It's Not Wanting To Crank In Park And Sometimes It Won't Shift Into Over Drive. It's Real Intermittent. I've Also Got A 93 F250 Having Transmission Issues. Im Going This Weekend To Try To Pull Codes On Both Trucks. Can You Still Pull Codes If The The Check Engine Light Isn't On?

Do you know how to pull the OBD1 Quick Test (pull codes) procedures?
Codes will not tell you anything about the starter circuit issue. Unless you execute the transmission drive cycle test properly, they probably won't tell you anything about the transmission issues, either.
See factory service manual for explicit instructions.
Only if there are codes set that can be pulled. Besides, transmission faults don't turn on the MIL, if anything, they activate the TCIL.

Code 67 (CM & KOER): Transmission Manual Lever Position Sensor circuit out of self test.
That is the first one that came to mind....
I will agree the MLPS may be slightly out of adjustment and not trigger a code, but why guess?

I did not know it was possible to get codes on a 1990.
How would you do it?
Did they even have codes back then?
This question has come up before and I do not think anyone was able to get codes out of one.
I do not think they ever had the OBD-1 system on these trucks. They used some off the wall system.
What engine does the 1993 have in it?

I was ready to ask if you lost your mind...then I saw the OP has an IDI 7.3...that gets me every time. Darn diesel trucks have to be so different from the gassers....

Yes they did.
Sure they did. That off the wall system was called EEC-IV, the same system the gas engine vehicles used. But this system only operated the transmission.

I am not that up on the E4OD with the TECA transmission control and I knew they had a test plug but reading other posts no one was able to get codes out of it.
I know no diesel ever had EEC-IV (Electric Engine Control 4) as it is stated in a lot of manuals.
But was the codes from the 1990 TECA with a analog meter the same as the OBD-1 two digit codes for the E4OD. I take it they were.
The off the wall system was something between OBD-1 and OBD-II in the mid 90's before they started using OBD-II in the diesel trucks. At least such a system is talked about in the in the Ford shop manuals.
The only diesels i have been around (other than the 18 wheelers I used to work on) is my sons 2002 F350 and my 873 Bobcat. We did use the OBD-II reader on his truck.
Yes I still learn something new every day even at 71 years old.
I will go back to helping on the gasser trucks and leave these to you Diesel folks.
Sorry if I up set this thread.
