    I assume that you know if you have taken the car to a transmission shop, they would have charged you for a rebuild and maybe only fixed the actual problem, if you are lucky.

    I am curious if the ones around here would have even figured it out... they would have rebuilt/replaced it, then stood there and dropped a load when the tranny did the same thing afterwards...

    That kind of thing probably happens plenty often. Then they continue looking until they find the -real- problem (and maybe replacing parts you will be billed for) or until you have the car towed somewhere else - if you can even afford to pay the bill at that point.
    My impression of most "transmission repair shops" is that they never actually repair a transmission. They install a 'rebuilt' that they buy from a wholesaler, hoping that will fix it. I dont want to picture the "transmission repair industry" as being incompetent or crooked: Its just that they can assume most customers know nothing at all about transmissions.

    I do. They are about as honest and ethical as realtors and politicians.

    I think Intuit is spot on with the assessment of more *weak* grounds in this car. If I had this problem I would take apart all the ground points and do a wiggle test on each ground wire and connector. In my 43 years of experience in industrial & auto electronics I have found bad ground connections to be a major problem. In many cases a ground problem can reappear in an intermittent fashion.

    I am now having the same problems with my 93 lx wagon. except I have no reverse lights and headlights do not phase it. just stays in limp mode. will switch into overdrive for about 2-3 minutes when I leave for work in the morning and jump back into 3rd like i just pushed the pedal to the floor. my question is where did you locate this wire driver side or passanger side of the trunk? I plan on looking for a weak ground like you guys suggested first hopefully that will be the problem.

    I ran the codes and determined its
    KOEO:
    641

    (O)

    Transmission solenoid/circuit failure Shift Solenoid 3 – Transmissions

    KOER:
    111



    System checks OK
    How can system check be ok but have a failure on shift solenoid 3? Does anyone know what color the wire is going into the trans to shift solenoid 3 so i can test it with an ohm meter??? PLEASE!!!! TIA Guys

    I think the 'system check' just indicates that the PCM has run through its Power-On-Self-Test, and the PCM itself is okay.

    ok so that seems relatively simply. but another link off that to the same topic showed code 641 to be solenoid 3-2? i thought there where 2 solenoids? 1-2 and 3-4... does this mean theres a 2-3 also it would make sense. and i tried to use my ohm meter on the pins but had no idea what i was looking for but nothing stood out as "weak".. i say either 4.79v + or 12.0v +

    Denisond13: can you confirm if i can be dropped from bellow the car? worried about whats under the valve body that i cant see... I know you've been in and out of these things a bunch of times.

    ok so ive figured out i can drop the entire valve body with no problems. I have also found the 1-2 2-3 and 3-4 shift solenoids on rock auto for 159$ so i think im going to order the set and swap the solenoids. i wont be able to do it this weekend i have to work so maybe the next weekend.

    Yes you can drop the valve body just keep track of what bolts go where, some are longer than others. You may get lucky and not have a problem with the black paper gaskets but sometimes they do break apart when dropping the valve body.
    On the transmission I am working on this is what the gasket looked like on the valve body.

    Godvain: Be sure each of the tiny filters on the inlets of the solenoids are clean.

    Unplug the connector at the top of the transmission and check the solenoids that way. Report back the ohms for each of them and report back. I would only replace the bad solenoids (except for the 2 pack, which I would replace as a pair). I do recommend getting used ones from a JY because they are really cheap there and if you can get them out there first, it will be very easy to install in your car. The junkyard only charged me $6.50 for my solenoid. Add tax and $1 admission to that.

    Ok I believe I've found the problem. I was messing around with it today and the white plug on top of the trans was GUNKED up with allot of stuff in it. So I bought a can of electrical cleaner, sprayed the tar out of it and several other connectors pulled the battery cables and reset the codes. I haven't drove it yet but I got 111 on koeo and koer. Bad thing is I can't find any escorts in the junkyards around here but rock auto has the 1-2, 2-3, 3-4, TC lock up solenoids as a kit for 150$ worse case scenario. Thanks guys for always helping me, atleast we can add this to the list of limp mode resolutions. **Fingers crossed**

    So you fixed it, but didn't test drive it???

    If you do happen to need solenoids, I still recommend the junkyard method, even if only to boost your confidence in the whole procedure.

    Not yesterday, had to get the yard mowed but been driving it all day getting on it hard with double step downs on the passing gear ect. works just fine. i pulled the codes after yesterday and it was nothing but 111 in KOEO & KOER. So I just had a little faith in the squirt and she showed me why shes been so good to me for the last 3-4 years. only thing weird is when i start it up idles fine. stop at a redlight idles fine. put it back in park to shut it off and the RPMs raise slowly, I watched to see how far itd go but I shut it off at 3000rpms because I felt it would only climb more. Still need to figure that out but im exploring with it. Cant be the throttle sticking cause every where else is fine and it only does it when i want to shut it off. I think shes telling me to shut up and drive lol jk idk

    I know right lol I was thinking same thing surely there's no way there related but I'm hoping it'll fix it's self. It didn't do it this morning but it'll probably do it when I pull up t the house tonight after work just case I said something.
