I have not had to mess with it on any of my vehicles but I believe it is on the solenoid pack in the valve body. I think I would make sure it's not the wire in between first before going after that.
'90 E4OD wont shift properly

Just a thought, I had an E4OD years ago that had an intermittent code 99
It was a short in the EPC solenoid in the trans. (Thats the line press control solenoid)
When the code is active, the PCM cant regulate line press, so it goes into FMEM, (a specific type of limp mode) at this time, it limits torque by cutting 1 bank of injectors (half) and stays in (I think 2nd gear)
99 usually only sets as a memory code.
If it resets, I would strongly consider replacing the solenoid pack in the trans.
Hope that helps
Cheers

Thank you, I will try to mess with it soon. Our heat index suppose to get in the 100's.
I checked all of the wires underneath. So I guess it is the solenoid pack. That will have to wait until next year.
K, after I did some other stuff. I checked codes again. Koeo code 10,11 which is good.
Koer code 10, 44. 44 was on there for years.
However it will still not go in overdrive.

44 Secondary Air Injection system Inoperative (right side). I wouldn't think that this would effect shifting.

Try this web site for codes, now keep in mind the codes can be different things on different vehicles on the EEC-IV system. Are you getting codes with a code reader? because a 10 code that I can tell does not exist. Going all the back to the beginning, the old "KISS" way of doing things. Is you trans fluid level low or high? because both of these will cause problems with the E4OD.
Yes, I am using a code reader. 10 is suppose to be a good connection to reader.
The transmission fluid is on the dot and not burned.
The last time I drove it every day was last year during the summer. I parked it for about 6 months because of surgery. When I started driving it 2 months ago that's when it wouldn't go in overdrive.

Updates? TPS & IAC go bad? Or?

Nothing yet been busy. I think I will wait until October and redo some wiring, check sensors and take solenoid pack out and check ports. Unless I can get more of me to do all the other stuff that I deal with.Updates? TPS & IAC go bad? Or?
