I have an Escort ZX2 with 60k and a transmission flush has been recommended for $270. There are no shifting issues with the car; the recommendation is based on the color of the fluid having gotten worse since the last time I took my car in. I bought the car from a dealer at around 33k miles. Not sure if they did any trans service at that time, but looking back, doubt it.
Not being familiar with these $270 "flushes" (I'm only familiar with the old-fashioned $50 drain and fill specials), I did some checking around and there seems to be a lot of conflicting opinions on whether it's better to get the flush or just go with the traditional service.
The car will be paid off in two more months so on the one hand, I want to do whatever will give the transmission the longest life, and if that's the more expensive flush, so be it. On the other hand, I'd really hate to risk anything that could result in my needing a new transmission right when I should be enjoying no more car payments. And from what I've read, the flush is risky business.
My owner's manual says not to use additives, etc and that's part of the BG flush system so that's another reason why I'm questioning the flush. And you don't even get a new filter with the flush. I'm tempted to save the add'l $200 and just go get the traditional drain, fill, and filter change special offered by another shop. But if it's true that these traditional "drain and fills" only change out about 1/3 of the fluid, maybe the flush is indeed the better path for trans. longevity?
