There are two different Ford part numbers due to changes in the case fittings and vehicle applications. These seals will fit all applications regardless of assembly part number. Care must be taken when disassembling the fitting from the tube. One O-ring is used as the retainer and will be destroyed upon disassembly. Two O-ring seals are used to seal the fitting to the tube. When reassembling the tube, the use of a lubricant to ease insertion of the retaining Oring is strongly suggested..."

DTC 27, 29, 452, P0502, P0503, PO716, PO718; Insufficient input from VSS.; "...A more difficult problem to identify is a VSS that works, but sends out the wrong signal for a given vehicle speed. In some cases, a wrong reading from the VSS may still cause a code to be set. For example, if the VSS signal tells the computer the vehicle is traveling 60 miles an hour, but the throttle position sensor and MAP sensor tell the computer that the engine is idling, the computer will be confused. And a confused computer should set any of the following codes: Ford 27, 29, 452. On a vehicle that uses the VSS as a safety device, a defective sensor may send out a wrong "too fast" signal, shutting down fuel flow at the wrong time. Although this doesn’t happen often, it can be a difficult problem to identify. The customer will probably describe it as a random or intermittent sudden loss of power and poor performance, onlyto have the engine resume normal operation. Routine diagnostic checks of the engine in the shop won’t show any problem because there isn’t a problem with the engine or the ECM..." read more

If you have a shudder under load it could be a problem with the converter clutch, or it could be due to a problem with the EGR system causing the engine to misfire under load. If the converter clutch is unlocked and slipping the converter slippage can mask the misfire, and when the converter locks the misfire is noticable because the converter slip is gone. I would definitely take care of the EGR system first since it can cause misfires, and is likely to be much less expensive to repair than a transmission problem..." Page 2

The variable-force type solenoid is an electro-hydraulic actuator combining a solenoid and a regulating valve. It supplies electronic pressure control which regulates transmission line pressure and line modulator pressure. This is done by producing resisting forces to the main regulator and the line modulator circuits. These two pressures control clutch application pressures. Failed off — maximum electronic pressure control pressure, harsh engagements and shifts. May flash transmission control indicator lamp.

DTC 628; "...code 628 can be caused by a mechanical problem or electrical problem. First thing to do is to check power to the solenoid connector at the transmission. These solenoids are 12 volt solenoids, not 5 volts......I have attached a few pictures for reference. Unplug the transmission connector and check the VPWR wire for 12 volts first with the key on at the harness itself. Then if OK, check the solenoid resistance with an OHM meter on the 200 OHM scale through the pin on the connector coming out of the transmission marked TCC & VPWR pins. Should be 0.98 to 1.6 OHMS as MTB has said. I usually used a special transmission tester tool, but this is the only way you can do it. I have seen many of these code 628 in the past, and I'm sorry to say 95% have been internal Mechanical failure. These tests for the solenoids are only going to tell you if the solenoid is open or within spec. It will not tell you if a piece of junk is stuck in the solenoid causing it to bleed pressure to the TCC, therefore giving you a rough running engine, shuddering feeling or stall in 2nd, 3rd, or 4th gear caused by the Torque converter clutch being applied at the wrong time..."

DTC 628; "...I did things in a stupid-simple way when the 628 came up: I tapped into the TCC line, and attached a voltmeter between that line and chassis ground. While driving, I could watch for it to go between zero volts (meaning the PCM was commanding the converter to lock) and battery voltage (meaning the converter should be unlocked). It sounds counterintuitive at first, but that's a matter of perspective, I suppose. Anyhow, if you see the PCM trying to lock the TCC and nothing happens to the engine speed, or if you can give it a little more throttle and the engine speed rises while it's commanded to lock, then you're assured a problem exists. If there was an electrical problem, then the PCM should also be giving you a code 627 as well. The 628 indicates excessive converter slippage. At a steady cruise, say your 60 mph, if you tap the brake the engine speed should rise slightly, and then come back down as the TCC re-engages. This condition can be intermittent, and it's more of a mechanical problem than an electrical one. The fix for a slipping TCC is to replace the torque converter and stator shaft seal, nothing more. You'd be out a little over a hundred bucks probably, and a few hours' labor, if you get one through a reputable transmission shop. I wouldn't buy anything but an OE-type replacement. You may even be able to get a Motorcraft/Ford replacement through a local dealership, but I've no clue how much their price would be..."

