    Need help ASAP, truck is dead!

    Have the batteries tested. If the voltage drops that fast there is a dead short someplace. What ever is failing should be extremely hot.

    1990 7.3 idi e4od transmission issues

    Check the TCM for water damage. (inside left kick panel) The TCM needs a good tach signal in order to work correctly. No signal or erratic signal will cause shift issues. Starting in a higher gear is usually no power to the TCM. Check the TCM relay. (under hood left fender)

    E4OD blues

    You got it. VSS signal goes to the PSOM, speedometer, then to the TCM. Pre digital days (89-91) the VSS signal went straight to the TCM.

    E4OD blues

    VSS is good, so I would be going for the PSOM.

    Really wishing I had a zf5...TPS sensor.

    I wouldn't worry about the max spec. Don't exceed 4.5 volts. When setting the TPS stay within the min/max spec. Do a test drive, if it shifts good leave it. If you don't like it, give it a little adjustment. Most times it can take a couple of tries to get it right.

    Really wishing I had a zf5...TPS sensor.

    CPS is on a PSD. IDI uses a tach sensor. The TPS could could develop dead spots causing shift issues up or down range. To test for this, use the volt meter and test the full sweep. There should be no jumps or erratic changes on the meter.

    ECU?

    TCM or Transmission Control Module. It has no function for the engine just the tranny. You can get re manufactured from the big parts stores.

    Possible torque converter?

    Check the fluid level.

    E4OD TC engagement

    If it does lock it should unlock fairly quick. The TCM is programed to keep the engine from bogging down and burning up the converter clutch. Reset the TPS and try again. Hit the OD OFF button before you hit the grade. Sometimes this helps. The TCM program isn't the greatest.

    E4OD TC engagement

    ATS is a decent converter, it should be a multi disk unit with a billet cover. A converter will run locked or unlocked. Never half locked. If it did run half locked the disk will fail quickly. The converter should lock when cruising. Unless the RPM is below 1200. Climbing a steady grade...

    I have watched a few. :)

    how to go on with my E4OD

    Unwanted things would be aluminum planetary carriers. Early center support bushing. Non hardened sun shell to list a few things. There are a number of upgrades for the 89 model year. enough to warrant a book of updates.

    how to go on with my E4OD

    Stock is a single disk with a stamped cover.

    how to go on with my E4OD

    Yes for a stock converter. With a multi disk billet cover this is optional. A quality after market converter will take a much larger load than a single disk stock unit.

    E4od US shift quick 4 stand alone transmission controller available

    89-91 use a TCM with a gear driven VSS on the tranny or transfer case.

    The PSOM may have quit working.

    Engine Issue or Torque Converter issue?

    Yes it could.

    1998 E350 power stroke speed sensor on eo4d tail housing purpose?

    89-91 1356 transfer case have a VSS provision. It works off a worm and gear to drive the speedometer cable and VSS. 92 this was no longer needed.

    Engine Issue or Torque Converter issue?

    Before going crazy with the tranny. Fix the electrical issue first. Any voltage drops will make the E4 go nuts. The TCM is not tolerant of fluctuating voltage. I would start with the alternator because the TCM or solenoid pack are not able to draw down that kind of power.

    1998 E350 power stroke speed sensor on eo4d tail housing purpose?

    That sensor is the VSS. The PCM uses that sensor for the speedometer and controls shift points.

    E4OD Behavior

    The 5th gear feeling is the TC locking. The go peddle isn't slammed to the floor, you will get this response. When setting the TPS. Set it to spec first. Then test drive. You will end up resetting it, because the factory TCM tuning sucks.LOL

    Used 7.3 Engine

    Another possibility is a cracked block.

    1992 E350 7.3 newbie trans questions

    Any diesel two wheel drive E4OD from 89-94 will work. The only catch is the manual lever might have to be swapped out. 89-91 are the rod type linkage.92 on are cable driven.
