you were not told wrong.those are possibilities.in the vast amount of possibilities,those are some of the more rare ones and not a decent starting point,but true enough phrase in it's own right i suppose.
the codes and a new thread are the best places to begin.

E40d transmission.
I swapped tge 300 6 out of my 95 f 150 to a 5.0 from a 89 f150. I was gonna swap the tranny also but the harness wouldn't work so i left the e40d in it. I was having issues with hard shifts before and they seem to have gotten worse. I changed harness for the transmission still having the same issue. I replaced the cluster and now the lights are flashing Speedo bouncing shifting crazy think it is the shift solenoid but im not sure anymore. Any help would be greatly appreciated.

What PCM are you using? I assume you changed it to one for the 5.0L because one from a 300 won't operate a V8. Did the PCM you installed come from a truck with an E4OD? If not, that's your problem. You MUST have a PCM that operates a 5.0L/E4OD. No other PCM can be made to work.

Y'all Confused Mark, Mark that was 2 different people posting, zapper didnt answer you, then dwriedt chimed in with their question, so it falls under zapper needs to answer Marks question, and dwriedt should take his back under warranty, and tell them it isnt fixed, because thats a lot of money spent to still have issues.
