a circle like cap towards bellhousing, thats where the servos go.
worse thing get the number off of the head and call the dealership