DTC 637 - TOT sensor circuit above maximum voltage possible causes: Damaged TOT sensor. Open harness circuit(s). Damaged processor. or the transmission was overheated. The transmission fluid temperature sensor is located on the solenoid body assembly in the transmission sump. It is a temperature-sensitive device called a thermistor. The resistance value of the transmission fluid temperature sensor will vary with temperature change. The powertrain control module monitors voltage across the transmission fluid temperature sensor to determine the temperature of the transmission fluid. The powertrain control module uses this signal to determine whether a cold start shift schedule is necessary. The cold start shift schedule lowers shift speeds to allow for the reduced performance of cold engine operation. The powertrain control module also uses the transmission fluid temperature sensor input to adjust electronic pressure control pressure for temperature effects and inhibit torque converter clutch operation during the warm-up period. Symptoms: Torque converter clutch and stabilized shift schedule happens too soon after a cold start. Codes P1783 or 657 indicate transmission fluid temperature exceeds 132°C (270° F), results in increased EPC pressure and torque converter clutch engagement. May flash transmission control indicator lamp. Diagnostic Trouble Codes: 636, 637, 638, 657, P0712, P0713, P1711, P1783.

Filter Clip Alternative; "... have seen many threads and received many pm's as of late speaking of the stay-put filter clip used to keep the filters from falling out of the pump in the e4od. there is an alternative to using this clip. it is more expensive but also has more benefits than just using this clip. you can get a trans pan from a 03 super-duty truck. this pan has little humps in the bottom to but up against the bottom of the filter and this keeps the filter from falling down. this pan also has a drain plug and extra capacity for 1.5 more qts of fluid. this pan also allows you to use the much better elastomer gasket. it is reusable and virtually leak-proof. much better than the cork design. it does require the use of a 4x4 filter..."

Identification; "...If the shifter has a P-R-N-OD-D-1 pattern, the transmission must be an AOD (applicable to 1980-1993 vehicles). If a 1989-1993 truck has an Overdrive Cancel Switch and a P-R-N-OD-2-1 shifter pattern, then it is equipped with an E4OD transmission. 1994 and later vehicles with four speed automatic transmissions will all have an Overdrive Cancel Switch and a P-R-N-OD-2-1 shifter pattern, but may have either an E4OD or a 4R70W transmission. All 4.2L, 4.6L and some 5.0L engines use the 4R70W transmission, while diesel, 4.9L, 5.4L, 5.8L, 6.8L and 7.5L vehicles always use E4OD’s. You can measure the transmission fluid pan to determine which transmission you have if identification information is not available.

When an expected signal value from a sensor is sent to the computer and is not within the computer's programmed specifications, "secondary" programs are activated by the computer to strive to protect the transmission from damage the improper sensor signal might cause to occur.
In other words, the computer is always expecting certain signal values from certain sensors i.e. the temperature sensor, the speed sensor, the throttle position sensor, etc. As long as these signals are what it would normally expect for the conditions and is normal based on all the other signals it is receiving from other sensors, it acts normally and accordingly..." read more

Lock-Up Delay Solenoid; "...The E4OD and 4R100 units are programmed from the factory to apply lock-up immediately after the 1 – 2 shift. Many of the units on which Transtar customers work have logged 100,000 miles or more and the vehicles they are in are not generating the power they originally did. As a result, if the lock-up is applied immediately after the 1 – 2 shift, the vehicle will have difficulty pulling itself through the gear. The lock-up delay solenoid will set the lock-up timing back just enough to allow the engine to increase its torque output and allow the vehicle to continue adequate acceleration. The on board computer controlling the lock-up clutch in an E4OD or 4R100 unit issues the command that signals the converter to lock up. Several seconds later, the computer checks to see that lock-up has occurred. The time from the signal until the computer checks back is called "the window." (See blue area)..."

