<TABLE><TBODY><TR><TD vAlign=top width="100%">i am a new member to this site and my first ford truck.f-350 4x4 v10.wanted to know if anyone has had a problem at highway speed when the converter is trying to go into lockup and hearing a loud rattling noise and vibration? took it to the dealership and they replaced the torque converter solenoid but still have the same problem.

It sound like the problem is in the converter lockup clutches, I'm thinking a new converter is in our future.
