Carolina Horsepower - View Single Post - how hard is rear main seal on a 99 4.6 auto?

On a 4.6 you only need to pull the transmission and the flexplate. No need to pull the pan like on a pushrod engine Ford. The seal just goes in a sub housing that bolts to the back of the block. The oil pan joint line is way below having anything to do with the seal. Just take a small drill bit and drill 2 small holes in the metal seal rim 180 degrees apart so that you can screw in a couple of medium size sheet metal screws in order to grab them with some dikes and pry the seal out.

I have never seen a leak from the sub housing to block joint, just mainly the rear seal.

Good luck fixing your leak.
