Technically, a flush should be a full fluid exchange. A machine with a bladder is hooked in line. The car is started and put in gear. The transmission pump pushes the fluid through. The dirty fluid pushes on the bladder displacing the new fluid. All the old fluid (and some new) ends up in the bladder and the complete transmission system is filled with new fluid.That’s a very good question. I have no way of knowing what sort of car, or lack there of, the previous owner took. I tried looking at the car fax(I know, not the most accurate) and all that shows up is what I’ve done since buying it. Side note: it also says they did a “transfer case flush and fluid change”. They told me ford didn’t recommend changing the PTU fluid because it can be a whole can of worms. I’m gonna go I. There and have them print out the record and the service manager and I are gonna go through it line by line. Even if I’m overreacting about the trans fluid and it’s actually what I should see due to deposits, I know they didn’t do my PTU, so something’s fishy.
I tried to snap a couple this morning before I left for work. I’m no photographer so they’re probably also inconclusive. The one In the garage I’m shining my flashlight on and it looks kind of like watered down chocolate milk. I took it outside and couldn’t get good light, but it looked more like really dark red wine. (More reddish than brownish I guess.)
I’m wondering if maybe my flashlight (LED) was altering the appearance of the color. I also considered I may be thinking incorrectly about what a “trans flush” means. I don’t know if that means they’re able to get what’s in the TC or not. Maybe they just drain and run something through fill/drain area, and can’t really get to all of it without taking the trans out. So maybe it is just deposits and such from lack of previous maintenance.
I’m just gonna drain and fill every week for another 5 weeks. After that, every 3k miles with the oil change.
That being said, they could have done a drain and fill, or fluid change, or whatever other name they call it.
