4R75W Tranny Flush - cut into the lines?
I have a 2004 Expy with a 4R75W Tranny according to the door pillar. I took it in for a flush today at 31K miles and was told (after two techs stood under there for 20 minutes) that they had to cut the tranny line in order to insert the flush machine lines into the system.
I could tell they haven't done it before by the amount of different people who went under to look.
Is this true. No fittings?
Does anyone recommend for or against this?
Thanks---Bob

STAY AWAY from Jiffy Lube type places when doing this... remember they have High School Kids working there... I lost an entire tranny as a result of their work (I'm convinced as it was working FINE before the flush and started shifting BADLY within 50 miles... got worse and worse until the Clutches went bye bye)...
Might cost a few more $$ but AAMCO or Cottman have people that have SEEN a transmission before

I am begining to learn that there is a release tool for the line going into the cooler.
I wish I had more info on the tool itself.

run from that place. those lines are over 200.00 to replace and are not made to be cut they are nylon braided rubber with a nylon outer jacket and crimped aluminum fittings. keep in mind in that tranny there is a big magnet in the pan to catch metal and when it gets full it will not work right you need ot drop the pan and clean it. the gasket is reusable. it takes mercon v too which most of those places don't have they just add regular atf and some modifier. bad idea.

Do yourself a favor if you can afford it, just go to a ford dealer. Otherwise, I'd just drain what I could myself and refill. Maybe do this at half the recommended interval.
I called my dealer and their version of a flush was "drain and refilll" for about $200. Glad I did it myself since I would not have gotten a flush anyway.

Personally, I like to drop the pan, change the filter, then add the few quarts to fill it up. Then I open the line "after" the cooler in the radiator, and drain out the old fluid into a big pan until I have run basically the remainder of the quantity needed to fully change the fluid, plus an extra quart to make sure it all got changed. Connect the line back up, and check the fluid level.
Full flush with new filter, and you can clean the magnet.
machine flushes typically do not change the filter.

Pretty sure this is right, and have seen it as the procedure many times. curious as to how fluid would remain in the torque converter, as that is part of the trans flow, or is it?
Oh yeah, forgot that part of what I do on the expedition is drain the torque converter as it happens to have the plug in it. On other vehicles that don't have the drain plug, changing the fluid as above still gets that fluid, you just have to wait for the old to get out first.
