I have a "06" F350, with 106k miles. just out of warranty.... Figures...!
It has the 5r110w torqshift, while traveling down the highway this winter "COLD OUT" about 55 mph I slightly accelerated and the tranny felt like is shifted into neutral. I pulled over and stopped. If I shifted it into reverse or forward, it would rock the truck slightly in each direction... Slightly. pulled the SCT tuner out and hooked it up to get DTC codes had a 730 and some others, read on the forums and it said that usually caused by Coast/Direct solenoid. I lost the paper with the other code's. I have replaced the internal wiring harness, and the "A" and "D" solenoids, both filters disconnected the batteries for a day. Restarted it and it does the same thing. Pressed the tow light and it starts flashing. the only other thing I found was the ECM controller wiring harness closest to the tranny was not locked down completely, but it was still seated, just the locking mechanism was not locked. Fluid was a little dark red when drained, and round magnet in pan was holding some very fine grey material. Checked the codes again and no codes.

I am the second owner of this truck so I do not know if this magnet was added or original. It looks like a washer about 1.125" inside dia. and 1.5" outside and about .250 thick.

Now What do I do!

Is it a different solenoid?

I read something about a snap ring.

Man o man, this truck is like an accident prone child. Something is always going wrong.

Does the tranny fluid smell burnt? Sounds like you (or the other owner) have neglected this tranny and it is toast. Good luck!

You said you found a code 730, and that means nothing and is an invalid code. A valid code would be a T0730, if it exists. Codes are preceded by a letter and that is needed to find the code.

Dave :dunno
