I Shot That Video.
Hot Flusher Does Not Make Heated Transmission Fluid Exchange/Flush Machines! No One Does! They make Cooler FLushers. If you ask them about actually Hot Flushing a transmission they will tell you you will blow it up. Been there made that phone call.
I had to jury rig that machine to make it happen. The Rotunda machine is capable in a similar jury rigged fashion, but no Ford Dealer is going to use it that way.

The Hot Flush is an Internet Myth!!!
The service manual does not call for it and therefore Ford will not do it.

I shot that video at dead cold temps. The flush takes longer, but still works.
The thermostat is IN FACT open at dead cold temps.

DON'T WAIT TO FLUSH UNTIL YOU FIND A HOT FLUSH MACHINE!!
ANY SHOP THAT SAYS THEY DO A HOT FLUSH IS LYING AND ONLY MAKE SURE THE VEHICLE IS UP TO TEMP!

 

To add to what Mark said (to the best of my knowledge) the last time there was a drain plug on the torque converter was early 2001. After that, the bean counters said neigh to the plug and that was it.

 

Is there a schematic out there of how fluid flows thru the 5R110? I'm curious how it all pipes up, including the thermostat. A Torque-shift "Bible" like the one for the motor would be awesome, but I doubt it exists.


For flushing, I converted to the upgraded 6.4 filter and drain/refill the pan every 15k (3 oil changes). You get about half the fluid changed each time. Probably a little conservative with the upgraded filter, but gives peace of mind.

I have a folder full of 5R110W stuff. Let me know if you want anything else.

 

I believe it is in the Tech Folder also.

 

I wouldn't call it conservative at all. Remember that the fluid life is only something like 30K anyway and that's a complete system flush.

 

I thought that with the full flow filter from the 6.4 ford extended the service interval to 60k miles on the tranny fluid?

 

Awesome! Thanks!

 

If you drain and fill every 15k, it's still cheaper than 5k oil changes.

 

I always do an at home flush off the transmission cooler line. Drain the pan, then fill and remove the line to it. Drain until the color looks more red/clean. Done this at the recommended interval. 5r110 behind the 6 oh is at 220k and the 4r100 with the 7.3 is at 270k. Both doing fine, so that would be my recommendation. No problem doing changes before recommended interval either, it will cost around $100 but that's a lot cheaper than a new transmission!

 

Did you have to use a special tool to remove the cooler line from the radiator?

 

If the trans is cooler than 170F when you do this you're doing a lot of mixing old with new before it comes out of the cooler line.

 

Yes and it can be a MAJOR PITA.

OTC makes a little plastic tool that is said to do the job. Most find that is does not last
and the metal ones do't always fit correctly. There is one out there that is said to work
wel. I don't recall who makes or the part number. Someone will and they can post it.

No special tools just pull the exit line and start the truck to let it **** out. I put a thick hose around the exit line so I can let it **** more directely into the drain bucket. As said above if it is not warm it will mix more clean/dirty.

 

I can't hardly get my transmission fluid to 170 degrees. Easiest thing to do is a series of drain/fill operations from the pan.
