I have a 2003 F250 6.0 with a 5R110W trans . After it warms up, it locks up and slides to a stop. I had it rebuilt and it still does the same thing , does anyone have any ideals please

 

Who rebuilt it, and do they stand behind their work? Why it still does this after a rebuild would be something the rebuilder should answer.

 

The OP replied via message:

"A ford Auto trans teck built it and even the ford tecks back east cant figure it out"

If they can't figure it out, then they need to pull a new trans out of their pocket and get your vehicle running. You need to adopt a tough stance with them. Nowhere is it allowed to "repair" something, take the money, and leave the customer inoperable.