No Start Troubleshooting in a 90; "...First thing to check is wiring. Between the large posts of your starter relay (it's not a solenoid) should be a smaller post with a wire attached. This is the wire from your ignition switch through the park/neutral safety switch (Or clutch safety switch on a manual trans, or MLPS on a 90 with an E4OD) that turns the starter over. Check this wire for cracks, open insulation, or anything that could possibly cause an open circuit. Next, check your upper ignition actuator. Find the ignition rod (on top of the column, running from the steering wheel down to the ignition switch at the base of the column) and make sure it's moving back and forth when you turn the key, through all positions. If it is, your upper actuator is probably not the problem. Lastly, check your ignition switch (again, at the base of the column). Manually push the switch back and forth through the different positions. Push it all the way forward (or down) and see if it will engage the starter. If it does, then your ignition rod is probably bent, which can be remedied quite easily. & If it's an auto, try starting in neutral or while pulling up on the lever while it's in park. If that works, look to a park/neutral safety switch/MLPS. If it's a stick, check the clutch switch. You could try jumping from hot to the small terminal on the starter relay to test it's operation. Sometimes new ones are bad out of the box. If it won't turn over when jumped to the small terminal, you'll know that it's a starter relay issue (Bad part, bad ground). If it does turns over jumped to the small terminal, then you'll be looking for something in the small circuit that includes the ignition switch & the park/neutral safety switch (NSS) Or clutch safety switch on a manual trans, or MLPS on a 90 with an E4OD. There should be 12v running from the ignition switch, thru the NSS/MLPS, to the small terminal on the starter relay. Disconnect the small wire to the starter relay (So it doesn't start by surprise, I'd pull the coil wire too). With someone holding the key in the start position, you should be able to read 12v between any point on that small circuit & ground. When you find where you lose 12v, then you'll know where the issue is..."; MIESK5 EDIT; changed a few terms such as changing solenoid to starter relay and deleting jumping large terminals on the relay.

1) The upper and lower valve body gaskets are new, and have light green stripes for identification.
2) The low/reverse clutch piston now has lip seals instead of lathe cut seals.
3) The pan gasket is now a molded rubber gasket instead of cork.

Pump & Overdrive Section Assembly Tips; "...It is recommended that an aligning band be used when assembling an E4OD pump. The alignment band will locate the outside diameters of the pump assembly but not the bolt holes. To align the bolt holes quickly and easily, install a 10 mm shank bolt as shown in Figure 1, during assembly. This will more precisely align the pump and make the pump to case bolt installation easier. Installing the overdrive components is most easily done as a complete assembly. Assemble the entire overdrive section on the bench. Then, using snap ring pliers, reach into the turbine shaft hole. Squeeze the pliers tightly to grip the assembly. Now lift the overdrive assembly using the snap ring pliers as a handle and install it into the case (Figure 2)..." Figures are gone

Shift Improvement; Electronic Pressure Control (EPC) Solenoid Circuit Modification; "...Basically, grab yourself one of these guys (nevermind the picture, just remember 50 ohms and 10W), a couple of Scotch-Locks and/or a couple of male spade connectors. Connect it between the Electronic Pressure Control Solenoid (EPC) line [White/Yellow] and the VPWR [RED? constant +12V] line. This isn't the right way of augmenting duty cycle for a solenoid, but it works, and it's pretty reliable. I'd suggest using a 100-ohm resistor instead of a 50-ohm if you've not made any improvements to the accumulator valve body yet...The resistor should be connected across the lines stated in post #6 in this thread. 100 ohms may be too high for some peoples' rigs, in which case you should a) try a lower value, and b) always verify the resistance of the resistor with a DVOM. Never trust the component just because it's new."

Shift Lever Replacement; "...To change it, you'll want to drop the steering column. This sounds more difficult than it actually is. There's four nuts that hold the column up. 1/2 head side. Take the plastic housing off, undo the gear select cable, drop the column. There are a couple of plates that hold it in place. Torx head screws hold the plates. Undo those, then the shifter will become loose. Wiggle it free. Install in reverse order. Now, I did not pull the shifter itself while the column was in the truck. So there might be a little more involved if you try to do this while the column is in the truck. If it seems tricky to do so without the column removed completely, then remove it. There's a bolt the attaches the the steering rod to column, shift cable and some wiring to remove.,,"

Shift Lever Stuck in Park (pic is gone); "...These (and many other) vehicles are equipped with a Brake/Shifter interlock for safety. This system requires the driver to hold the brake depressed before the shift lever can be moved from the Park position. There is an actuator (solenoid) on the left side of the steering column under the dash that disengages the shifter lock when the brake is depressed. In the event this system malfunctions, the shift lever may be stuck in the Park position. One cause of this complaint may be due to a faulty brake switch circuit. If you experience this complaint always check for blown fuses and brake light switch operation before proceeding with other work.

The Programmable Speedometer/Odometer Module (PSOM) receives a speed signal input from the Differential Speed Sensor (DSS) and uses a programmed conversion constant to convert the signal to the standard 8000 pulses per mile speed signal output. The speed signal output is proportional to the road speed of the vehicle. The Programmable Speedometer/Odometer Module supplies this signal to all components that require vehicle speed information Including the Speed Control Amplifier, the Transmission Electronic Control Assembly (TECA) (with diesel engine), and the Electronic Engine Control (EEC) Module (with gasoline engine). So it is possible for the PSOM to get a good signal and yet not send it out to one, or more, of the other speed signal users. If this is what they meant by a faulty cluster, then they are correct..."

