I have a 2005 ford f250 with 5.4 liter engine 4x4, while I was driving I started to notice a scraping/grinding sound that would only happen when I accelerate but when I let off the gas itd go away well one day on the way to work I lost all gears no forward reverse 1 2 3 or 4x4 towed to the shop they said transmission well I replaced and the same exact thing happened not even 400 miles after the "new" used transmission was installed what could be causing this to happen? Computer related problem? Or torque converter? Its not likely that all ears go out at once and if it’s the torque converter is my transmission still good?

The torque converter from original transmission was used. The warranty stated to use original TC. As far as loosing all gears at once I'd think it's either the TC or TMS issues
