Pez, I Had my pump, o ring, and torque bolts replaced also and it is back at the shop because it continues to leak also. This is my third time bringing it to the dealer for this issue. last time, which was a few days ago, they tried to tell me it was residue from when they changed the pump 3 WEEKS ago. They cleaned the inside of the bell housing and took it for a 20 mile ride and called me to pick it up and said it was not leaking. I put around 40 miles on it and came home and took the dust cover off of the bellhousing and swabbed the inside with my finger and ill be darned it was still leaking. The leak is very slow. I was so pissed. I called ford corp. and they said they were going to take it to the next level whatever that means. Please let me know if the y figure out what it is and i will do the same. Good luck! By the way when was your truck built?
