    Hey Mark I am new to the forum but have been all over the sight trying to figure out my truck. I have a 02 Ford Ranger XLT 4wheel drive, 4.0 liter,with 158,000miles on it. I had no problems at all with it till recently. I go out to go to work and it shifted fine into first and second gear but when I go to get on the highway I find that it revs all the way to 3500 to 4000 before it shifts into drive but will not shift into overdrive and my O/D light starts flashing. I now have a check engine light on as well so I take it to the shop to put it on the computer to see what they tell me. I am told it's the output sensor on my tranny. Well I buy the part but can't get the size for the bolt right to get the old one out. I have tried a 10 n 8 mm but won't work so I am at a loss here any help would be appreciated thanks. You seem to have a lot of valuable input it would be much help any words of advice

    Hello Mark,

    You are a highly sought after guys I am hoping that you might have some insight. I have a 2006 5r110 with only 40K on it. Every time I pull the dipstick out to check it, it is covered in a debris. The debris is magnetic and resembles coffee grounds. Do you have an idea as to what may be causing it? I put pictures up over on this thread: http://www.ford-trucks.com/forums/14...-dipstick.html Thanks in advance.

    Mark, I'm back.

    My original post:

    I have a 2004 Excursion, 6.0L V8.

    I replaced (today) the #2 solenoid, and am still getting the P0976 code while the P0755 went away. I've googled and googled and what little I can find specific to this is saying a possible harness issue...

    Well, I replaced the harness today. P0976 came on again. This was the only code again. My buddy watched a real time diagnostic of the solenoids. It appears that B was constantly engaged/doing something. Shifting through the gears the other solenoids would engage accordingly.

    Solenoid B is brand new, as well as the internal harness. I'm completely at a loss. Possibly between the PCM and the transmission somewhere?

    ETA: I just read in the TorqShift Transmission Troubleshoot thread that each solenoid gets 0-1 amp or 1-0 amp respectively. I believe that is what my buddy was seeing on his reader. A was 1, B was staying around .13 when in drive. The rest were 0. Not sure if this helps.

    Thanks.

    When I first read what you did, my thoughts were that it was interesting, and maybe it was better. That's why I asked why you did it. After a lot more thinking I don't think it is as good to do it as you did. But I think it's a ways away from being a screw up. It's just not ideal.

    My first thought was that you have some cooling all the time, and if the trans really gets hot it will open the second cooler. But I think that would only work well if the thermostat had setting of about 140°F instead of 170°F

    Thanks for the reps! When I did all the research for the project that flowpath sounded good in my head. If the thermostat failed I'd still have a cooler on line. Sometimes when you get so far into it you can't see the forest for the trees. When you mentioned the temperature issue of cooling the fluid before the thermostat it seems so elementary that I can't believe I was that ignorant. Now I've just to to figure out how to change the inlet tap of the thermostat to before the radiator cooler and keep it looking (hopefully) as clean as it is now. It would be easy if it the lines were the same size. Thanks for the backup!

    Thank you so much for your reply. We will be checking the harness tomorrow. I will update when I find something out.

    Thanks again!

    Hello Mark.

    It appears that you are the trans guru!

    I have a 2004 Excursion, 6.0L V8. We recently got it, and it started throwing some transmission codes and the Tow/Haul light came on. Originally it was the P0755 and P0976 codes. Shift solenoid B and SSB Control Circuit low I believe.

    I replaced (today) the #2 solenoid, and am still getting the P0976 code while the P0755 went away. I've googled and googled and what little I can find specific to this is saying a possible harness issue...

    Does this sound correct? The truck drives and likes to stay in 3rd gear, or will stay in 1st and not want to shift at all. Thank you ahead of time for your time.

    miles excursion
    I have 2004 excursion, codes 2703, 2700, 0766 and 0751 all showing up. I have been having a shudder, almost like wheel hop, sometimes when I try to accelerate after coming out of a corner or when accelerating too fast with a heavy load. Mostly around 3rd gear, recently started in 4th too. From what I'm reading on other posts you have replied to I'm guessing these are related problems but is this a sign for complete rebuild or parts that can be replaced with removal of transmission.

    Mark, I replied back... I typed the wrong degree's the truck hits 198 not 189. I will still do your test next weekend, do you consider 198 within range driving around town? (not towing)
