In 1982, Ford Motor Company will introduce its all new fourth generation electronic engine control system, EEC-IV, on selected applications starting with the 1983 1 6L EFI engine on Escort, Lynx, EXP and LN7 passenger cars. The EEC-IV system represents a new state-of-the-art in electronic engine management. EEC-IV was planned and designed to provide the system capability, flexibility, and cost/reliability benefits to satisfy Federal and consumer pressures for improved emissions, economy, and performance for all Ford powertrain and fuel delivery systems through the 1980's. This paper presents an overview of the electronic engine control technology trends which led to the development of EEC-IV, a review of EEC-IV capabilities and features, and a projection of future powertrain control requirements which could potentially be contained within the design capabilities of EEC-IV

Oh boy, i've been down the same road before. And it's not pretty. Check on the drivers side of your E4OD. You should find a little black or dark colored box that appears to be bolted to the side of the transmission. Look on top of this little box and you should see some wiring in a pigtail coming out of the top of this box. unplug this pigtail. Wait a few seconds and plug it back in. But, when you go to plug it back in, make sure you push down on it with a decent amount of force (not enough to break somthing though).This should fix your problem. Since the E4OD's overdrive is electronically controlled, it won't work right if the computer(i.e. the little colored box on the side of the transmission) isn't getting all the information it needs. If none of this fixes your problem, the transmission computer ( I think that's what it's called, I'm not 100% for sure on the name) needs to be replaced. And if that doesnt work, then you're probably gonna have to replace the transmission.
For three weeks the transmission has been like new since replacing the solenoid assy. Yesterday it shifted crazy again while running errands. I got on the highway today and the original issue I started this thread with is back. At 60 with cruising throttle it is fine. Let off the gas just a little and it down shifts from OD to 3. Give it a little gas it it up-shifts into OD again.
Checked warm fluid level idling in park on a level service. It is perfect between the two holes.
Pulled codes.
1. 622 Shift solenoid #2 circuit failure has returned again in KOEO.
CM has ..
2. 211 Two or more successive erratic Profile Ignition Pickup (PIP) pulses occurred, resulting in a possible engine miss or stall.
(died on me last week and restarted immediately after pulling over).
3. Now have a new code 628 Converter clutch Lock-Up error (E4OD) in CM
Here are my questions...
1. Why would a new shift solenoid pack fail in three weeks? What else could it be?
2. I have fought 211 for years and don't want to discuss it in this thread.
3. Would a stall driving down the highway cause the 628 converter error code? The converter seemed fine to me during the three weeks of like new transmission.
Thanks you for your thoughts.
It is not a Ford part, no oval, no part number. It does have the identical Pat. Numbers as the Ford original. Circuit board holes match. Picture of the installed on is on page 2.
The original ford part is E9TP-7G391-CA and I may have to go shopping again. Any more suggestions?
Update...bought a genuine Ford solenoid pack and installed it. It did not correct the problem. Ordered a pigtail connection with short wires from Ford. It is the connection that plugs into the transmission at the right rear into the solenoid pack.
The plan for this weekend is the remove the harness and try to find a bad wire/connector. Pull the wire like a bungee cord and check ohms.
I am stumped and asking you experts...I replaced the connector today and it did not correct the issue. After warming it up good I took it for 45 minute test drive. Set OD button to off. It did great until finally eased up to 57 mph and it started jumping between 4 and 3 again even with the button at OFF.
The wires near the solenoid pack connector looked good and no corrosion on the connectors. Cleaned, blew and greased them well.
So???? VSS, MLPS, PSOM, harness or take it to a transmission shop? Codes were 111 before test drive.
It is back!!! Here is my code again...KOEO 622 Shift Solenoid #2 circuit fault. CM 111.
You are correct. Every Time I found a sensor not performing to the chart and replaced it the transmission improved over the last couple of years. I even replaced before they got bad enough to throw codes. The 211 is intermittent and has only raised it's ugly head after many months of sitting outside but is gone now. The only code in KOEO is 622 and the CM passes with 111.
I replaced the distributor 3 times.
Transmission was like new until the sudden 3-4 jerking.
How do you look for a stuck valve when the solenoid pack is one assembly of several valves?
Last time I dropped the pan (40 miles ago) for a genuine Ford pack everything was shiny clean with only about Q-tip size or less accumulation on the magnet. I don't suspect anything has become discombobulated.
Hunting every 2-4 seconds. Worse at 57+ mph. No throttle drops into 4 even with OD button off. Light throttle, back into 3. Then occasionally drops into 4 at 1000 rpm and slow speed.
In other words, the trans tries to shift to the higher gear but gets a signal that torque is being lost so it shifts down, So it's internal clutch plates slipping too much
So if you have replaced the solenoid pack and the same Code is rearing its ugly head, the issue is still in the same location according the the ECM. Since the engine isn't affected, the ECM is most likely NOT the issue. However, you have wiring and electronics between the ECM and the transmission. If the Code is being thrown it means something is keeping the ECM from getting the correct information and if the parts at the end of the circuits that the ECM "says" are screwing up are brand new or "tested good" then the problem, by process of elimination, has to be between the ECM and those parts in the wiring or connectors.
