Transmission Flush

My buddy gets great deals on amsoil products so I bought transmission fluid for my 2000 X 7.3L w 218k miles and took it to my local diesel mechanic and they said I should not flush because it could shock the transmission. The transmission is original. Is there any truth to this?

Yes. Don't do it.

Funny but not so funny. I flushed mine with amsoil a month after I got my rig. Two weeks it was toast and I never pulled anything with it. I dropped the pan and all of the clutches were muck in the bottom.
But now I got a BTS

And yes, I put Amsoil back in it.

Your fine. You can swap the fluid without issue. Disconnect the supply line of the trans that goes to the cooler. Start the truck and drain out 3-4 qts, then add back, then do the same thing but at one time pull the truck thru reverse and drive and 1-2 to get all the fluid out.

LOL... Ya, its always smart to NOT service your tranny... By doing proper service you will cause it to blow up...


Change the fluild, there is no such thing as a power flush anyway and there is no risk of damage by properly servicing the tranny.

Ive heard two schools of thought on servicing trannys with 200,000+ that havent had a change before, which is true or truer? that if you replace all the fluid with new, the detergents in ATF washes the varnish off the clutches and causes it to eventually fail, but then ive also heard that if you only drop the pan then the new ATF cant bond correctly with the old fluid still in the converter and again eventually causes failure. Is either of that true, i have never messed with many auto trannys before but its getting about that time for me as well

This info is from Brian Thompson owner of BTS. Not word for word though if someone wants to be annoying.

Never flush the transmission. Just normal service of the filter and replace only what was removed from the pan and top off what is necessary.


Keep up on your normal maintenance schedules and you'll be golden.

And my info comes from the design engineer that designed, tested and worked for Ford...

Where in any of the info above does it say the tranny has never been serviced? Why is it that Ford recommends full tranny service every 30-50k?

Service your trans, no matter what the resident forum IDE (internet diesel expert) says to do...

Here we go again. Lol.

Your design engineer is the reason Brian and John Wood and other reputable shops are doing such excellent business.
