Trans Fluid change times????

My EX has 102000 and I am not sure when the trans has been changed. It is not acting up but after reading here is it time? Does it have the same trans as ours? E4OD?

Sorry in the wrong post but this is my home of info and PSD wealth.

I bought this thing with 92000 and it is stock and runs great but I want it to stay that way. As of now I can only afford mods on one 7.3 at a time you know what I mean. Just a PM question.

yes change it out. 25 to 30k is the sevice interval i recommend. i do mine sooner most times. i drain the pan (added a drain plug) and drain the toque converter. then refill. then every other time do the filter

just the regular stuff is what I use. Mercon dexron 3 or mercon 5 which is now ford approved for all ford trannies. I am not real crazy about using mercon 5 in mine. I have been told by that come the end of the summer dexron/mercon will not be made and only mercon 5 will be availible. Not good in my book! but who knows it could all be in my head too!

I have an 01 Ex with V10, so I don't know for sure if it's the same transmission, but mine's a 4R100. If you search, there is a good write up here on FTE for a DIY service that covers the E4OD and 4R100. Last time I did mine I got the filter from Ford for about $45 if I remember right. I also bought the pan gasket, but it turned out to be a nice rubber reusable one so I never used it. It's time to do mine again, and I'm going to add a pillar pod for a trans temp guage.

I usually drain the pan and refill every other oil change and I do the filter and dump the convertor also about 20-30k. I pull a lot of heavy trailers with my trucks though.

Ford has been working on the switch for quite some time. The last ford dealer I worked at was about 5 years ago and all we had was barrels of the mercon 5.
At the time a lot of transmission shops were saying it would mess up the seals in transmissions not intended for it. I never saw it mess one up though. I converted my 91 f150 to a 80 model C-6 and after I rebuilt it always ran merc 5. It went over 400,000 excrutiatingly expensive miles at 8 miles per gallon with merc 5 in it.

Napa filters are just as good as ford I believe and much cheaper usually.

oh I forgot. i have this 60,000 mile number in my head. it's been there a while like i heard that a while ago and it stuck or i have heard it more than once. i guess 30k is not bad, that's less than once a year. well for me anyway. i did do 30k in one year one time.

I wish I had paid as much attention to the trans in my wifes car as I do the truck. Her car is a 97 Taurus and it just fried the trans. Actually the pump broke in it. It will be sitting there till I get time to fix it. Meanwhile I get to play chauffeur. I wish she would learn to ride one of the many horses we have though. It would be much cheaper.
I did 100K my last year in the Navy. I had to do a lot of trips between LeJeune, Charleston, Memphis and Norfolk. I average about 50-60 k a year now. Boy was that an expensive year for gas!

Mine drove it for a week with a grinding noise but didn't tell me about it. It was the pump shaft bushing going. I have a whole drawer full of bushings in my tool box. The updated oversized ones. I could have fixed it real cheap before it actually broke the shaft. Now it's trashed. To make it worse I only paid 2000 dollars for the car, now it's going to cost me about half that to rebuild the trans.
