2003 e350 7.3 turbo Diesel...
2003 e350 7.3 turbo Diesel (4r100) O\D Light is flashing constantly Truck doesn't want to move forward but reverse is fine hooked up a scanner to it and got the following codes P0705, P0755, P0743, P1754, P1711 have changed the solenoid pack, Shift Position sensor and Harness Plug on Transmission.
Checked Fuses 12, 20 and 34 in cab
Prior to changing these items I was only receiving PO750, PO755 and PO743
I'm guessing I have a wiring issue somewhere

H​ello my name is ***** ***** have 2 differnet concerns going on here, the electrical solenoids are all showing circuit faults, so a pinpoint test needs to be done to find out where the problem is. The no drive problem sounds a little more serious, however the shop manual states that no electrical concern can cause a no forward engagement. But I would like to see all the electrical fixed first, then if it still doesn't move, we can address that later. Has a pinpoint test been ran to try to find out why there are all the circuit fault codes?

Scott, I mis worded the question it does move forward but it appears to be starting in over drive or something, that's what I meant when I say it doesn't want to move forward, apologies I should have been more specific

Ok, not a problem, that makes more sense, when the OD light flashes, the transmission is in default mode, when this happens you have one forward gear and reverse. I believe once the electrical concerns are repaired, the transmission will hopefully shift normally again.

I will run the tests and get back to you with results

I would check for VPWR on pin 1 first.

Since all the solenoids are affected, this would be the most likely.

Looks like VPWR should be on #1, #12. at trans connector.

Scott, Thanks for checking back. I tested the wiring harness and found the issue to be the plug on the passenger side that plugs into the valve body. this corrected that issue but presented me with a new issue lol now I have no power to the starter when trying to crank over engine.
anyway testing the plug ends worked thanks

Thanks for the update! If you need a wire diagram for the starter let me know and I will try to get one for you.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.
