It sounds like your tranny or torque converter has already packed its bags and getting ready to go south. If it goes south right after you change the ATF, it won't be because you changed the ATF.

I would not use a chemical of any sort to flush the tranny. That can cause a world of hurt. Just follow Mark's procedures and you'll be good to go.
Marks procedure sounds correct but since its an old wives tale what the hell do the Ford dealers put in the trannys to ruin em within a month of so called flushing them? I know of far too many people who have had the Ford dealer flush it and it take a crap within a month. Just seems kind of ironic how a perfect transmission goes to hell in a week or two after they flush it (7 people to be exact).

Perhaps, it was giving them trouble and they thought a flush would fix it?

Dunno, but I do know we changed tranny fluid in a motorhome back in the 80's and it took a dump a month later, but didn't flush, just did pan fluid and filter.

I have a powerstroke 7.3 Yr 2000
Has 318800 miles.AT I have heard you can damage the transmission if you change the fluid,because the detergent will wear whats left of plates and cause breakdown. What is your take and what would you do if it was your truck. It is all Highway miles towing a #13000 5th wheel

Have you never changed the ATF?
Some say that not changing is more damaging, but then there is the others that say changing will have it go south.
We change engine oil and the coolant, why not ATF every x miles?

The rumor that changing the ATF might harm the 4R100 tranny is a bunch of horse hockey. Fresh ATF is not going to hurt a 4R100 tranny. If it were mine, I'd change the ATF immediately, using Mark's procedures, and 20 quarts of Mobil 1 ATF.

I take it you mean Mobile 1 Syn.
That hurts being money is tight. What is best for the miles I have? Probably syn huh. Just have to cough up the greenbacks and don't wine about it, right? trans more important than cheap fluid.

Miles don't matter. How hot your tranny gets is what matters. If you ever see over 210°, you need full synthetic, such as Mobil 1 ATF. If you ever see 205° to 210°, you need synthetic blend, such as MotorCraft MERCON V Synthetic Blend. If you never see 205°, then you can probably get by with Motorcraft dino MERCON V, or even the cheaper Wal-Mart house brand of SuperTech MERCON ATF.

I never saw over 205° on mine, but I used Mobil 1 ATF just in case I ever got in a situation where I would get the tranny really hot.

trans filter problem

Yesterday at Carquest I bought a 96050 deep pan filter for my 1999 f250 7.3 transmission. The filter I removed was for a deep pan, but a paper in the box showed a picture with a short length filter for 2wd, long for 4wd. I Measured how much the pick-up tube hung down(4 inches+-), the depth of the pan-Right filter? Does the tube support the filter flat on the pan bottom? I installed the filter-(tube in hole) the filter just hung there at an angle, it didn't fasten in at the other end. I centered the filter where a trans screw lined when held up, but fear the filter could get moved over when I put up the pan? Any thoughts? Thanks

The short 2wd filter is for pre-99 E4OD 2wd trucks. All 4R100s use the longer filter.

This forum is awesome. I really appreciate the guys who help people out. Thanks guys.
I was always curious what overfilling oil can do to the truck and how much is over full. I did oil this am and ti is about 3/16 above the safe operating line. Could this really hurt the engine?

If the oil is overfilled it can get whipped into foam by the crankshaft. Foamed oil can't lubricate, so you'll have metal to metal wear and if that gets bad enough you'll need a new engine. I don't know how much overfilled is too much. I never fill an engine all the way to the top of the full mark.

Flushed it! Just completed the flush via the Mark Kovalsky / SmokeyWren Way. Excellent results. Worked just as they said it would. Dropped the pan and replaced the screen/filter. Used M1 Synthetic. Clear tubing was the just the ticket. My dad was the bucket and hose man while I started the engine. Flushing the transmission in the barn with my dad and being by the warmth of the wood stove made it all the better! Thanks for your expert advise and for saving all of us a lot of guesswork.

Did mine this past Sunday, per the instructions, and with a filter change. Used the Mobil 1 Synthetic. With the wife in the cab, and me doing the rest...start to finish was about an hour.

Very easy. I wish I had back all that money I spent paying someone else to do it these past 10 years.
