Transmission help
I have a 2006 F350 SRW 4WD 6.0 with 127000 miles on it. A couple of weeks ago it, pulling out of my driveway, it hesitated and tow haul started flashing. I had codes pulled and it showed P1780, P0751, and P2700. After turning off, codes were gone and tow haul off. Ran fine since then every day. Yesterday while going about 50 mph it started acting like it was in neutral (revving up), nothing happened when mashing the accelerator. Coasted to a driveway and truck would not move, only sounded like it was in neutral. Any ideas??

Your problem from the codes you listed is a sticking shift solenoid A. That will also cause the P2700 code. The P1780 code means either the tow/haul button doesn't work, or the person running self test didn't press the button during the test like they should have.
Sometimes you can clear a P0751 by changing the fluid and the external filter. Fresh fluid can unstick the solenoid. It may not always work.
