JUSTFISHING Posted July 9, 2019 Share Posted July 9, 2019 Having intermittent trouble with PTO on our 2016 550 power stroke automatic transmission shift in and will shift itself out after a while sometimes you can shift back on sometimes not for a while. anyone else experience this and found the fix. thanks Quote Link to comment Share on other sites More sharing options...
Southwest Towing Posted July 15, 2019 Share Posted July 15, 2019 I have a 2016 F550 6.8 V10.I had a different problem yesterday.When I turn the PTO switch on either it would not engage at all or there would be a long delay.I disconnected the 2 plugs that go into the PTO and the pump and sprayed some WD40.Now its fine.Worth a try.

Thanks will keep that in mind . we changed out the rocker switches thinking they may be getting worn out time will tell if that was the fix.

goodmichael Posted July 29, 2019 Share Posted July 29, 2019 Have you ohmed out the wiring? Sounds like a corrosion/resistance problem. Quote Link to comment Share on other sites More sharing options...
