RE: How often should I do a Transmission flush?
My limited knowledge tells me $300 is high, but not an outrage. And 13 quarts is not too much because they have to "flush" the thing, so that means they have to run fluid through it to clean out the dirty stuff, in addition to replace the old fluid. So that leaves the antifreeze change, which also means they have to "flush" the thing for it to be done right, but they can use water to flush, then replace with 50/50 antifreeze mix.
Now all this supposes they did the proper job, didn't skimp. My question is this: Did you do it at the dealer, or did you go to another shop someplace? The reason I ask is because they were supposed to use the Hyundai spec trans fluid, and not Dextron II or III. Anything less is wrong, and it needs to be changed again.
So again... where did you have it changed? And what kind of fluid did they use?
