How do you replace front transmission seal on 2004 f-150 5.4?

To replace the front transmission seal on a 2004 F-150 with a 5.4L engine, first, ensure the vehicle is on a level surface and safely supported. Remove the drive shaft and any components obstructing access to the transmission, like the transmission pan if necessary. Carefully use a seal puller to remove the old seal, then clean the area before pressing in the new seal, ensuring it's seated evenly. Reassemble the components, refill the Transmission Fluid, and check for leaks.
