welcome to FTE, 9173.
under the hood,near the drivers side hood hinge is the trans port for connecting a code scanner.just an old school OBD1 is all that's needed,for example;
just about any auto store will carry them too.example;

for the diesel,during KOEO,be sure to hold WOT during the scan to avoid false code 23 - fipl/tps.
with those codes,it will point you in the right direction.sometimes things are obvious issues where you don't even need to scan,such as for example,if the tach doesn't work or blown fuses under the hood,or in the cab.
every E40D owner should have an old OBD1 scanner anyway though.

Howdy. Not sure about what year models this affects but a buddy thats pretty slick on 7.3 stuff told me that on the e40d if you have flashing light and shifting problems first place to check (other than transmission fluid) is the dome light/third tail light. Apparently they share a ground wire or something and problems at the light can goof up the tranny.
I was running my 97 around and wasn't aware the alternator was crapped, when the two batteries started to give it up my symptoms were dim lights, hard shifting and flashing o/d light.
good luck
