    Thanks for your swift response(s).

    Looking like it might be up to a week before I can get back to working on the truck.

    Thanks again for your direction

    Got it apart, found 2 or 3 tablespoons of metal debris in pan - as much as maybe 1/4" long and pencil lead in diameter.

    Put back together with the 2 solenoids TP filter and 8 .5 quarts fluid.

    Does no engage till about 2000 - 2200 RPMS, did not take out of driveway.

    Also getting P0720 code now.

    Any suggestions.

    Thanks

    Thanks, I will replace solenoids, external filter, fluid.

    Have internal filter here also if contaminated.

    Fluid was last changed less then 10k miles.

    I have a chart showing those pressures.

    Thank you very much.

    Hi Mark. 2005 6.0 auto.

    code P0752 and P2700. Tow/Hall lite when down shifting then stays on. Did pressure test, @ idle 50-55 PSI all shift positions, did not move much at all, stalling @ about 335-350 PSI all positions.

    Stopped shifting into 6th it seemed (had 1.5k camper and jeep on trailer behind), often does not engage 1st & Reverse till about 1200 RPM. It did not all ways do this. I only drove it home which was about 275 miles (all high way only about two down shift events)) when lite came on. Coming home I shut down ignition & lite went off and only returned when down shifting ocurred, maybe into 3rd or less ?. I reloaded tune (SCT) and test drove and moved to run pressure test, that is all I have driven it since it occurred.

    Thanks

    Hello,
    I was told to contact you and see if you would take a look at my thread and possibly give some insight.
    Any help is very appreciated. Thank You in advanced. Power Strokes 1994-1997 General / clutch fan vs. straight fan.
    It did get off topic from the subject but certain ideas popped up that left more questions and areas to dwell on.

    Hello Mark, I just got a 2010 F250 6.4 D. 90K miles. I want to flush ALL the fluids and change filters. I got a quote from a local shop for 1600.00. Little high for my budget. needs power steering and tranny for sure. That plus oil lands me at $800.00. Is this a fair price? Anything you would recommend at this mileage for preventative maintenance?
    thank you sir,

    Hello Mark, Newbie here with an engine tranny swap question. Can I bolt a newer 2001 7.3 engine up to an OBS 1997 7.3 which has the E4OD tranny ? Or do I need the 2001 4R100 trany, T-case and complete truck wiring harness with it also? Thanks for your time and info.
