    Thanks for your input on the 4R100 towing in overdrive question. Also, I went with your recommendation for a trans oil cooler setup and I'm impressed with the results. Thanks again!

    I made it to the Boarder and back to where i was camping (4 1/2 Hrs each way). Today I took apart the Main valve body and found drill chips in the Solenoid Regulator piston, along with bits in other various circuits.. I cleaned it all up, blew it out and put it all back together and........ YES!!!! it is working as intended.

    Thank you so so much for responding to my messages. You truly are a lifesaver!

    Hi Mark,

    I have almost made it to the Border. When I began the trip yesterday, the OD was already flashing. So I left it in Limp mode thinking the added pressure would help from slipping. About 2/3 through the 270Km trip I reset the Fault and turned OD off. The Transmission still behaved the same, but didn't throw a code. (2nd Manual and 4th in D only)

    I don't know if i will have internet at the border so i wanted to ask you if I can remove the main valve body while the transmission is still in the truck? Will i have check ball falling in my face?

    Thanks again,

    Ah Ha... well further developments. I found out i need to cross the border by the 28th or they could impound my truck...,
    So I am "limping" this from the middle of Colombia to the Ecuador Border. I drove about 200 miles today in mostly flat tropical highways.
    Just in the last 20 miles it finally threw a code P1728 Slip...YIKES i hope i am not destroying my TC. the temp goes from 180 to an occasional 200. and the oil is in good shape.
    I don'[t really have much of a choice, I am trying my best to Baby it. is it better to drive it in Limp mode, or reset it and turn OD off??

    Thanks again.. you are my only lifeline right now..
    i appreciate your help

    Side Note:

    I'm not sure if this has anything to do with the problem, but a week or two ago I bought some gauges. The tranny temp gauge goes into the pressure port on the drivers side of the tranny. Well, the bolt was frozen and stripped out. I eventually had to drill and easy-out the bolt. I was really careful trying not to get any chips into the system, and even let a bit of fluid drip out hoping to carry and debris out with it. Everything had been working fine for a few trips back and forth to town. Perhaps a small chip worked its way into the system???? would this explain my symptoms?

    Thanks for getting back to me

    No, There is +12 v on pin 1 and 12, SS1 goes to ground when i am in park, reverse, and when I just start to drive. Then when I'm going like 10 mph SS1 and SS2 both go to ground (2nd) so the PCM seems to be working properly, but it never shifts.
    It also shows the coast clutch solenoid is energized.
    So, I'm getting power to the valve body, and the PCM is sending the right signal to the solenoids.
    Not in Limp mode (no OD blinking) and no faults

    I really appreciate your help with this, cause I am stuck.

    Hi Mark,
    I am traveling in South America with my '97 F250 and you helped me out a year or two ago with my E4OD

    Well, now i am in Colombia and having trouble again. Would this be a good place to talk about a problem? Or do i need to start a new thread?
    It is about the tranny acting like it doesn't have power to Valve Body (starts in 4th, only goes to 2nd when in Man 1, Man 2. Reverse works fine)

    I look for DTC codes on my Auto engenuity with enhanced powertrain module but nothing comes up.

    Tested: Relays, Fuses, Changed Valve Body, Valve Body Voltage, Ohms on Coil, MLPS, TPS, Wiring Harness, Pressure, tach, speedo, PCM outputs.
    even tried to ground SS1 while in D.. but no change

    My next thought was to do the Air Pressure test, but i don't want to get my new oil dirty... and I'm nervous to break open the brain.

    Any thoughts of something else I could test?

    Thanks for your help again

    ok thanks for the info
    yes it was the solenoid pack which took care of 2 gear jumping in and out
    I will check out some info on the motor and see what I could find
    i was reading about the by pass tube in an article from i think it was john wood would it be worth it to fi the bypass tube or just leave it alone
    thanks again

    then when I take it out of drive to netrual it drops the rpms back down
