TECHS...Dealer Hot Flush
Ok, lets get to the bottom of this. Question for you Ford Tech's. Does the Hot Flush procedure recycle the oil? Basically, am I getting oil in my trans from the truck prior to me? I need to know how this thing works. Can one of you guys post some pictures of it?

At 300 bucks to get this flush done, you better not be getting old fluid from the last truck.
I think I will just stick to a drain/refill of the pan and new external filter every other oil change.

While I'm no tech, I'm reasonably certain that a flush machine receives fluid pumped from the transmission, and pumps an equivalent amount of brand new fluid back through the return line. Heated flush machines are required for the 5R110 transmission, and these pump heated fluid back into the transmission.

I guess that's not quite so bad. I just saw a post from another member the other day that said their dealer charged $300.

The purpose of a flush isn't to recycle used fluid, but to replace all the fluid in a transmission with new fluid. As opposed to dropping the pan and only getting ~2/3rds of it.

I think I read somewhere that a hot flush uses 20-21 quarts, compared to 7-8 for a drain and fill, and the total 17-19 quart capacity of a 5R110. If you're buying more fluid than the trans holds, you shouldn't get any old junk. I wouldn't be worried.

No, that's impossible. Old fluid is sent to a tank and new fluid replaces it from a separate tank.