Solenoid Overview, DTC (s), Connector Pin-Out Diagram, Operation Chart, etc.: "...The powertrain control module controls the E4OD transmission operation through four on/off solenoids and one Variable Force Solenoid. These solenoids and transmission fluid temperature sensor are housed in the transmission solenoid body assembly. All are part of the transmission solenoid body and are not serviced individually. Additionally, in 1995, the protection diodes that were on the solenoid body have been moved to the PCM. Refer to the following information for the functions of these solenoids. The four on/off solenoids operate in the following manner: When the solenoid is off, the fluid pressure feed is blocked by a check ball. The check ball is held in place by the solenoid piston.
When the solenoid is turned on by the PCM, the piston is pulled up, releasing the check ball and allowing fluid pressure to be applied to the check valves and/or other components controlled by the solenoid. The Electronic Pressure Control solenoid is a variable force solenoid. The variable-force type solenoid is an electro-hydraulic actuator combining a solenoid and a regulating valve. It supplies electronic pressure control which regulates transmission line pressure and line modulator pressure. This is done by producing resisting forces to the main regulator and the line modulator circuits. These two pressures control clutch application pressures.
Symptoms: Failed on — minimum electronic pressure control pressure (minimum transmission torque capacity). Limit engine torque (partial fuel shut-off, heavy misfire). Flashing transmission control indicator lamp.
Failed off — maximum electronic pressure control pressure, harsh engagements and shifts. May flash transmission control indicator lamp. DTC 624,* 625,* P1746,* P1747.* CAUTION: The electronic pressure control pressure output from the variable force solenoid is NOT adjustable. Any modification to the electronic pressure control solenoid will affect the transmission warranty. (*Output circuit check, generated only by electrical condition.) Torque converter clutch solenoid provides torque converter clutch control by shifting the converter clutch control valve to apply or release the torque converter clutch. Symptoms: Failed on — engine stalls in drive at idle low speeds with brake applied or manual 2. Failed off — converter clutch never engages. May flash transmission control indicator lamp. DTC 629,* P0741,** P0743,** P1743, P1742, P1744. (*Output circuit check, generated only by electrical condition. **May also be generated by other non-electronic related transmission hardware condition.) The Coast Clutch Solenoid provides coast clutch control by shifting the coast clutch shift valve. The solenoid is activated by pressing the transmission control switch or by selecting the 1 or 2 range with the transmission gearshift selector lever. In manual 1 and 2, the coast clutch is controlled by the solenoid and also hydraulically as a fail-safe to ensure engine braking. In reverse, the coast clutch is controlled hydraulically and the solenoid is not on. NOTE: On certain applications, the coast clutch is controlled by the PCM in the overdrive position (TCS OFF) in gears 1, 2, and 3.
Symptoms: Failed on — Third gear engine braking with (D) range selected. Failed off — No third gear engine braking in overdrive cancel. DTC 626,* 628,** 643,* 652,* P0741,** P0743,* P1754.* (*Output circuit check, generated only by electrical conditions. **May also be generated by other non-electronic related transmission hardware condition.) Shift solenoids 1 and 2 provide gear selection of first through fourth gears by controlling the pressure to the three shift valves;
Shift Solenoid 1: Symptoms: Improper gear selection depending on failure mode and manual lever position; refer to the Shift Solenoid Operation Chart. May flash transmission control indicator lamp.

In the later (I can't remeber which year, I think 94?) Ford removed the diodes from the solenoid pack in the trans and added protection in the computer. If you end up with a late solenoid pack and an early computer you will likely be buying a new computer. Going from memory which is a couple years old now, the early solenoid packs had a redish orange seal in the electrical connector on the transmission side, the later solenoid packs without diodes have a green seal which goes into the vehicle side harness.

Torque Converter Shudder; "...If the shudder occurs a) during the 3-4 or 4-3 shift at HEAVY throttle, or b) at 40mph in 2, OD OFF, and OD, or c) at the same RPM in every gear, or d) coasting, cruising, or in R, or e) during extended light braking, then it is NOT TC clutch shudder; The following is a list of common vehicle concerns that have been misdiagnosed as torque converter clutch shudder. For diagnosis of the following items, refer to the appropriate sections of the workshop manual and the Powertrain Control/Emissions Diagnosis manual (PCED).
Spark plugs - check for cracks, high resistance or broken insulators.
Plug wires.
Fuel injector - filter may be plugged.
Fuel contamination - engine runs poorly.

