Cooter1967

2005 5.4L; I have changed all spark plugs and coil packs, replaced 2 injectors that I found leaking by in the process. My truck still drops out of OD into Neutral when the load is off and coasting. It also shifts hard when taking off if it is in OD, but runs great with no issues at all if it is in D. I had a transmission shop hook up to it an they say there is nothing wrong with the transmission, that it is getting the signal to shift. I am out of options to try. Love my truck but it is driving me crazy...
