that's an early indication that its on its way out. I have been thru plenty of them. I went with a good low mile used one and an upgraded torque converter from RCD. It has been great ever since.

With that many codes I suspect something happened to damage the wiring harness.

So next question when buying a used trans is there something to look for how can I check it?

I'll bet dollars to donuts that if you put another trans in this truck it's going to do the same thing as the old trans.

Have you looked at the harness? Does it show any damage? Does it look like it caught on something and got yanked? Take the connector off the passenger's side of the trans. Is there oil in it? Is there corrosion? Was it loose?

Oil looks and smells cleans I'll look at the harness when I get a chance

I believe Mark means is there any oil in or on the harness and connector.

Mark Kovalsky · May 14, 2016

Yes, that's what I meant.

Connection looks good no fluid no corrosion

Also the truck before all this happened would go slow into reverse and drive. Thanks mark for the help

Update again: drive the truck around the blocks couple times got into it and it shifted fine it shifted into 3,2,1 I came home to park it and go in reverse and it would idle back I had to push the peddle to get it to move.

you have to trust the person or place you get the used transmission from. I was buying them for super cheap and they were unknown to me... I went thru 3 or 4 before I got one from my buddy Seth... he said it was a low mileage one and I trusted him, it hasn't let me down yet. with that said, he may have others for sale if youre interested. message him co04cobra (Ted Davis Auto)

Thank you for the reply we are gonna try and replace the D solenoid and see what happens but if it doesn't help we're gonna try and find a used one hopefully it fixes it

I run the upgraded one in mine... it went bad after about 150k and had to replace it with no issues. I hope that works for you....

Where did you buy it from? Ford? And is D&A in the same sequence or should I change both? I'm a rookie with this

I just bought the upgraded direct drive one from Rykan Holder Diesel...hes great to work with. I also run his injectors and he installed my Barders Turbo. Hes based out of Florida now though, but ships quickly