Transmission Control Indicator Light & Switch (Overdrive ON-OFF) Overview in 92-96; "...A transmission control switch and an indicator labeled OVERDRIVE is located on the end of the gearshaft lever. Press this switch and the word OFF will illuminate on the shift lever knob. With the word OFF illuminated, the transmission will operate in gears one through three. Operating in overdrive OFF gives more engine braking than overdrive and is useful for descending hills.
To return the transmission to the normal overdrive operation, press the transmission control switch again. The switch may be used to select overdrive or overdrive OFF at any time the vehicle is being driven.
If the transmission control indicator light is flashing on and off repeatedly, the transmission system is malfunctioning. The transmission will operate in a failure management mode with harsh engagements, firm shift feel, and abnormal shift schedule..." read more

Transmission Control Indicator Light (TCIL) Troubleshooting in 92-96; "... Several different complaints concerning the overdrive cancel indicator may occur due to a faulty O/D cancel LED. At times the light may simply fail to light, flicker erratically, or glow very dim. Tapping the shift knob lightly may affect the operation of the LED, causing it to work temporarily. These complaints are usually due to a faulty O/D indicator LED. To replace the LED carefully pry the cap off the end of the shifter and pull the LED/switch out. Slide the new switch into position and snap the cap back on. Note: Don’t confuse the above conditions with a steady flashing pattern of the O/D cancel light. A steady rhythmic flashing pattern indicates a malfunction has been detected by the computer.; Part #F58Z-7G550-A..."

Transmission Control Indicator Light (TCIL) Troubleshooting in 92-96; "... The flashing OD light is an indication of a transmission related trouble code in the Powertrain Control Module (PCM). When it has a trouble code related to the transmission it usually commands full line pressure to try to protect the transmission from damage. Normally this is caused by a transmission slip code. Have your computer scanned to see what transmission codes are stored. If it is a torque converter slip code keep in mind it could be stored from converter clutch slippage, or slippage in another transmission clutch pack ..."

Transmission Control Indicator Light (TCIL) Troubleshooting; "...This symptom could be caused by a couple of problems. One is the transmission is malfunctioning. The bulb in the switch at the end of the shifter is flaky. The wire that connects the OD switch/light at the end of the shifter is being worn at the column. Process of elimination. Codes to the computer and the light flashing in a "repetetive pattern" and consistent manner indicate a trani malfunction. A flashing OD light that is sporatic, has no pattern, is accompanied by a also sporatic OD engagement indicated that the wires are being worn and possibly shorted at the column. This is a common problem with these. The light flashing in a sporatic and sometimes on and sometimes off for longer periods indicated a bad switch at the end of the column. (my case)
Hope it is one of the easier ones. (Switch light or wires at column)..."

Transmission Fluid Temperature (TFT) Sensor"... The transmission fluid temperature sensor is located on the solenoid body assembly in the transmission sump. It is a temperature-sensitive device called a thermistor. The resistance value of the transmission fluid temperature sensor will vary with temperature change. The powertrain control module monitors voltage across the transmission fluid temperature sensor to determine the temperature of the transmission fluid. The powertrain control module uses this signal to determine whether a cold start shift schedule is necessary. The cold start shift schedule lowers shift speeds to allow for the reduced performance of cold engine operation. The powertrain control module also uses the transmission fluid temperature sensor input to adjust electronic pressure control pressure for temperature effects and inhibit torque converter clutch operation during the warm-up period. DTC 636, 637, 638, 657, P0712, P0713, P1711, P1783..." READ MUCH MORE

Transmission Oil Temperature Sensor (TOT) Removal; "...It is located in da Pack between Converter Clutch Control (CCC) Solenoid & the Coast Clutch Solenoid. Once you remove the pan locate the sensor in the valve body and remove the electrical connector very carefully. The sensor is about the size of a pen cap. To remove the sensor carefully unlock the stop tab and twist it, pull down to remove it. It comes out before a full quarter turn is made. Put it back in the reverse order. When you get the sensor to come out be prepared to catch the trans fluid that follows behind it, you will get less than a quart out of it. It is located in da Pack between Converter Clutch Control (CCC) Solenoid & the Coast Clutch Solenoid. try the connections first. They are usually the root of the problem..."
